Borealis is an $8 billion revenue Austrian plastics company looking to serve the future perovskite market with its thermoplastic polyolefin (TPO) encapsulant. The special angle here is that the thermoplastic only needs low process temperatures, similar to those in perovskite manufacturing. We spoke to Geir Kristian Johnsen, Program Manager for Renewable Energy in the New Business Development department of Borealis. Degradation is one of the most important technical hurdles for perovskites to become a viable product. Degradation may even be the single most important challenge of all alongside large form-factor, scaled-up manufacturing processes, and power output per square meter. Within degradation, encapsulation and edge seals are going to be crucial. Perovskite is a lot more fragile than silicon, so the…
