THIN FILM PHOTOVOLTAIC MODULE WITH STABILIZED POLYMER

摘要

The present invention provides a photovoltaic device comprising metal and a polyvinyl butyral) layer that incorporates a suitable amount of 1 H- benzotriazole. When electrical bias is applied to the photovoltaic device, 1 H- benzotriazole forms a barrier layer at the metal/poly(vinyl butyral) interface, which, for example, unexpectedly virtually eliminated the yellowing of polyvinyl butyral) in photovoltaic devices comprising silver components.
