Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells , or thin-film silicon solar cells , it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic.
Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
An amorphous silicon (a-Si) solar cell is made of non-crystalline or microcrystalline silicon. Amorphous silicon has a higher bandgap (1.7 eV) than crystalline silicon (c-Si) (1.1 eV), which means it absorbs the visible part of the solar spectrum more strongly than the higher power density infrared portion of the spectrum.
The following are the different types of solar cells. Amorphous Silicon solar cell (a-Si) Biohybrid solar cell; Cadmium telluride solar cell (CdTe) Concentrated PV cell (CVP and HCVP) Copper indium gallium selenide solar cells (CI(G)S) Crystalline silicon solar cell (c-Si) Aluminium Back surface field (Al-BSF) Passivated Emitter Rear Cell (PERC)
This technique is widely used by amorphous silicon solar cells, Uni-Solar's products use three such layers to reach efficiencies around 9%. Lab examples using more exotic thin-film materials have demonstrated efficiencies over 30%. [17]
For most crystalline silicon solar cells the change in V OC with temperature is about −0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around −0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is −0.20 to −0.30%/°C, depending on how the cell is made.
