Abstract
A device and a method for its fabrication. The device may include a first surface, a second surface to receive light into the device, a first photovoltaic cell between the first surface and the second surface, and a second photovoltaic cell between the first surface and the second surface. The first photovoltaic cell includes a first region of a first photovoltaic material exhibiting an excess of a first type of charge carrier and a second region of the first photovoltaic material exhibiting an excess of a second type of charge carrier, and the second photovoltaic cell includes a first region of a second photovoltaic material exhibiting an excess of the first type of charge carrier and a second region of the second photovoltaic material exhibiting an excess of the second type of charge carrier.A first contact is electrically connected to the second region of the first photovoltaic material, a second contact is electrically connected to the first region of the first photovoltaic material, and a third contact is electrically connected to the first region of the second photovoltaic material. The first surface is between at least a portion of the first contact and the second region of the first photovoltaic material, and the first surface is between at least a portion of the second contact and the second region of the first photovoltaic material.
