Fabrication of c-Si HIT solar cells by PECVD
| Resumo: | This dissertation had the objective of fabricating HIT solar cells. These solar cells are composed of amorphous silicon layers, doped and intrinsic, with thicknesses at the nanometer scale, deposited in a silicon wafer’s surface. The amorphous silicon layers used in these solar cells were produced in the PECVD system from Material Science Department using low temperatures (200ºC). Their properties were optimized, studying the effect of factors such as doping gas flows and deposition pressures in these properties. Once optimized, the amorphous silicon with the best properties were used in the fabrication of the solar cells. The thickness of the layers was also studied with the goal to optimize the efficiency of the HIT solar cells. This work is part of the research project: FLEXSOLAR - Highly Efficient and Flexible Thin Film Epitaxial Silicon / Perovskite Tandem Solar Cells. |
