题目：PV technology beyond silicon: the perovskite-Si tandem solar cells (后硅时代的光伏技术：钙钛矿/硅叠层太阳电池)
The cost of the leading crystalline silicon technology has reduced tremendously over the last 10 years due to economies of scale and policy-driven demand growth. The power conversion efficiency of single junction crystalline silicon solar cells has risen to a record value of 26.6%. The room for further efficiency-improvement becomes less and less because of the SQ limit. One widely explored path to overcome this limitation is to produce a tandem cell, by stacking the silicon solar cell with a wide-band gap partner. In this talk, we will show that the perovskite in tandem with silicon provides can make electricity more efficiently and economically. We will also review the recent progress of the perovskite/Si tandem solar cells and discuss their potentiality as a practical and sustainable solution to the challenge of meeting the increasing energy demand.
Keywords: silicon solar cells, perovskite, tandem structure.
Dr Guijun Li received his Bachelor degree and Master degree from Nankai University. He then studied with Professor Hoi-Sing Kwok at HKUST, where he received his PhD degree in ECE in 2016. From 2009 to 2012, he worked at BOE and then Astronergy. He joined PSKL of HKUST as a research associate after his graduation and then as an assistant professor of Shenzhen University in 2017. Dr.Guijun Li’s research interest is in the development and applications of optoelectronics with current emphasis on (1) photovoltaic devices, (2) light emitting devices based on quantum-dots and perovskite materials, (3) smart window. Dr.Guijun Li has published/co-authored more than 40 research papers and held more than 10 patents/patent applications.
