A key pathway to meeting the Department of Energy SunShot 2020 goals is to reduce financing costs by improving investor confidence through improved photovoltaic (PV) module reliability. A comprehensive approach to further understand and improve PV reliability includes characterization techniques and modeling from module to atomic scale. Imaging techniques, which include photoluminescence, electroluminescence,...
Module performance can be characterized by imaging using baseline and periodic images to track defects and degradation. Both thermal images, which can be acquired during sunny operating conditions, and photoluminescence images, which could be acquired at night, can be collected without electrical connection. Electroluminescence (EL) images, which are useful to detect many types of defects such as...
Electroluminescence (EL) and light-beam-induced-current (LBIC) mapping are used to study lab-size thin-film photovoltaic devices. Inhomogeneities seen in individual cells with these two characterization techniques are compared and analyzed. Features of interest in CdTe cells include signal variations across large areas of the cell as well as local, well-defined regions with little or no EL signal...
Several camera imaging techniques have been applied to the characterization of Cu(In,Ga)Se2 (CIGS) solar cells having a range of efficiencies. Photoluminescence (PL) imaging shows brightness variations after the deposition of the CIGS layer that persist through CdS deposition and subsequent processing steps to finish the devices. PL and electroluminescence imaging on finished cells show a correlation...
