What our partners say
“We have observed that fullerene-based materials are the mechanical weak link… The use of Tinfab has completely overcome these challenges by providing a more mechanically robust interface (increasing fracture energy by a factor of ~5X). I see Tinfab as a necessary component for the commercialization of perovskite photovoltaics.”
