UVF demonstrates the ability to indicate differences in polymer types and degradation states in backsheets and encapsulation materials of PV modules.

Combinations of UVF with vibrational spectroscopies allow the polymer BoMs to be recognized and correlated with aging phenomena such as metal corrosion or potential induced degradation. UVF imaging can also be used for conventional visualization of nonmaterial-related anomalies, such as hot cells or cell cracks. The low purchase cost of the equipment makes UVF an affordable and high-throughput diagnostic method yielding comprehensive information that would otherwise only be accessible by combining several slower and more laborious methods.

However, recoding multiple current voltage curves (<i>IV</i> curves) under different red- and blueshifted spectra relative to the AM1.5g reference spectrum is time-consuming. Herein, a new method is suggested to quickly test solar cells for current mismatch. A solar simulator with two lasers instead of multiple LEDs is used, so that two monitor diodes can track intensity changes of each light source during the measurement. Postmeasurement corrections can be applied using this data, circumventing long stabilization times of the solar simulator. To minimize the scan time, it is focused only on determining the correct short-circuit current and not the full <i>IV</i> curve.

The recombination lifetime is a commonly used tool, as it directly affects the current–voltage curve via the diffusion length. The lifetime is often estimated using time-domain measurement methods such as time-resolved photoluminescence. However, two obstacles emerge when applying the transiently measured decay times to the steady-state theory. In general, the decay time depends on the charge carrier concentration, and it is often not clear under which conditions the transient measurement must be conducted to be comparable with the steady-state performance of the device. Furthermore, diffusion and capacitive effects due to charge injection and extraction can influence transient techniques and cause the measured decay time to deviate from the sought-after recombination lifetime. Voltage-dependent steady-state photoluminescence measurements can be used to estimate the internal voltage during device operation and allow the extraction of collection efficiencies and effective steady-state decay times that are independent of transport and capacitive effects.
