Opportunities and challenges in the commercialisation of perovskite solar cells
Organic-inorganic hybrid perovskite solar cell is a new type of thin film photovoltaic technology and has achieved extraordinary improvements in power conversion efficiency in a relatively short time. It has potential to be made into a high efficiency, low cost alternative photovoltaic technology. The solution based system is attractive for processing of devices using a variety of techniques, such as printing and spraying, and it can be readily made into flexible solar cells on plastic substrates. It can also be manufactured by vacuum deposition at relatively low temperature. However, there are a number of challenges before the technology’s commercialisation, for example, difficulties in forming good quality large area thin films, device stability and lead poisoning etc. In this presentation, I will talk about some recent progress in dealing with these challenges and introduce activities in scaling up of perovskite solar cell modules.
Yi-Bing Cheng is a Thousand Talents professor at Wuhan University of Technology, China and an Adjunct professor in the Faculty of Engineering, Monash University, Australia. He is an elected Fellow of the Australian Academy of Technological Sciences and Engineering. He completed his undergraduate (1978) and Master (1983) studies at Wuhan University of Technology, China and received a PhD degree from University of Newcastle-upon-Tyne, U.K. in 1989. He was an academic staff at Monash University between October 1991 and March 2018. He specialises in inorganic materials. He is currently working on the development of perovskite solar cells.
Wuhan University of Technology (WUT) is one of the leading Chinese universities under the direct administration of the Ministry of Education. In the past 70 years, WUT has fostered over 500,000 engineers and technicians working mainly in the three industrial sectors: building materials industry, transportation industry and automobile industry. The University has 24 academic schools, 4 State Key Laboratories, 8 State key Disciplines, 77 Doctoral programs, 226 Master’s programs as well as 90 Bachelor’s programs. The University has about 55,000 students, including undergraduates, postgraduates, and international students. Besides, Material Science, Engineering Science and Chemistry rank the top 5‰ in the ESI (Essential Science Indicators) global discipline ranking list.
