Kempe reported that to test UV ageing in an environmental chamber for doses equivalent to 20 years of exposure is about six months. However, it is required to find a method to test the PV module (Kempe, 2008) in a shorter time period. Researchers are also trying to determine the suitable stress testing conditions for UV ageing of the PV modules.
It reached 4% after 4200 h of accelerated UV ageing for the most discoloured modules, while the UVID of the SHJ solar cells only accounted for a 3% loss. Furthermore, the destruction of UV absorbers is an issue affecting the integrity of the whole PV module and can lead to accelerated delamination, among other critical types of damage.
During the UV accelerated aging test, a set of solar cells was aged under open-circuit conditions and another one was submitted to a voltage of 0.550 V corresponding to the operating voltage of such solar cells at the maximum power point in STC.
This work presents the effect of UV accelerated aging test which is one of the most aggressive aging tests for silicon solar cells, on monocrystalline silicon solar cell properties.
The ageing temperature (83°C) and xenon lamp UV irradiance were selected according to the IEC TS 62788-7-2:2017 standard to provide a high acceleration of degradation kinetics. 16 The ageing test parameters (UV chamber, lamp type, UV irradiance, sample temperature, and atmosphere) corresponding to each module are presented in Table 1.
Liu et al. studied the effect of UV radiation on polymeric backsheet and reported that UV ageing time is insufficient in the PV module as per IEC test standards. They recommended a longer ageing time and higher UV radiation intensity for reliability testing of the PV module (Liu et al., 2014).
