It was posited in Gratzel study in that covering 0. And yet the developing countries of Africa and other regions are wallowing in energy poverty leading to high unemployment, abject poverty and terrifying standard of living. Till date the energy generated from the sun is less than 0. The energy generated from the sun is limited by certain factors which include cost of producing solar cells and the PV cell converting efficiency. To raise the conversion efficiency of solar materials has attracted a lot of interest.
Previous attempts reduce the effects of these factors yielded successes and studies are still on going to break more grounds. The attempts have been multi-criteria improvement approach, which has led to the three categories of PV cell materials today — first, second and third generations of PV materials. Several interventions to alter the present power situation in most developing regions, especially in sub-Saharan Africa and Asia South India , have not yielded the expected results. The impacts of the interventions have been engulfed by challenges arising from global technologies landscape changes, which led to several disruptions in the industry.
Therefore, a fresh and systematic power infrastructure investment will be needed to meet the current and future energy demand in developing countries. Solar energy is seen as the best option for alternative energy source because of its abundance, and environmental friendliness. This chapter aims to analyze the global energy trends in terms of achievements, challenges and outlooks. The study X-rays global energy accessibility and the role of PV solar cell system in achieving global supply of energy with modern energy attributes.

Further, the significance of nanotechnology in enhancing the efficiency of PV solar materials was discussed. Trends of power disruption in SSA [ 5 ]. Large populations have no access to modern energy in many rural and remote areas of developing countries. It has been predicted that the population without access to electricity in rural areas of SSA would increase from million in to million in [ 11 ]. The concerted efforts and interventions from both domestic and international arenas to change this scenario have not yielded the expected results.
The fossil fuels for power generation are characterized by climate change, greenhouse gases GHG emission, and global warming. For decades, fossil fuels, such as diesel, petrol, coal, and natural gas have proved to be efficient economic development drivers but with health and environmental consequences. Fossil fuels environmental challenges include climate change, global warming, and CO 2 emissions. These negative fallouts have not deterred man from fossil fuel usage because of energy significance to human existence and industrialization.
The amount of GHG emission is vastly different amongst countries but is associated with industrialization. The annual CO 2 emissions from fossil fuels combustion have abruptly risen since the Industrial Revolution from near zero to more than 33 GtCO 2 in The highly industrialized countries contribute most to CO 2 emission.
The International Energy Agency in estimated the CO 2 emission from industrial waste and non-renewable municipal waste and the combustion of natural gas, oil, coal and other fuels [ 15 ].
Also, there is an emergence of authorized energy consumers with new choices in how they utilize and manage their energy usage. The governance and management of this complex global energy dynamic is challenging and critical to energy security, climate change mitigation and energy poverty.
Energy sustainability was defined by the World Energy Council based on energy security, energy equity, and environmental sustainability [ 17 , 18 , 19 ]. The challenge of balancing energy affordability, energy security, and environmental sustainability could promote the understanding of the framework of the disruptions and opportunities of increased decentralization in the energy system.
To appropriately respond to these global challenges, the need to generate more energy without compromising the future becomes a clarion call. This implies the use of fossil fuel should be limited or eliminated. To effectively do this, clean, reliable and renewable energy sources of energy with low or no GHG emissions must be available. To significantly contribute to the realization of global energy trilemma, both developed and developing countries should incorporate the following into their national infrastructure planning: Increasing share of renewables.
Robust policy framework and consumer sensitization agenda on energy efficiency to reduce GHG emission, costs and risks.

Greater accessibility and reliable power supply because of growing dependency on electricity. The rising threat of cyber-attacks should be met with increased energy infrastructure automation. The introduction of more disruptive technologies, such as energy storage, PV solar, electric vehicles, and power electronics that might substantially change the energy space as the cost of technology drops.
Renewable energies have been identified as potential alternatives to fossil fuels. This is due to the notable environment benefits the renewable energies offer, such as reduced CO 2 emission and their off grid utilization. Subsequently, the renewable energy technologies are receiving immense attention. The building of renewable technologies infrastructure to increase the portion of electricity generated from renewable energy has commenced in many countries.
Policies and framework have been formulated by different countries to guide the use, the growth and the constitutionality of renewable energy. The available alternatives to the fossil fuels are solar, geothermal, tidal, biofuels, hydro, and wind. A huge capacity of the required electricity can be derived from nuclear energy. However, many countries are skeptical about the use of nuclear energy because of the perceived side effects.
They consider the use of nuclear energy for electricity as a risky venture. Amongst these natural resources sun solar , small hydropower, and wind are the most established and are considered better alternatives for environment and cheaper electricity sources in the long term. The exploitability of the solar resource in urbanization is more versatile than other renewable energy sources. Criticisms have trailed renewable energy technology due to their low energy densities, intermittency and region-based resources, making them less suitable for urban applications.
Developments in Solar Cell Technology
Solar is the most common renewable energy whose potential is highly region-dependent. Interestingly, several of the regions that are likely to experience the maximum increase in urbanization are in solar-rich regions. Subsequently, a lot of studies and technical advances have been focused on solar efficiency, structure and cost.
This makes solar photovoltaic PV generation as the greatest potential for wider utilization in Singapore. Trombe is a technique of collecting and storing of solar thermal energy in the summer for heating in the winter. Sustainable development challenges come with a rise in global urbanization in the dense cities especially in the lower-middle-income countries where the growth of urbanization is rapid.
Urban sustainable solutions in the form of integrated policies and technologies are needed globally to lower GHG emissions, reduce the cost of clean energy and guarantee safe energy. The common clean energy challenges in urban are energy intermittency and reliability, cost of installation and low power density.
Renewable energies such as wind, hydro and solar have common intermittency and reliability challenges. It is not always windy, sunny and the water level in the source is not always the same. This limits the level of providing a constant power supply to users. There are several approaches that are ongoing in tackling these challenges and these include: the combination of renewable energy sources in a hybrid system; and development of low-cost and efficient renewable energy generation and storage materials.
The goal of the combined systems is to cushion the inconsistency supply by a power bolster, either a diesel generator or pumped storage hydroelectric. The combination of renewable energy sources, such as solar, hydro, wind, diesel generator and energy storage units, have been studied extensively in recent years.
This combination is often called hybrid renewable energy systems HRES. Hybrid renewable energy system is a response to challenges of scarce supply of a single renewable resource and intermittent generation challenges. It is vital to consider the system design and operation from a range of time scales because HRES has various stages of life cycle.
Irrespective of life cycle whole life or daily , real-time optimization offers a significant opportunity to handle HRES systematically [ 29 ].

Diagram of a typical crystalline silicon solar cell. The resulting structure creates a pathway for electrical current within and between the solar cells. The PV effect was observed as early as by Alexandre Edmund Becquerel, and was the subject of scientific inquiry through the early twentieth century. In , Bell Labs in the U. The energy crisis of the s saw the beginning of major interest in using solar cells to produce electricity in homes and businesses, but prohibitive prices nearly 30 times higher than the current price made large-scale applications impractical.
Industry developments and research in the following years made PV devices more feasible and a cycle of increasing production and decreasing costs began which continues even today. Rapidly falling prices have made solar more affordable than ever. The average price of a completed PV system has dropped by 59 percent over the last decade. For more information on the state of the solar PV market in the US, visit our solar industry data page. The cost of PV has dropped dramatically as the industry has scaled up manufacturing and incrementally improved the technology with new materials.
Installation costs have come down too with more experienced and trained installers. Globally, the U.
