ZnO/Si solar cell fabricated by spray pyrolysis technique

Abstract

The ZnO/Si heterojunctions have been prepared by depositing n-ZnO films doped with aluminium on p-Si by spray pyrolysis method. Heterojunction solar cells were fabricated using the configuration Al/ZnO/Si/In. The electrical properties of the heterojunction are investigated by means of current-voltage measurements in the temperature range 295-375 K. The cells show the rectifying behaviour characterized by the current-voltage (I-V) measurement under a dark condition, while photoelectric effects have been exhibited under the illumination. As a result, the conversion efficiency of the fabricated cell of about 6.6% was obtained. © Springer Science+Business Media, LLC 2006.
