Abstract:

Provided is a solar cell module that comprises a solar cell assembly. The solar cell assembly is encapsulated by a poly(vinyl butyral) encapsulant and contains a silver component that is at least partially in contact with the poly(vinyl butyral) encapsulant. The poly(vinyl butyral) encapsulant comprises poly(vinyl butyral), about 15 to about 45 wt % of one or more plasticizers, and about 0. 1 to about 2 wt % of one or more unsaturated heterocyclic compounds, based on the total weight of the poly(vinyl butyral) encapsulant. Further provided are an assembly for preparing the solar cell module; a process for preventing or reducing the discoloration of a poly(vinyl butyral) encapsulant in contact with a silver component in the solar cell module; and the use of the solar cell module to convert solar energy to electricity.

US Classification:

136251, 438 66, 257E31117

Abstract:

Provided herein is a process for fabricating a solar cell module that is resistant to discoloration. The solar cell module comprises a solar cell assembly and an encapsulant. The solar cell assembly in turn comprises a solar cell and a metal component. The encapsulant is in contact with the metal component. The process comprises the step of applying an additive that prevents or reduces discoloration to the encapsulant or to the metal component. Further provided is a solar cell module that is a product of the process described herein.
