The mechanism of the PID delay effect by UV light irradiation during PID test in p-type c-Si solar cells is proposed that the conductivity increase of the SiN x ARC layer under the 300–390 nm-wavelength UV light, which prevents or reduces many Na ions from penetrating the c-Si solar cell, slows down the degradation rate of the solar cell ...

SunsV OC measurements 1 2 are very similar to the J SC V OC measurements except that the SunsV OC uses a separate solar cell to monitor the illumination intensity rather than using the J SC of the solar cell. The monitor cell simplifies the measurement electronics since measuring cell voltage is much simpler than measuring the cell current.

When PV modules are exposed to the aforementioned external agents, they start to decay over time and reduce their efficiency. This occurs by solar panel frames corroding, glass and back-sheet delamination, and PV materials losing their properties, all of these cause the average 0.5% yearly degradation for PV modules.
