Description

Investigation of Materials Degradation in Concentrating Photovoltaic Systems and Spectroradiometry Solutions for Weathering and Solar Simulators Investigation of Materials Degradation in Concentrating Photovoltaic Systems and Spectroradiometry Solutions for Weathering and Solar Simulators We propose to carry out a systematic study of materials reliability for CPV systems. We also propose to investigate solutions for a built-in spectroradiometry system to monitor the spectral distribution of the illumination source used in the study. The MBE Optoelectronics Group is currently developing ultrahigh efficiency multijunction solar cells using a new, innovative approach to achieve record-breaking efficiency. The group has a rich background in the measurement of optoelectronic devices and materials and they are interested to use this expertise to study the reliability of CPV systems. The spectral distribution of the illumination source used in materials degradation study and its match to the suns spectrum is important and becomes even more crucial for materials which will be used under concentrated sunlight. Dr. OBrien and the principal investigator, Prof. Zhang, have a strong background in spectroscopic systems and will work to evaluate a cost-effective means to monitor spectral irradiance of the illumination source used during weathering of materials. A systematic study of CPV materials will be carried out in at specified exposure intervals. Comparison will be made between degradation under un-concentrated and concentrated sunlight, in order to discover additional considerations which may be necessary in the design of CPV materials and devices. Built-in spectroradiometry solutions will also be evaluated.
