Abstract

To make cost-effective solar cells, We have to use low cost material or make short process time or high temperature process. In solar cells, formation of emitter is basic and important technique according to build-up P-N junction. Diffusion process using spin-on dopants has all of this advantage. In this paper, We investigated n+ emitter formation spin-on dopants to apply crystalline silicon solar cells. We known variation of sheet resistance according to variation of temperature and single-crystalline and multi-crystalline silicon wafer using Honeywell P-8545 phosphorus spin-on dopants. We obtain uniformity of sheet resistance within 3~5% changing RPM of spin coater.
