The efficiency of N-type perovskite tandem cell exceeds 27%
Aug 04, 2021
In recent years, independent perovskite cells have made rapid progress in conversion efficiency, and some cells have reached efficiencies of 25% or higher. So far, many cutting-edge R&D technologies have selected n-type or n-i-p cell structures for the perovskite layer. However, when it comes to making a series connection of perovskite and silicon-based bottom cells, the nip structure faces ma...
