Annealing of thin film polycrystalline silicon solar cells in water vapour
Pikna, Peter ; Fejfar, Antonín
Samples of thin film polycrystalline silicon solar cells prepared by the Company CSG Solar AG were treated in water vapour. Appearance of treated solar cells was very similar to samples etched in a solution of acids, which is commonly used to approach the bottom part of pn junction. No significant improvement of measured open-circuit voltage Voc was observed, but the etching effect of water vapour can determine the upper limit of temperature, pressure and treatment time for water vapour passivation. Novel approach for preparation of a depth profile to approach the bottom part of pn junction is proposed.
