摘要：

Diffusion process on different temperatures and related effects on ideality factor (eta) and recombinations in solar cell have been investigated. Phosphorus-doped n+-emitters were fabricated by applying Spin-on doping (SOD). Dark current-voltage characterization has been used to investigate different recombinations and their relation with the ideality factor. Dark IV characteristics also revealed different current saturation limits at different diffusion furnace temperatures. Effect of doping temperature on sheet resistance helped to get optimized value at 950 degrees C to reduce carrier recombination and emitter recombination velocity in surface emitter layer. It was observed that there was strong dependency of sheet resistance over temperature in making n+-emitter layer of monocrystalline solar cells.
