Abstract

A solar PV module is disclosed having two types of laterally-separated coplanar cells with different bandgaps to improve conversion efficiency. A diffracting entrance window directs sunlight with wavelengths shorter than a separation 5 wavelength ks is directed largely to the first type of wider bandgap cells. Sunlight with wavelengths longer than a separation wavelength ks is directed largely to the second type of narrower bandgap cells. The separation wavelength is chosen so that each cell is illuminated largely by that part of the solar spectrum to which it has the higher conversion efficiency, resulting in an overall conversion efficiency higher than 10 for either type of cell used alone. The wider bandgap cells are configured on a planar support in separated parallel strips, with the narrower bandgap cells largely filling the area between these strips.
