Mechanical and Aerospace Engineering Research Team Publishes Research on Efficient Conversion of Solar Energy
Mechanical and Aerospace Engineering Professor Quinn Qiao and a research team from the College of Engineering and Computer Science recently published two papers in Advanced Materials, collaborations with Peking University and other universities in Europe. Both papers focus on the organic solar cell (OSC), which is a photovoltaic device that converts solar energy to electrical energy.
The first paper, “Quasi-Homojunction Organic Nonfullerene Photovoltaics Featuring Fundamentals Distinct from Bulk Heterojunction,” discusses the unconventional organic solar cell’s structure with more intrinsic charge generation and less charge recombination. The second paper, “Simultaneously Enhancing Exciton/Charge Transport in Organic Solar Cells by an Organoboron Additive,” provides a facile strategy of morphology optimization to improve the performance of OSCs. In both cases, the solar cell’s power conversion efficiencies (PCE) increase, which means they can convert solar energy to electrical energy more efficiently. Qiao’s group confirmed the mechanism of better performance for the solar cell from experiments.
The research was conducted at Qiao’s solar cell lab in Link Hall. An atomic force microscopy (AFM) was mainly used in the research to measure the current sensing AFM (C-AFM) data and an oscilloscope was used to obtain charge carrier dynamics data. The group has applied a patent for the measurement and has published many papers based on the technique in recent years.
