Given that solar cells are fundamentally opto-electronic devices, understanding the optical properties of the constituent materials is critical for engineering and optimizing photovoltaic performance.聽 Here at PVIC we have a large group of researchers deeply involved in accurate optical measurements through a variety of techniques.聽 We specialize in spectroscopic ellipsometry and have ellipsometric instrumentation capable of measuring spectral ranges from millimeter to vacuum-ultraviolet wavelengths.聽 Additionally, have capabilities in transmittance and reflectance spectroscopy as well as photothermal deflection spectroscopy.聽 The results of such optical measurements are used for a variety of purposes such as solar cell performance simulation, real-time material degradation studies, optical Hall effect determination of electronic properties, measurement of opto-electronic anisotropy, real-time thin film growth monitoring, and many more.聽 Click on the slides to learn more about these projects.
