Overview
- Researchers at The Hong Kong Polytechnic University published a peer‑reviewed review in Nature Photonics that outlines how to transition perovskite/silicon tandem devices into market-ready solar modules.
- The plan seeks to lift conversion efficiency from about 34% toward roughly 40% by guiding materials choices and manufacturable processes.
- Because certified long‑term reliability data are scarce despite early outdoor trials, the authors recommend accelerated stability testing aligned with International Electrotechnical Commission protocols.
- The review highlights core barriers such as perovskite instability under moisture, oxygen, ultraviolet exposure and temperature swings, and the need to solve uniformity, defect control and large‑area fabrication for module scale.
- The team urges sustainable strategies for lead and rare elements plus coordinated industry–academia programs tied to carbon‑neutrality goals; a separate CityUHK study reports perovskite cells with strong thermal durability, signaling progress on stability.
