A tandem solar module includes first and second thin film solar cell circuits and a transparent coupling layer disposed between the first and second thin film circuits for securing the first and second thin film circuits together in a stack. Each solar cell circuit includes a multi-layer structure, the multi-layer structure including a substrate, a first conductive layer formed over the substrate, a buffer layer, an absorber layer formed between the first conductive layer and the buffer layer, and a second conductive layer formed over the buffer layer. The first thin film solar cell circuit and second thin film solar cell circuit are oriented with respect to one another such that the absorber layers are disposed between the substrates of the circuits. The first and second solar cell circuits have different bandgap profiles. |

1. A tandem solar module comprising:
a first thin film solar cell circuit comprising one or more thin film solar cells; a second thin film solar cell circuit disposed underneath said first thin film solar cell circuit and comprising one or more thin film solar cells; and a transparent coupling layer disposed between the first and second thin film circuits and securing said first and second thin film circuits together in a stack, wherein each solar cell circuit comprises a multi-layer structure, the multi-layer structure including a substrate, a first conductive layer formed over the substrate, a buffer layer, an absorber layer formed between the first conductive layer and the buffer layer, and a second conductive layer formed over the buffer layer, wherein the first thin film solar cell circuit and second thin film solar cell circuit are oriented with respect to one another such that the absorber layers are disposed between the substrates of the circuits, wherein the first and second solar cell circuits have different bandgap profiles. |
