Nanoscale Characterization of Emerging Photovoltaic Materials and Devices
Prof. Yoon is an Associate professor of ECE at the University of Utah. Her research focuses on nanofabrication and characterizations of solar energy materials and devices.
Emerging photovoltaic devices offer the promise of higher performance and lower cost than traditional Si planar solar cells. However, characterizing new devices can be challenging due to their complex structures and non-uniform microstructural properties. Electron-beam (e-beam) probes are powerful tools that can be used to measure the local inhomogeneity of PV materials and devices on the nanoscale. We will review the state-of-the-art metrology for emerging PV devices, focusing on e-beam probes. We will cover the following topics: (i) microstructural characteristics of emerging solar cells, (ii) case studies of using e-beam probes to investigate the nanoscale properties of PV devices, (iii) feasibility of e-beam probe metrology for other optoelectronics and semiconductor devices.
This session will be of interest to researchers and engineers working in the field of emerging solar cells and diverse optoelectronic devices.
