Abstract:
1. A photovoltaic device comprising: a first energy absorbing element configured to convert energy from a photon impinging the first energy absorbing element into a first electrical current; and a second energy absorbing element being oriented with the first energy absorbing element in a non-parallel manner, the second energy absorbing element configured to convert energy from the photon impinging the second energy absorbing element into a second electrical current, the photon impinging the second energy absorbing element after the photon impinged the first energy absorbing element, each energy absorbing element having a top contact extending therealong, wherein a surface of the top contact extending along the first energy absorbing element is oriented in a non-parallel manner with a surface of the top contact extending along the second energy absorbing element, wherein the first energy absorbing element overlies a metallic core.
