A new joint venture research work at Stanford and SLAC National Accelerator Laboratory, supported by Department of Energy and DARPA has come up with a new solar energy conversion process that can potentially double the efficiency of solar cells. Stanford engineers have discovered this new and totally different process to harvest energy from sun.

The best way to increase the efficiency of the solar cells is to somehow harvest the wasted heat energy and to keep up and utilize the high temperatures which are reached during conversion. Utilizing the existing technology along with utilizing both the photovoltaic and thermal conversion techniques is what is needed.

In the new process, the semiconducting material was coated with a thin layer of caesium which allowed the material to use both the light and heat of sun to generate electricity. Though this is not actually standardized photovoltaic mechanism happening, this is a photovoltaic-like response happening best at very high temperatures. The new process is called Photon enhanced thermionic emission (PETE).
