Abstract
Official abstract text for this publication.
A method of making a photovoltaic device is presented. The method includes disposing an absorber layer on a window layer. The method further includes treating at least a portion of the absorber layer with a first solution including a first metal salt to form a first component, wherein the first metal salt comprises a first metal selected from the group consisting of manganese, cobalt, chromium, zinc, indium, tungsten, molybdenum, and combinations thereof. The method further includes treating at least a portion of the first component with cadmium chloride to form a second component. The method further includes treating at least a portion of the second component with a second solution including a second metal salt to form an interfacial layer on the second component, wherein the second metal salt comprises a second metal selected from the group consisting of manganese, cobalt, nickel, zinc, and combinations thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making a photovoltaic device, comprising: disposing an absorber layer on a window layer; treating at least a portion of the absorber layer with a dopant solution comprising a dopant metal salt to form a first component, after the step of disposing the absorber layer on the window layer, wherein the step of treating at least a portion of the absorber layer with a dopant solution consists essentially of a soaking treatment wherein a portion…
