Patent Number Title Of Patent Date Issued
4575577 Ternary III-V multicolor solar cells containing a quaternary window layer and a quaternary trans March 11, 1986
Two- and three-terminal ternary III-V two-color and three-color solar cells which incorporate GaAs.sub.1-x-y P.sub.x Sb.sub.y transparent window layers are described. The window layers lower the surface recombination of the incident homojunction layer.
4451691 Three-terminal ternary III-V multicolor solar cells and process of fabrication May 29, 1984
Three-terminal ternary III-V two-color solar cells incorporating layers of GaAs.sub.1-x-y P.sub.x Sb.sub.y. The three-terminal structure enables the current to be withdrawn from both cells without the necessity of current matching between the two color stacked photovoltaic device. In add
4404421 Ternary III-V multicolor solar cells and process of fabrication September 13, 1983
Ternary III-V multicolor solar cells incorporating layers of GaAs.sub.1-x-y P.sub.x Sb.sub.y and an improved process of fabricating multicolor photovoltaic III-V compound photovoltaic devices.
4332974 Multilayer photovoltaic cell June 1, 1982
A new high efficiency, multijunction photovoltaic solar cell for use with a concentrating lens. This cell comprises an elemental single crystal substrate without an internal light sensitive junction, upon which are two or more successive homogenous layers of semiconductor material, each
4255211 Multilayer photovoltaic solar cell with semiconductor layer at shorting junction interface March 10, 1981
A new high efficiency, multijunction photovoltaic solar cell for use with a concentration lens. This cell comprises an elemental single crystal substrate without an internal light sensitive junction, upon which are two or more successive homogenous layers of semiconductor materials, each
