Low-cost, High Efficiency, and Flexible Perovskite Solar Modules by Fast Blade Coating

Perotech demonstrated a record efficiency perovskite minimodules in Phase using a more stable FACs-perovskite ink formulation which showed record long stability among all reported perovskite modules. In Phase II base and the option periods, Perotech will work with UNC team to develop flexible perovskite modules with efficiency, stability and cost that meet Navy application needs. The team will address a series of technical challenges identified by 1) scaling up the coating of multiple layers including perovskites and charge transport layers by continuous deposition process on flexible substrates, 2) reducing cell-to-module efficiency loss using advanced module structure combined with new laser scribing tools and methods; 3) addressing new degradation mechanism in perovskite modules which do not exist in cells, and 4) developing encapsulation and packaging of flexible solar modules with low cost. The project will involve a broad spectrum of innovations involving ink formulation, device design, and fabrication methods This project will leverage the US-MAP program led by NREL and facility at NRL on the measurement of efficiency as well as environmental stability of perovskite modules.
