Company Profile

Tandem PV (originally dba Iris PV) was formed around development of tandem photovoltaic cells comprised of a metal-halide perovskite solar cell over a silicon-based cell. The firm has developed an advanced processing tool that integrates high-through-put 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 c/wouldremove a major obstacle to the successful commercialization of perovskite PVs.
