Abstract
A scribed photovoltaic device, comprising a photovoltaic device configured for generating electrical energy responsive to receiving solar radiation, the photovoltaic device comprising a plurality of electrically connected photovoltaic sections comprising a photovoltaic light absorbing chalcopyrite semiconductor region (“PLACS region”) disposed between first and second electrode regions. The photovoltaic sections can each comprise a scribe channel extending along and into two of the regions, wherein the scribe channel can comprise a pair of spaced opposing sidewalls of one of the regions, a pair of terraces comprising a pair of spaced opposing terrace shoulders, and a second pair of spaced opposing sidewalls of another one of the regions, with the spacing of the second pair of sidewalls being different than the spacing of the first pair of sidewalls. The spacing of the second pair of sidewalls can be less than the spacing of the first pair of sidewalls, and another one of the regions comprises the PLACS region.
