Perovskite Tandem Solar Cells – ScienceDaily

Scientists from the University of Surrey have shown the significant improvements in perovskite-based solar cells.

Perovskite solar cells have shown significant potential for reaching the efficiency frontier of the widely used solar cells currently on the market by absorbing light in a wider range of wavelengths. The industry has paid great attention to the development of perovskite-based cells thanks to their inexpensive and simple manufacture, and their efficient combination with other types of solar cells to make tandems.

Perovskite solar cells have emerged as the legacy of silicon-based solar cells because of their high energy conversion efficiency, low development costs, and their ability to be ultra-light. Perovskites, named after a naturally occurring mineral that has a structurally similar chemical formula, are synthetic composite materials with three-dimensional lattice crystal structures.

In a cover published by the American Chemical Society’s top journal Chemical Reviews, the Surrey Advanced Technology Institute (ATI) team summarizes recent advances in improving the energy conversion efficiency of tandem perovskite solar cells, including customization the thickness of perovskite and the improvement of the transparency of perovskite solar cells, more effective protective layers and much more. The team also sheds light on metrology, large-scale manufacturing, commercialization development, and lead-related environmental issues.

In the paper, the team provides a roadmap for further progress, including strategies to improve energy conversion efficiency, stability and reliability assessments, and potential applications.

Dr. Wei Zhang, the corresponding author and lecturer in power technology at ATI, said, “Perovskite tandem solar cells are at the forefront of next-generation photovoltaic technologies. Our timely review summarizes the fundamentals of this exciting field of research and future applications. that the marketing of this inexpensive and highly efficient photovoltaic product as the main competitor of traditional crystalline silicon solar cells will be accelerated in the next few years. “

Professor Hui Li, First Author and Visiting Professor and Advanced Newton Fellow at ATI, said, “We are pleased to offer this report, which shows great potential for moving our planet towards green energy.”

Professor Ravi Silva, Director of ATI at the University of Surrey, said, “We are delighted that this wonderful research is finally being applied to real world applications and look forward to continuing our collaboration on perovskite tandem solar cells, which is research Priority area at ATI. “
