Researchers at Peking University have fabricated several photovoltaic devices on single CdS nanobelts. The output power can be multiplied by connecting two or more of the Schottky junction photovoltaic devices in parallel or in series.

The study demonstrates that the 1D Schottky junction photovoltaic devices, with the merits of low cost, easy fabrication and material universality, can be an important candidate for power sources in nano-optoelectronic systems.

The researchers presented their work in Nanotechnology.
