Abstract
A photovoltaic energy conversion device and methods for forming the same with relatively high efficiency, high stability, low cost, low weight, and low toxicity. The device comprises a thin film n/p or n/i/p type, gradient-doped heterojunction which uses compatible, lattice-matched, non-hazardous semiconducting compounds from the I-III-VI.sub.2 (14), I-III-VI-VII (15) and I-VI.sub.3 -VII (16) series, an ohmic contact (13) to the n-layer comprising a group III metal, a transparent ohmic contact (17) to the p-layer, a grid (18), and an antireflection coating (20).
