Understanding the Device Physics of Organic Solar Cells through Low Temperature Measurements
thesisposted on 09.03.2022, 03:53 by YAHUI TANG
While the record efficiency of organic solar cells reaches 18% due to the development of non-fullerene materials, little agreement has been achieved on the mechanisms behind the success. This project, therefore, investigated the device physics in these new-generation organic solar cells, mainly through low-temperature device measurements. Through this project, significant advances in understanding the device physics of organic solar cells have been made, with the critical role that temperature plays in the operation of non-fullerene based organic solar cells highlighted. The findings of this thesis potentially pave a pathway towards a better design of organic photovoltaic materials and devices.
