Project R-12262

Enabling flexible application integrated photovoltaics via thin film technology Subtitle: Industrially viable development of high performing flexible CIS photovoltaics (Research)

New and more environmentally friendly energy resources must be utilized to realize the decarbonization policies agreed upon in the 2015 Paris Agreement. Photovoltaic technologies already play a significant role and are predicted to have even a greater share in such a transition away from fossil-based fuels. In this framework, recent tandem solar cell technologies confidently promise performance levels relevant to modern terrestrial and extraterrestrial applications. Here, Perovskite- CuInSe double junction cells have the most significant potential among viable candidates in production costs, performance metrics, and technology maturity. Such lends this project an excellent valorization potential in that it can (help) enable vehicle and infrastructure photovoltaic integrated applications. This proposal offers scalable solutions to fabricate efficient CIS on flexible stainless-steel foils. Central to the idea of the project is the ability to translate results to industrially applicable settings. That is reflected in the choice of approach (Design of Experiment) and techniques employed. More technically, it is aimed to study and obtain (and present a) more in-depth understanding of the performance loss mechanisms existing in interfaces and layers and explore strategies to passivate them. These goals and outcomes, therefore, will benefit both industrial and scientific communities.
