Abstract:
1. A method of fabricating monolithically-integrated optoelectronic modules comprising at least two series-interconnected optoelectronic components, comprising the steps of: cutting at least one continuous back-contact groove into a back-contact layer, wherein cutting the at least one continuous back-contact groove forms at least one first and at least one second back-contact component that are electrically disconnected from each other; cutting at least one continuous front-contact groove into a front-contact layer to form at least one first and at least one second front-contact components that are electrically disconnected from each other, and wherein at least a portion of the at least one first or the at least one second front-contact components overlap with the at least one second or first back contact components, respectively; forming at least one semiconductive layer that comprises at least one semiconductive optoelectronically active layer, wherein a portion of the at least one semiconductive layer is disposed between the front-contact layer and the back-contact layer, and the semiconductive optoelectronically active layer comprises a CIGS-type ABC drilling at least one cell-to-cell via hole, wherein the drilling the at least one cell-to-cell via hole and the cutting the at least one continuous front-contact groove are performed after the front contact layer, the semiconductive layer and the back contact layer are formed, and wherein heat provided in the drilling process causes:
