摘要：

On illumination, selenium deposited on nanoporous n-TiO2 transfers photogenerated electrons into TiO2. When p-CuCNS is coated on top of the selenium deposited on nanoporous n-TiO2, holes are directed into the p-CuCNS. A photovoltaic cell of nanoporous n-TiO2/selenium/p-CuCNS based on the above charge transfer process generates a photocurrent of similar to 3.0 mA cm(-2) and a photovoltage of similar to 600 mV at 800 W m(-2) simulated sunlight. The efficiency of the cell seems to be limited by surface recombination and the presence of voids in the TiO2 film. Photoelectrochemical experiments also indicate that when selenium is deposited on nanoporous n-TiO2 photogenerated electrons in selenium are efficiently transferred to TiO2.
