Interlayer Additives for Perovskite-based Photovoltaic Devices

Executive Summary Photovoltaic devices directly convert solar energy into direct current electricity.  Perovskite solar cells are receiving growing attention for large-scale commercial production..  Description of Technology Halide perovskite materials are a promising candidate for low-cost and efficient solar photovoltaic applications. A loss of stability can occur when crystal defects are formed during perovskite growth. This technology is a new method of developing highly efficient and stable perovskite-based photovoltaic devices. Key BenefitsImproved device stability: prevents formation of crystal defects that lead to loss in stabilityHigh efficiency: perovskite materials have a power conversion efficiency of over 20%Low cost: perovskite materials are used for the production of low cost photovoltaic devices ApplicationsDesign of photovoltaic devices Patent Status:   Patent Pending Licensing Rights Available Exclusive Rights Available. Inventors: Richard Lunt, Lili Wang Tech ID: TEC2016-0147
