报告题目: Chemical Additive-Enabled Advancements for Perovskite Photovoltaic and Semiconductor Manufacturing

报告摘要: My research focuses on the development of new electrochemical technology for ionic thermoelectric, perovskite photovoltaic, and semiconductor manufacturing. This talk will be divided into two parts. Firstly, further improvements in perovskite solar cells require better control of ionic defects in the perovskite photoactive layer during the manufacturing stage and their usage. Therefore, various passivation strategies have been developed to improve the reliability. However, most of the traditional passivators interact with ionic defects and are then confined to certain locations after the manufacturing stage, making it difficult to passivate newly generated defects during device operation and storage. In this talk, I will discuss recent progress in developing “living passivator” that can be activated by environmental stresses and continuously release new passivators to ensure the stability of perovskite solar cells. Secondly, we developed effective additives for the fabrication of nanocrystalline copper with uniform nanograin sizes and low impurity levels, which enables fast grain growth and facilitates cross-interface Cu-to-Cu bonding at low temperatures. The combination of a low thermal budget and superior bonding quality offers a promising approach for the development of fast and low-temperature bonding processes for advanced electronic and 3DIC packaging applications.
