Technology Features & Specifications
The central technology is the ligand-perovskite ink, which is based on nanoscience and coordination chemistry. The ligand stabilises the perovskite precursor through coordination and enhances the thin film quality during deposition by controlling the intermediate. The use of the ink depends on the fabricated device and the in-detail parameters can be customised, for instance, 500 nm thick film for high performance PV solar panels and 50-100 nm for LED devices.
Advantages include the low-cost raw material, printable technology, light weight, high energy conversion efficiency and switchable PV-LED functions. It can bring potentially great economic value with a reduced efficiency-stability-scalability-cost gap of PV/LED devices.
Potential Applications
The ink-based thin film technology is useful for new-generation PV/LED devices, such as flexible/portable devices, switchable PV/LED windows, smart buildings etc. Since perovskite PV technology is widely investigated by academic communities all over the world, the well-developed inks are also useful for the education/research sector with reduced entry level for junior researchers.
