Academic lecture: Research on the stability of perovskite materials and their lead-free

Lecture Title: New Calcium-Titanium Ore Materials and Their Preparation for Optoelectronic Devices

Presenter:，Prof . Mingzhen Liu, University of Electronic Science and Technology of China

Lecture time: 15:00 on Thursday, September 17.

Lecture Venue: 301, School of Energy and Power Engineering

Lecture Content：

The research focuses on new optoelectronic materials and devices, especially in the field of photovoltaics, with a focus on solar cells based on organic-inorganic hybridization of new calcium titanate materials. These devices combine the functions of traditional solar cells with the excellent properties of the new materials, and have become a hotspot of international attention in recent years. This report will firstly focus on the current status quo and the major bottlenecks facing the development of calcareous titanium ore solar cells, explore the new calcareous titanium ore optoelectronic materials and their device preparation methods, reveal the deeper connotations of material physics, and highlight the current scientific research results, including new mechanisms leading the development direction of high-efficiency devices, new structures to break through device stability bottlenecks, new processes to promote the industrialization process, and so on. The preparation of calcium titanate materials and their practical application in optoelectronic devices provide new scientific connotations.
