New PV Cell Generates Electricity From UV, Visible, Infrared Lights
The PV cell prototyped at the Kyoto Institute of Technology by adding cobalt to a p-type GaN thin film and laminating an n-type material (right). The cell with an absorbing layer measures 10 x 10mm. The surrounding thin rectangular patterns are electrodes. And the p-type GaN thin film without cobalt (left).
