Scientists from Tokai University have developed new optical technologies that can help electronic devices using optical connections to keep up with the demand of modern technology - such as for devices to be as small as possible, but more efficient. In a multi-collaboration, the scientists presented their range of methods and prototypes for optics to be smoothly integrated into electronics.

Researchers at Tokai University report in Nano Letters a systematic study on the effects that using different forms of titanium oxide in planar perovskite solar cells has on the performance of the devices. Perovskite solar cells, with a current maximum power-conversion efficiency of 23%, hold much promise for producing photovoltaic energy through devices that are easy and inexpensive to fabricate.
