Abstract
A photovoltaic device having an increased open circuit voltage includes a body of semiconductor material between layers of opposite conductivity type, one of which has a wide bandgap energy and through which light enters the device. The body includes a first region closest to the wide bandgap layer and a second region with the bandgap energy of the first region being greater than that of the second region and less than or equal to that of the wide bandgap layer.
