新突破！这一技术让规模化生产钙钛矿光伏组件有望实现

Core Insights - The research team has made a breakthrough in the field of interface engineering for perovskite solar cells, introducing a novel "solvated crystal pre-seed" strategy that offers new hope for efficient and scalable production of perovskite photovoltaic modules [1][2] Group 1: Research Breakthrough - The "crystal-solvated pre-seed" (CSV) method involves depositing a specially designed low-dimensional halide solvated crystal layer on the substrate, serving as a "seed" for the growth of perovskite films [2] - This strategy has led to the construction of a dense, flat, and well-oriented high-quality active layer at the bottom of the perovskite film, fundamentally eliminating common defects such as voids and deep grain boundaries at the buried interface [2] Group 2: Industrial Application - The research team combined the CSV method with a scalable "slot-die coating" process, successfully producing a perovskite solar micro-module with a light-absorbing area of 49.91 cm² and achieving a certified efficiency of 23.15% [2] - The efficiency loss rate from small laboratory cells to larger area modules is less than 3%, demonstrating excellent scalability and uniformity control [2] Group 3: Future Implications - This research is expected to accelerate the commercialization of perovskite photovoltaic technology in various fields, including building-integrated photovoltaics, wearable electronics, and new energy vehicles, injecting new technological momentum into the future development of clean energy [3]
