The Solar Energy Laboratory is an interdisciplinary research lab supporting the photovoltaic and related research from basic materials science to device and system development. Our research activities include photovoltaic material science, optoelectronic device physics and bio-incorporated electronics, and flexible solar cell modules. The solar energy laboratory consists of world-class facilities for solar cell material synthesis, material characterization, and device fabrication and characterization. The lab is equipped with necessary equipment to perform the photophysical and electronic characterizations of semiconductors, especially for solar cell materials such as conjugated polymer and halide perovskite.
- Chemical and nanomaterials synthesis, including thin films by using different chemical routes, such as sol-gel, hydrothermal, spin coating, and electrospray, under specific conditions
- Physical deposition of thin films by using thermal evaporation system, including metal films and oxide semiconductor films
- Photovoltaic and electronic devices fabrication, including perovskite solar cell, dye sensitized solar cell, organic solar cell, and photodetector device fabrication and performance measurement
- Optical properties and charge carrier dynamics with UV-vis absorption and transmittance spectra for solution and solid thin film samples. The lab can examine the dynamics of excitons and charge carriers through steadystate and time-resolved photoluminescence spectroscopy, and laser-induced transient absorption and emission decay kinetic.
- Solar cell conversion efficiency measurement system consisting of a 3A solar simulator and source measure unit
