Abstract

See full text

A solar cell comprising multi-crystalline silicon or an alloy thereof, having a surface that is to receive light radiation, wherein said silicon surface includes a multi-tude of pits of depth lying in the range 0.10 .mu.m to 10 .mu.m and of diameter lying in the range 0.1 .mu.m to 10 .mu.m, and in which the ratio of said depth to said diameter is greater than 1, the area of said holes occupying more than half the area of said silicon surface.
