P-type multicrystalline-Si solar cells using blended SOLSILC silicon
conference paper
Blends of polycrystalline and SOLSILC silicon in multicrystalline p-type ingots were tested by solar cell processing. By comparing IV-parameters and Internal Quantum Efficiency of cells from p-type multicrystalline cells it was concluded that a minor cell performance reduction can be attributed to impurities. This can be significantly improved by emitter optimization or an extra cleaning step. In this manner, a cell efficiency of 16.4% was obtained for both 25% blend and reference.
