𝗣𝗲𝗿𝗼𝘃𝘀𝗸𝗶𝘁𝗲 𝗕𝗶𝗴-𝗠𝗮𝗰 🍔 An HZB team has now developed a triple-junction solar cell using three different perovskites and a novel graphene oxide/self-assembled monolayer (GO/SAM) bilayer as the hole conductor. The result: 27.3% efficiency and virtually no performance loss after more than 770 hours of operation. Published in Joule, the study also suggests that further improvements could push this architecture beyond 30%.
