In this paper, we present results of the implementation of the RCT Solutions* Multi PERCT technology into an industrial pilot production of a Chinese cell manufacturer.This technology upgrade is an alternative to boost existing multi crystalline solar cell production above 18% based on standard mass production equipment and standard quality wafers.The process sequence utilizes mass production equipment used for manufacturing standard screen printed full area Al-BSF solar cells.In addition, the rear side is passivated using standard PECVD equipment and prior to this step it has been totally diffused (PERCT) with a cost effective boron diffusion using BBr3 utilizing an upgraded standard diffusion tool.Furthermore, a laser is used to open the rear side contacts prior to screen printing of the metallization.
