Abstract
A photovoltaic assembly comprises a thin semiconductor lamina and a receiver element, where the receiver element serves as a superstrate in the completed device. The photovoltaic assembly includes a photovoltaic cell. The photovoltaic cell is a back-contact cell; photocurrent passes into and out of the back surface of the cell, but does not pass through the light-facing surface. The lamina is typically substantially crystalline and has a thickness less than about 100 microns, in some embodiments 10 microns or less.
