ABSTRACT:
A solar cell has a rear electrical contact for the semiconductor body of the cell forming an intersecting pattern which includes rows of contact pads which are parallel to a pair of sides of the body; a set of contact strips which also are parallel to such sides; another set of contact strips which are parallel to another pair of sides of the body perpendicular to the first pair of sides; and yet another set of contact strips which are angularly oriented with respect to both pairs of sides of the body. The contact pattern permits the passage of radiation through the cell which would otherwise decrease efficiency due to heat generation and incorporates additional features designed to balance a desire for transparency to such radiation with a requirement for efficient charge collection along the rear of the cell. The front electrical contact for the semiconductor body forms an intersecting pattern, designed to balance the requirement for the entry of solar radiation into the body with the efficient collection of charges at the front of the solar cell, which is similar in some details to the rear electrical contact but significantly different as to other details.
