Abstract
Solar energy is the ultimate renewable energy source for human being for both clean and abundant. It is critical for solving global energy and the grand carbon neutral challenges. While crystalline silicon based solar cell has achieved enormous success, the pursue of printable solar technologies continue to be attractive to scientists with cost benefits and novel solar applications. Organic polymer photovoltaic cells (OPVs) and Hybrid organo-metal halide perovskite solar cells (PSCs) are two of the most promising candidates for next generation printable photovoltaic device primarily due to their high efficiency, printability, low cost and versatile form factors for application – flexible, colorful, transparency.
In this talk, I will present our work on OSCs and PSCs in the past decade. In OSCs, the research journey from understanding of bulk heterojunction OPV morphology to multicomponent OSCs, to various interface Engineering approaches which have played significant role in advancing the organic polymer solar cell technology, including invention of inverted solar cell structure, tandem polymer solar cells, transparent OSCs. Many of the know-hows have also been successfully applied in hybrid perovskite solar cell research. In this talk, I will discuss the application of organic semiconductors in stable PSCs, present the recent works using in-situ techniques to guide the development of high-performance PSCs using blade coating technique, novel electron transporting layer materials development and interfacial engineering work towards high efficient and stable perovskite solar cells.
