ABSTRACT:
This complementary photovoltaic cell has both an N+/P+ junction and a P+/N junction on the same epitaxial substrate, and so provides simultaneous photo-responsive outputs of both negative and positive polarity. A vertical photo-junction supplements the current output from the N+/P+ junction, and improves the efficiency of the cell. The N+/P+ junction by itself exhibits a high open circuit voltage.
