Thin film polycrystalline silicon solar cells studied by transient terahertz probe spectroscopy
Original language description
Thin film polycrystalline silicon (poly-Si) solar cells were annealed in hydrogen plasma or in water vapour to suppress electrical activity of defects and impurities. The passivation procedure was optimized by higher hydrogen pressure of 300 Pa and keeping bias voltage Vbias constant during the whole passivation process. The plasma hydrogenation process was run as a closed system (without hydrogen flow) and the achieved passivation results (up to 497 mV) were close to the limit for poly-Si (500 mV). Passivated samples were analyzed by transient terahertz probe spectroscopy and Suns-VOC method to measure a solar cell's charge carrier lifetime and its open-circuit voltage VOC. A correlation of these measured parameters was observed. The transient terahertz probe spectroscopy appears to be a useful tool for a contactless investigation of materials where ultrafast processes of ns-long lifetimes play a crucial role, e.g. nanostructured objects and materials.
