Method for Fabricating Epitaxial Halide Perovskite Films and Devices

詳細技術說明

Executive Summary Perovskite crystal structures allow for a transformation in the field of electronic and solar power harvesting devices. Specifically these transparent halide perovskites are able to be grown as a thin film through a process known as epitaxy and can be utilized to store light energy. Description of Technology Improving efficiencies are making halide perovskite materials competitive with silicon in solar and semiconductor applications. The technology developed at Michigan State University allows for high crystalline ordering via the epitaxy process thereby generating thin, transparent films with enhanced crystalline orientation. Specific substitutions can also be made to the halide perovskites such as tin for lead which in turn decreases the toxicity of the device. The enhanced thin film produced from epitaxy could lead to far reaching advances in the field of compound semiconductors as well as photovoltaic devices. Key BenefitsBetter crystal orientation compared to single crystal or amorphous crystalLess toxicInorganic alternatives would increase stabilityCan be applied as a thin film versus generation of a full panel deviceNovel method of generating thin film quantum wellsAbility to create multi-layer quantum wellsModulation of quantum wells via stoichiometry ApplicationsPhotovoltaic devicesSolar roofs/solar shinglesCoatings for glassCompound semiconductorsLight-emitting diodes (LED)TransistorsSolar cellsHigh-Powered ElectronicsQuantum computingHigh-energy telescopesLasers Patent Status Patent pending Licensing Rights Available Full licensing rights available  Inventors: Richard Lunt, Lili Wang, Pei Chen Tech ID: TEC2017-0100
