MIC process has a lot of advantage, including low-temperature, low-cost, simple, capable for large-scale production, and compatible with glass substrates. In this work, the thickness ratio of silicon to aluminum is 1:1 and the annealing temperature is 550℃ for the MIC of poly-Si films, while the annealing time has been varied. The poly-Si MIC results were characterized by FE-SEM, XRD, AES, and SIMS. The best MIC of poly-Si films was obtained with an annealing temperature of 550℃ and an annealing time of 6 hours. Thin film solar cell with p-type and n-type amorphous silicon films has been compared to the thin film solar cell with p-type polycrystalline silicon film by MIC and n-type amorphous silicon film in this work.
