Abstract
Disclosed herein are electrically conductive adhesive compositions and their use in solar cell modules, wherein the electrically conductive adhesives comprise one or more olefinic carboxylic acids or derivatives thereof.
Claims17
An electrically conductive adhesive composition comprising:
- a) a binder formed of or comprising at least one peroxide curable elastomer and at least one peroxide-based curing agent;
- b) 40-93 wt % of conductive particles dispersed in the binder;
- and
- c) 0.1-1.5 wt % of olefinic carboxylic acid or derivative thereof dispersed in the binder, with the wt % of all components comprised in the composition totaling to 100 wt %, and wherein, the olefinic carboxylic acid has a formula R1CO2R2, R1 being hydrocarbyl or substituted hydrocarbyl having 4 or more carbon atoms, and containing one α-olefinic double bond, provided that the double bond is not part of a ring;
- and R2 being hydrogen, hydrocarbyl, or substituted hydrocarbyl.
