Technology Description:

Tandem PV will develop and test an advanced processing tool that integrates high-throughput solution deposition and precise drying to deposit large-area perovskite thin films of exceptional optical and electronic quality. Production of these films on large areas is a critical step towards perovskite-Si tandem PV cells that can achieve significantly higher efficiency than traditional Si PV cells. Small-scale perovskite PV device fabrication typically occurs using a spin-coating process, but the process is not easily scalable. The ability to deposit perovskite PV devices with a large-scale production technique while achieving the same quality and stability achieved by record-setting spin-coated laboratory cells would be a significant step forward. If the project is successful, it will remove a major obstacle to the successful commercialization of perovskite PVs.
