Study on the Influence of Light Intensity on the Performance of Solar Cell

Table 1

Types and characteristics of common photovoltaic cells.

Type	Monocrystalline silicon	Polysilicon	Amorphous silicon
Photoelectric conversion efficiency	12%~17%	10%~15%	6%~8%
Service life	15-20 years	15-20 years	5-20 years
Average price	Expensive	More expensive	Cheaper
Stability	Good	Good	Poor (attenuated)
Colour	Black	Navy blue	Brown
Main features	The photoelectric conversion efficiency is higher than other types of batteries, with high reliability and relatively high cost	Stable and reliable operation, low cost, can be widely used, but compared with monocrystalline silicon, the conversion efficiency is lower	Low price, mostly used in calculators, electronic watches, etc., with the lowest conversion efficiency
