Abstract: A photovoltaic device includes a substrate, a semiconductor stack and a transparent tunnel junction. The semiconductor stack includes an n-type layer selected from a first transparent conductive oxide layer, or a window layer, or both; and a p-type absorber layer disposed on the n-type layer, wherein the absorber layer consists essentially of CdSexTe(1-x), wherein x is from 1 to about 40 at. %. The transparent tunnel junction comprises a transparent interface layer of CdyZn(1-y)Te doped to be p+type, and a transparent contact layer doped to be n+type, and the interface layer is disposed between the p-type absorber layer and the transparent contact layer. In bifacial embodiments, the tunnel junction forms a transparent back contact and electrode; and in multi-junction embodiments, the tunnel junction forms a diode-like connector between top and bottom cells. The transparent contact layer may comprise tin oxide or zinc oxide doped with aluminum, fluorine or indium.

Abstract: The invention relates to a thin film solar module comprising a monolithic solar cell array (1), including a plurality of solar cells (2) with a layer structure, comprising a rear contact layer (3), a front contact layer (4) and an absorber layer between the rear contact layer and the front contact layer, and an electrical connection structure (6) for electrically serially connecting neighbouring solar cells. The invention also relates to an associated production method. In the thin film solar module according to the invention, the electrical connection structure includes contact strips (7) for electrically serially connecting neighbouring solar cells, wherein the electrical connection structure electrically serially connects two respective solar cells (2m, 2m+1) that are adjacent to one another in a series connection direction (RS) via one or more contact strips (7). The contact strips run spaced apart from one another and transverse to the series connection direction with a direction component in the series connection direction in connection strip regions (8) of the solar cells. Each contact strip contacts a side (3a) of the rear contact layer of the one solar cell facing an absorber layer and a side (4b) of the front contact layer of the other solar cell facing away from an absorber layer, wherein the connection strip regions of the solar cells have connection recesses (9) in the front contact layer and the absorber layer for exposing the side of the rear contact layer facing the absorber layer. The invention also relates to the use of same in thin film solar cell technology.
