Does laser cutting damage solar cells?
Most of the existing reports on solar cell cutting are focused on the laser wavelength, type, performance, and cutting parameters (depth of cut, speed, and direction of cut) to illustrate how to reduce the damage (hidden cracks, p-n junction leakage, and contamination) caused by laser cutting on solar cells [ 16, 17 ].
Can a laser cut a bifacial solar cell?
The optimized laser cutting conditions using a Q-switched, nanosecond Nd:YAG fiber laser were identified as a double cutting process on the rear side of bifacial solar cell. The optimal cutting parameters is achieved under a laser cutting power of 5 W, the laser repetitive frequency of 30 kHz, and the scribing speed of 120 mm/s.
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.
Do laser cutting conditions affect the power output of half-cell bifacial silicon photovoltaic (PV) modules?
The development of half-cell PV modules requires an in-depth analysis of the laser cutting and mechanical breaking induced losses. Herein, we have studied the influence of laser cutting conditions on the power output of half-cell bifacial silicon photovoltaic (PV) modules.
How are bifacial solar cells cut?
The bifacial solar cells were cut by using a Q-switched, nanosecond, Nd: YAG fiber laser scribing machine. The operating parameters of the laser machine are listed in Table 2. The optimal scribing speed was found to be 120 mm/s, which is 80% of the maximum cutting speed [ 23 ].
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.
