In reality, silicon-wafer cells achieve, on average, 15 to 25 percent efficiency. Thin-film solar cells are finally becoming competitive. The efficiency of CdTe solar cells has reached just more than 15 percent, and CIGS solar cells have reached 20 percent efficiency. There are health concerns with the use of cadmium in thin-film solar cells.
In this chapter, the working mechanism for traditional silicon-based solar cells is first summarized to elucidate the physical principle in photovoltaics. The main efforts are then made to discuss the different mechanisms for different types of solar cells, i.e. dye-sensitized solar cells, polymer solar cells, and perovskite solar cells.
The solar cell is the core electric element of the PV pavement. It is based on the photovoltaic effect first proposed by Becquerel in 1839 [42]. A solar cell is composed of a P-type semiconductor and an N-type semiconductor, while the P …
