Solar energy has been seen as a very promising method of energy collection for electrical use for some time now. The common silica solar cell design has been altered in many ways over the years. The main goal is to improve the absorption and conversion of sunlight into usable energy. The majority of current photosynthetic solar cells make use of non-renewable components.
Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.
Theoretically, a solar cell with silicon has at least 28% efficiency in terms of the unit cell. Commercial silicon-based PV devices have low voltage (0.6–0.7 V) and high current (~9 A). The total voltage increases as each cell is connected in series; for parallel combinations, the current increases without changing the voltage.
