    摘要: A thin film solar cell including a Group IBIIIAVIA absorber layer on a defect free base including a stainless steel substrate is provided. The stainless steel substrate of the base is surface treated to remove the surface roughness such as protrusions that cause shunts. Before removing the protrusions, a thin protective ruthenium film is first deposited on the recessed surface portions of the substrate to protect these portions during the following protrusion removal. The protrusions on the surface receives very little or no ruthenium during the deposition. After the ruthenium film is formed, the protrusions are etched and removed by an etchant which only attacks the stainless steel but neutral to the ruthenium film. A contact layer is formed over the ruthenium layer and the exposed portions of the substrate to complete the base.

A first buffer layer is formed on the absorber and the first buffer layer is then treated using etching, oxidizing, annealing or some combination thereof. Subsequently a second buffer layer is then positioned on the treated surface. Additional buffer layers can be added following treatment of the previously deposited layer.

    摘要: The present invention provides a method and precursor structure to form a solar cell absorber layer. The method includes forming a CIGS solar cell absorber on a base by depositing a first layer on the base, where in the first layer includes non-crystalline copper-selenide that is electrically nonconductive, and then heat treating the first layer at a first temperature range to transform the non-crystalline copper-selenide into a crystalline copper-selenide that is electrically conductive, thereby ensuring that the first layer becomes a first conductive layer. Thereafter, other steps follow to complete formation of the CIGS solar cell absorber.
