nTact, is pleased to announce the National Science Foundation has awarded us an SBIR Phase I grant for “Scalable fabrication of stable perovskite solar panels using slot-die coating technique.” As a continuation of Phase 1, this STTR Phase II project proposes to commercialize Perovskite PV technology by developing a reliable, reproducible, and cost-effective upscaled version of perovskite photovoltaic (PV) devices using nTact’s industry-proven slot-die coating technique, to ultimately produce rigid and. flexible, highly efficient perovskite solar cells (PSC).
The efficiency of perovskite solar cells has surged to over 22% in recent research and now rivals that of CdTe, and Si-based solar panels. Most research lab perovskite solar cell devices are fabricated via spin casting and have a device area of less 1 sq. cm. Despite the progress of perovskite solar cell technology, three fundamental issues need to be addressed for commercialization: device lifetime, controllable perovskite deposition, and improved manufacturing, especially in the area of scalability. This project’s objectives are to: 1) produce a hybrid perovskite (HP) slot-die deposition solution for large solar panels sized 600-1200 mm and beyond, 2) build slot-die coating solution for perovskite-silicon tandem photovoltaic cells, and 3) conduct modeling and reliability studies to optimize the system.
