Abstract:
Rapid growth in the global energy requirement coupled with rapid depletion of non-renewable fossil fuel necessitates alternative sources of energy. Alternative sources need to be efficient, inexpensive and environmentally sustainable to mitigate the future global energy challenges. Solar energy is the ultimate source of energy for almost all life on Earth either directly or indirectly. Photosynthesis is the direct way of harvesting solar energy whereas, fossil fuels are a product of photosynthesis over millions of years. If it is possible to mimic nature, solar energy can be directly harvested in the form of photovoltaic (PV) technology for the global energy landscape in the cleanest possible manner.
