Tungsten Oxide Solar Cell

Research and application of solar cell is the focus of nowadays research on power field, how to improve the efficiency and lowering the cost are the two key problems of solar cell. The manufacturing cost of silica solar cell is too expensive which can not be widely applied. Nano TiO₂ solar cell has gradually replaced the traditional one. Its manufacturing cost is only the 1/5~1/10, the photoelectric efficiency is maintained at 10%, its service life can reach 20 years. But how to promote the conversion rate is always the focus of research.

Nano tungsten oxide material has the advantages like non toxic,harmless, easy to prepare, stable property, low price and fine visible light responsive, it is an ideal semiconductor photo anode material which is widely applied in photoelectrochemical field like photo degradation water, photo degradation organic pollutant and solar cell.

Photo anode material of dye-sensitized solar cell mostly uses TiO₂, the main reason is compared to ruthenium photochromics, TiO₂ is the best energy level of semiconductor. Tungsten oxide is the common used photo anode catalytic material of PEC photoelectrochemical cell. Compared to TiO₂ and ZnO (energy gap 3.4eV), it has smaller energy gap (2.5~2.8eV). Among which the perovskite structure will be easier to control by adjusting A and B site. So tungsten based oxide photo anode is a kind of material which has potential in photoelectrochemical solar cell anode.
