Photovoltaic properties of cadmium selenide-titanyl phthalocyanine planar heterojunction devices

- CdSe/TiOPc cells harvest light practically in the whole visible range.
- Two mechanism of photogeneration of charge carriers are distinguished.
- Monomolecular recombination of free charge carriers is predominant.
- Relatively high fill factor under monochromatic illumination was obtained.
- Thickness optimization is required for the improvement of current density.

Photovoltaic phenomenon taking place in cadmium selenide (CdSe)/titanyl phthalocyanine (TiOPc) planar heterojunction devices is described. Mechanisms of free charge carrier generation and their recombination in the dark and under illumination are analyzed, chosen photovoltaic parameters are presented.
