Why is laser dicing used in the PV industry?

In the case of product power, the laser dicing technology has already been used in the PV industry because this technology shows approximately 3 ∼ 5% power gain by half-cell cutting.

How to passivate laser separated PERC solar cells?

The current work introduces two different approaches for passivating the laser separated PERC solar cells. The experiments were performed on p-type PERC monofacial cells and laser scribe and mechanical cleavage (LSMC) technique was used to obtain sub-cells from the host cells.

How does laser cut edge affect PERC solar cell recombination?

The laser cut edge causes a high recombination of the charge carriers, which negatively affects the pseudo fill factor as well as open-circuit voltage of the cell. The current work introduces two different approaches for passivating the laser separated PERC solar cells.

What are micro-concentrator photovoltaics modules?

Micro-Concentrator photovoltaics modules promise to overcome the limitations of CPV such as thermal losses or resistive losses. Miniaturization involves new challenges in the field of cells fabrication, particularly the management of perimeter recombinations.

How are solar cells cut?

Cells were cut by laser scribing and mechanical cleaving (LSMC) technology ( Han et al., 2022 ). The module structure is the same as the conventional product in the PV industry. The module comprises the half-cut 144 cells and six strings with 0.26 mm-diameter wire.

What is the use of III–V materials in photovoltaic field?

The use of III–V materials enables to obtain semi-conductors with tunable bandgaps. This property can be used in the photovoltaic field to target different spectral ranges. III–V materials can absorb wavelengths ranging from mid-infrared to ultraviolet region.
