Abstract
Frontside metallization pastes for solar cell electrodes contain siloxanes. Metallization pastes containing siloxanes can be used to fabricate fine line, high aspect ratio, solar cell gridlines.
Claims18
A method of fabricating a solar cell electrode, comprising:
- applying a metallization paste to a surface of a solar cell, wherein the metallization paste comprises:
- silver particles;
- from 0.01 wt % to 0.6 wt % of a liquid polymethylhydrosiloxane;
- and
- from 0.01 wt % to 0.4 wt % of a polysiloxane-modified resin;
- wherein wt % is based on the total weight of the metallization paste;
- drying the applied metallization paste;
- and
- firing the dried metallization paste to provide a solar cell electrode.
