(1) Project: Smart solar cells, self-responsive to the sunlight and balancing indoor shading and electricity harvesting in different time of a day.• Synthesis of new materials by modifying fullerene with a photo-isomeric chemical groups.• Collaborated with professors and companies to find available photochromic materials.• Design the device structure for smart solar cell based on different materials.(2) Building up new lab for state key laboratory. Design and build a new lab for metallic oxide deposition and characteristics. Responsible for building up super-clean room, bidding and setting up magnetron sputtering system, and electricity and gas reconstruction.(3) Developed a MATLAB program to calculation the electric field distribution in multi-layered devices based on transmission matrix model. The simulation results helped to optimize the device structure and analyze the optical parameters in planar-structured device and led to a published work.
