目:Perovskite Solar Cells with High Stability and High Efficiency

时间:2019716日(周1000

地点:理学楼308

报告内容简介:

Considering recent energy demand, it is obvious that the development of renewable energy sources and high efficient devices are indispensable. Solar cells are believed to be very promising to replace fossil energy to solve the energy crisis. Perovskite solar cells (PSCs) is very promising to dominate solar cell market due to their high efficiency. However, it is still challenging to prepare PSCs with high efficiency and high stability, for outdoor applications. Structure engineering including interface layer manipulation and nanoparticle incorporation are used to improve the stability and efficiency of PSCs. Moisture stability of the devices are improved by hydrophobic layer induced into PSCs. UV light stability is enhanced by light converter, which can convert UV light into visible light. The converted light will be used by devices to achieve a higher efficiency. Metallic nanostructures are introduced into devices to increase the optical path length of the incident light leading to improved light harvesting and increased device performance. PSC efficiency was improved to 21% by structure engineering, which is very promising for practical applications. Solar energy storage effect is also obtained by integrating afterglow fluorescence nanomaterials into PSC devices to realize solar cells working in dark conditions.
