Abstract
Thin film photovoltaic devices are generally provided. The device can include a transparent conductive oxide layer on a glass substrate, an n-type thin film layer on the transparent conductive layer, and a p-type thin film layer on the n-type layer. The n-type thin film layer and the p-type thin film layer form a p-n junction. An anisotropic conductive layer is applied on the p-type thin film layer, and includes a polymeric binder and a plurality of conductive particles. A metal contact layer can then be positioned on the anisotropic conductive layer.
