ABSTRACT:
A silicon solar energy cell having improved anti-reflective properties and resistance to radiation is composed of a light receiving surface having spaced indentations in the form of inverted pyramids therein. The pyramids, which have their bases in the plane of the light-receiving surface, are produced by masking the surface with a layer resistant to attack by a silicon etchant, forming open regions in the mask, then etching the major surface through the exposed regions.
