ZSW

The tandem structure as a whole in all prepared cells and modules outperformed individual cells or modules in terms of efficiency. This clearly demonstrates the superiority of tandem solar modules. ZSW now aims to further scale up and develop tandem thin-film technology in a joint effort with interested industry clients... Conventional silicon PV cells would appear to be the obvious choice for the bottom solar module. However, an even more interesting proposition is to use thin-film technologies exclusively. The bottom module can also be made of perovskite or of CIGS, which is the case in ZSW's module. CIGS is a mix of materials - copper, indium and gallium vapor-deposited onto a rigid or flexible substrate in a selenium atmosphere. The institute's experts and industry partners had developed this technology and ramped it up for mass production in earlier projects. CIGS's spectral absorption can be tailored to a perfect fit for the tandem composite... Copper indium gallium selenide..
