AI Customer ServiceThis phenomenon can be induced either by injecting current into the photovoltaic module (Electroluminescence) or through optical excitation using an appropriate light source (Photoluminescence). This paper offers an overview of the conventional outdoor luminescence imaging technique, delving into its applications and limitations.
Photovoltaic (PV) cells convert the energy of solar or other light sources to electricity. The power conversion efficiency (PCE) of PV cells can be calculated by using Equation 1, where Pout is the maximum of the electrical output power density of a PV cell and Pin is the input light power density. PCE is the most important parameter of PV cells.
When a beam of parallel light is incident to a PV cell vertically, the illumination area can be well-defined by adopting an aperture mask with no need for considering the mask thickness.
Unlike EL or PL measurements, infrared thermography images can be easily obtained in a single shot while the PV array is operating under normal conditions. However, thermography inspections are limited to irradiance levels higher than 600–700 W/m 2 (Köntges et al., 2014; Weber et al., 2016).
However, the current approach has only been demonstrated in highly efficient SunPower interdigitated all back-contact (IBC) solar modules. The investigation with other types of PV modules becomes mandatory in order to consolidate the method as an inspection technique for solar PV power plants.
During the tracing of the current-voltage curve, the photovoltaic array changes its operating point from OC to SC, or vice versa. This provides two different points where the PL signal is high and low, respectively.
