Large-area dye solar modules are being developed at Fraunhofer ISE for application in photovoltaically active architectural glazing. Research is being conducted on transferring the production concepts to the new area of perovskite solar cells. We have demonstrated that modules can be produced with industrially relevant technology based on screen-printing and new sealing approaches. The 60 cm x 100 cm modules, with durable glass-frit sealing and internal series connection, can be fabricated reproducibly in cooperation with industrial partners. To this purpose, a special in situ coating method was optimized for perovskite solar cells, which requires very little material and can be easily upscaled.
