Název v původním jazyce

Annealing of polycrystalline thin film silicon solar cells in water vapour at sub-atmospheric pressures

Popis výsledku v původním jazyce

Thin ?lm polycrystalline silicon (poly-Si) solar cells were annealed in water vapour at pressures below atmospheric pressure. The PN junction of the sample was contacted by measuring probes directly in the pressure chamber ?lled with steam during passivation. The Suns-VOC method and a Lock-in detector were used to monitor the e?ect of water vapour on VOC of the solar cell during the whole passivation process (in-situ). The open-circuit voltage of a solar cell at these temperatures is lower than at roomtemperature. Nevertheless, the voltage response of the solar cell to the light ?ash used during the Suns-VOC measurements was well observable. The temperature dependences for multicrystalline wafer-based and polycrystalline thin ?lm solar cells were measured and compared. In-situ observation proved that there was the required sensitivity to changing VOC at elevated temperatures during the process.
