Problems solved by technology

The main factor limiting the further popularization and application of amorphous silicon cells is the light-induced attenuation effect, that is, long-term strong light irradiation causes defects inside the cell and reduces its photoelectric conversion performance.

A large number of experimental studies have proved that for amorphous silicon cells, this effect will be weakened at higher temperatures
