Abstract :
During carrying out a project on high efficiency crystalline silicon solar cells, different materials (CZ and FZ wafers with different resistivities) and different structures were experimented upon. For improving solar cell performance, the technology of emitter passivation, AR surface texture and coating, HCl cleaning of the quartz tube, etc., were used. The best efficiency obtained to date is 18.2%
