What types of photovoltaic cells are used in B-Si-based solar cells?

In the literature, there are currently a few types of photovoltaic cell configuration typically used in b-Si-based photovoltaic cells, such as the conventional large-area solar cell, the IBC configuration, the tandem configuration, and the PERL configuration.

What is a black silicon solar cell?

Black silicon is layered on the front surface, usually with another passivation layer. In a recent study by Savin et al. [ 6 ], they have reported a record-breaking b-Si solar cell efficiency of 22.1% using an IBC configuration. Fig. 12 (b) shows the configuration of the solar cell used in their study.

What are gridline defects in solar cells?

Gridline defects also developed at the edge of the long crack, seen as dark horizontal lines in the EL images. These defects correlate to the printed gridlines on the solar cell which are engineered to extract the current generated by the photovoltaic effect and carry it to the nearest interconnect ribbon.

What is the temperature of a photovoltaic cell?

Temperatures of photovoltaic cells are typically assumed to be at 300K. In real condition, the temperature of the photovoltaic cell fluctuates due to the generation, transport and recombination/scattering of electrons and phonons in the cell [ 181 ].

What are the applications of black silicon in photovoltaics?

Applications and assisted properties of black silicon in photovoltaics Some notable properties of b-Si are the superior absorption of visible light, antibacterial properties, and hydrophobicity [ 4, 87, 91 ].

How to identify defects in solar cells?

Other defects with origins in manufacturing and environmental stress can be observed, such as belt marks, dark edges along one or two sides of the cell, corrosion along the ribbon interconnects, and dead cells. Computer vision has proven effective to automatically identify defects in EL images of solar cells.
