Abstract
A monolithic multijunction photovoltaic device is disclosed which comprises two or more photovoltaic cells between two surfaces. Each of the photovoltaic cell materials include a first region exhibiting an excess of a first charge carrier and a second region exhibiting an excess of a second charge carrier. Contacts are connected to the regions of the photovoltaic cells in configurations that allow excess current to be extracted as useful energy. In one embodiment, a first contact is electrically connected to a second region of a first material, a second contact is electrically connected to a first region of the first material, a third contact is electrically connected to a first region of a second material, and a fourth contact is electrically connected to a third material. In other embodiments, the contacts may be positioned on the surfaces of the monolithic device to minimize shadowing.
