To secure a firm European position for PSC module fabrication, ESPResSo will bring forward technological solutions that combine high-throughput, low-cost manufacture of efficient and long-lasting PSC PV modules that can also have seamless integration in application areas that require customised end-products. This new approach is different to c-Si products produced as low-cost commodity products in low-labour cost countries outside Europe, in that customized products can create a high added value that allows for local European production close to the end-user.

Therefore, within the three-year timeframe of the project the consortium targets substantial progress on cell efficiency, stability, and module process upscaling which enables to combine these results into a glass-based module result at TRL5 as a consolidated project outcome. Demonstration of such modules in a BIPV facade element, supported with outdoor test results, opens then the door for technology validation at TRL6, for a fully integrated product. 



How ESPResSo progresses along TRL scale



The ESPResSo project will additionally open up three more routes towards customization and facilitation of integration. Novel processes will be initiated in this project to allow transfer of the PSC technology from the glass-based platform to various flexible, plastic substrates. Additionally, novel interconnection schemes will be investigated with the One-Step Interconnect (OSI) technology to allow for easy variation in sizes and shapes of PSC modules. Options to realize semi-transparentdevice designs will be explored, for use as see-through PV modules for e.g. window integration or for tandem applications by stacking on top of existing (e.g. c-Si) PV technologies to boost the overall power conversion. It is targeted to bring these technologies to TRL4. Full technology validation of these novel routes in more specified applications will however need further developments also beyond the timeframe of this project.
