Title: Solar cell with doped groove regions separated by ridges

Abstract

Solar cells with doped groove regions separated by ridges and methods of fabricating solar cells are described. In an example, a solar cell includes a substrate having a surface with a plurality of grooves and ridges. A first doped region of a first conductivity type is disposed in a first of the grooves. A second doped region of a second conductivity type, opposite the first conductivity type, is disposed in a second of the grooves. The first and second grooves are separated by one of the ridges.

Schottky barrier amorphous silicon solar cell with thin doped region adjacent metal Schottky barrier

Patent Carlson, David E [Yardley, PA]; Wronski, Christopher R [Princeton, NJ]

A Schottky barrier amorphous silicon solar cell incorporating a thin highly doped p-type region of hydrogenated amorphous silicon disposed between a Schottky barrier high work function metal and the intrinsic region of hydrogenated amorphous silicon wherein said high work function metal and said thin highly doped p-type region forms a surface barrier junction with the intrinsic amorphous silicon layer. The thickness and concentration of p-type dopants in said p-type region are selected so that said p-type region is fully ionized by the Schottky barrier high work function metal. The thin highly doped p-type region has been found to increase themore » « less

Trench process and structure for backside contact solar cells with polysilicon doped regions

Patent De Ceuster, Denis; Cousins, Peter John; Smith, David D

A solar cell includes polysilicon P-type and N-type doped regions on a backside of a substrate, such as a silicon wafer. An interrupted trench structure separates the P-type doped region from the N-type doped region in some locations but allows the P-type doped region and the N-type doped region to touch in other locations. Each of the P-type and N-type doped regions may be formed over a thin dielectric layer. Among other advantages, the resulting solar cell structure allows for increased efficiency while having a relatively low reverse breakdown voltage.

ZnO/Cu(InGa)Se₂ solar cells prepared by vapor phase Zn doping

Patent Ramanathan, Kannan; Hasoon, Falah S.; Asher, Sarah E.; ...

A process for making a thin film ZnO/Cu(InGa)Se₂ solar cell without depositing a buffer layer and by Zn doping from a vapor phase, comprising: depositing Cu(InGa)Se₂ layer on a metal back contact deposited on a glass substrate; heating the Cu(InGa)Se₂ layer on the metal back contact on the glass substrate to a temperature range between about 100° C. to about 250° C.; subjecting the heated layer of Cu(InGa)Se₂ to an evaporant species from a Zn compound; and sputter depositing ZnO on the Zn compound evaporant species treated layer of Cu(InGa)Se₂.
