Scientists at Dongguk University have found a way to create printed p-channel thin-film transistors by using the abundantly available and environmentally-friendly copper(I) iodide semiconductor at room temperature. Their energy-efficient and cost-effective fabrication method for these transistors may pave the way for developing low-cost and novel optoelectronic devices.

In the development of photovoltaic technologies, Concentrator Photovoltaics (CPV) has so far achieved the highest efficiency for the conversion of sunlight into electricity. The basis for this latest achievement depends on special multi-junction solar cells as well as the ideal interplay between the cell and the module optics.
