Fundamentals of Solar Cell Design. Rajender Boddula
for commercial-scale power generation. While commercial solar cells exhibit good performance and stability, still researchers are looking at many ways to improve the performance and cost of solar cells via modulating the fundamental properties of semiconductors. Solar cell technology is the key to a clean energy future. Solar cells directly harvest energy from the sun’s light radiation into electricity are in an evergrowing demand for future global energy production. Solar cell–based energy harvesting has attracted worldwide attention for their notable features, such as cheap renewable technology, scalable, light-weight, flexibility, versatility, no greenhouse gas emission, environment, and economy friendly, and operational costs are quite low compared to other forms of power generation. Thus, solar cell technology is at the forefront of renewable energy technologies which are used in telecommunications, power plants and small devices to satellites. Aiming at large-scale implementation can be manipulated by various types used in solar cell design and exploration of new materials toward improving performance and reducing cost. Therefore, in-depth knowledge about solar cell design is fundamental for those who wish to apply this knowledge and understanding in industries and academics.
