A photovoltaic device includes a substrate structure and at least one Se-containing layer, such as a CdSeTe layer. A process for manufacturing the photovoltaic device includes forming the CdSeTe layer over a substrate by at least one of sputtering, evaporation deposition, CVD, chemical bath deposition process, and vapor transport deposition process. The process can also include controlling a thickness range of the Se-containing layer.

Photovoltaic devices and method of manufacturing

A doped photovoltaic device is presented. The photovoltaic device includes a semiconductor absorber layer or stack disposed between a front contact and a back contact. The absorber layer comprises cadmium, selenium, and tellurium doped with Ag, and optionally with Cu. The Ag dopant may be added to the absorber in amounts ranging from 5&#xd7;10/cmto 2.5&#xd7;10/cmvia any of several methods of application before, during, or after deposition of the absorber layer. The photovoltaic device has improved Fill Factor and Pat higher P(=I*Vproduct) values, e.g. about 160 W, which results in improved conversion efficiency compared to a device not doped with Ag. Improved PT may result from increased I, increased V, or both.

Ag-doped photovoltaic devices and method of making

A method and system for controlling the amount of a second material incorporated into a first material by controlling the amount of a third material which can interact with the second material.

Method and system of providing dopant concentration control in different layers of a semiconductor device

A method to improve CdTe-based photovoltaic device efficiency is disclosed. The CdTe-based photovoltaic device can include oxygen or silicon in semiconductor layers.
