6 FAQs about [The impact of black edges on photovoltaic module cells]

Does edge quality affect photovoltaic characteristics?

The edge quality of such junction does greatly affect the photovoltaic characteristics, especially in the IBC-DFHJ structure, where the edge region of the heterojunction is longer than that of conventional one due to the interdigital structure of HTL and ETL.

Can photovoltaic modules detect black core faults?

The proposed model demonstrates its ability to detect “black core”, “crack”, and “edge” faults with global accuracies of 0.93, 0.868, and 0.95, respectively. Furthermore, the proposed model estimates the power output of photovoltaic modules with a normalized mean absolute error of 0.03547 and a normalized root mean squared error of 0.04892.

How does edge recombination affect the efficiency of solar cells?

Because of the influence of edge recombination, the efficiency of silicon solar cells with a small area is often lower than that with a large area (a larger average distance from the edge region). In the IBC solar cells, the edge region of p-n junction is even longer in the interdigital structure of positive and negative electrodes.

Can a defect affect the power output of a PV module?

As presented in Section 3.2.2, in the equivalent circuit representation of the PV module, every two rows are in series and independent of the other rows due to by-pass diodes (Fig. 10). Therefore, while estimating the power output of the PV module, any defect in the grouped 20 PV cells will not affect the power output of the remaining PV cells.

Why do hard-mask solar cells have a poor fill factor?

Without the interfacial passivation layer, the solar cells fabricated by the hard-mask method suffer severe edge recombination with loss of 3 × 10 −4 A and a quite poor fill factor (FF) of ~66%, suggesting that the edge recombination could be another important issue affecting the FF besides the series resistance.

Are PV modules prone to faults?

PV modules play a pivotal role in harnessing solar energy for sustainable power generation. However, they are prone to various defects and faults that impact their performance. As mentioned in , the main reason of occurrence faults in PV modules and cells is degradation over time.
