Solar cell - has first conducting silicon substrate, silicon oxide layer, micro-crystalline or amorphous silicon layer of second conducting type, etc.

摘要

A solar cell comprises a silicon substrate (1) of a first conducting type, a silicon oxide layer (2) of required thickness, a microcrystalline or amorphous silicon layer (3,3a) of a second conducting type, a transparent electrode (4), a grid electrode (5), and on the rear side of the substrate a rear electrode (6). USE/ADVANTAGE - The output characteristics and reliability are enhanced and the prodn. stability of the microcrystalline or amorphous silicon layer is raised. A solar cell (2) of raised conductability is obtd. at reduced cost.
