Employing NiO as a hole collector in solid-state dye-sensitized solar cell

Abstract

A solid-state dye sensitized solar cells (DSSC) comprising of p-type NiO thin layer on TiO2 was fabricated in which the dye is adsorbed on the p-type oxide and the thin NiO layer acts as a hole collector as well as a barrier for charge recombination. DSSC with NiO coated TiO2 electrode with Ru-dye delivers Isc = 0.15 mA and Voc = 480 mV. It was shown that the p-type oxide materials could be successfully used to construct DSSC and the plausible charge transfer mechanism is discussed.
