p-Inp/n-CdS heterojunction solar cells

Abstract

For photovoltaic collector arrays, heterojunction devices should be studied more extensively. The advantages of the InP/CdS cell are outlined, both as single-crystal InP with deposited CdS and as an all-thinfilm cell. Present work on the single-crystal InP with sputter-deposited CdS is described, and plans are given for polycrystalline thin films using r.f. sputtering.
