POLY(VINYL BUTYRAL) ENCAPSULANT COMPRISING CHELATING AGENTS FOR SOLAR CELL MODULES
摘要
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 an oxidizable metal 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 0.5 to about 2 w t% of one or more chelating agent, 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 an oxidizable metal component in the solar cell module; and the use of the solar cell module to convert solar energy to electricity.
