As PID occurs at negative voltages for p-type cells [2] and at positive voltages for n-type IBC (Interdigitated Back Contact) cells [3] or n-PERT cells [5,7], PID can be prevented by grounding the system, respectively, at the negative and the positive connector/pole, thus preventing the degradation inducing system voltages. However, this solution is not possible …
First, PID of the depolarization type (PID-p) has been observed for bifacial solar cells. It has been first described by Swanson et al. on Sunpower IBC modules [11]. In 2018, Yamaguchi et al. demonstrated on n-type PERT cell technology [12] that a degradation of PID-p type saturates after 60 s. This has been explained by the presence of K ...

Bifacial passivated emitter and rear cell (PERC) solar cells are promising candidates to reduce levelized cost of electricity since a rear-side power gain can be achieved with minor changes in cell production. However, in addition to the potential-induced degradation of the shunting type (PID-s), some bifacial solar cells may exhibit another degradation related …
Bifacial passivated emitter and rear cells (PERC+) can suffer from potential‐induced degradation (PID) of the rear side. Rear‐side PID tests of industrial solar cells lead to more than 12% power degradation that is not recoverable under illumination or dark storage. A microstructural root‐cause analysis of the rear side reveals localized spots with …
PID in p-type solar cells is triggered by sodium (Na) that diffuses into stacking faults of the silicon lattice, causing shunt paths through the pn-junction. In addition, it is hypothesised that for bifacial p-PERC solar cells positive charges, such as Na +, accumulate in/on the negatively charged AlO x rear passivation layer due to the potential difference …

A bifacial solar cell (BSC) is any photovoltaic solar cell that can produce electrical energy when illuminated on either of its surfaces, front or rear. In contrast, monofacial solar cells produce electrical energy only when photons impinge on their front side. Bifacial solar cells can make use of albedo radiation, which is useful for applications where a lot of light is reflected on …

Recent research has shown that bifacial PV modules with a glass/glass packaging are prone to different PID mechanisms occurring simultaneously on the front and the rear side of the solar cell.

As indicated in Figure 11, bifacial modules show two types of PID: the shunting type (PID-s) and the polarization type (PID-p). The former affects the shunt resistance by shunting the p-n junction due to ion migration into stacking faults, while the latter corresponds to a loss of surface passivation due to ion accumulation on the passivation layer [ 29, 30 ].
This work presents a comparison between the PID mechanisms of p-type and n-type c-Si solar cells. The reasons for PID effect by p-type cells is the local shunting, …
