Silver pastes for solar cell metallization consist of silver particles, which finally provide the conductivity of the printed and sintered structures, as well as glass frits opening the passivation layer during sintering [ 25 ].
By simulating the electrical properties of solar cells, we can visualize the excellent electrical properties of capillary suspension silver paste. These results are closely related to the laser power of the PTP technology. Lower transfer power and higher η provide new avenues to enhance solar cell efficiency and cut down on expenses. 4. Conclusion
Photovoltaic silver paste is applied to the surface of silicon solar cells through screen-printing, after which the paste is dried and sintered to form a grid electrode. Fig.1. Architecture of TOPCon solar cell on n-type monocrystalline silicon wafer.
4. Conclusion The preparation of the front silver paste used for c-Si solar cells can be achieved through the use of capillary suspension, which can then be applied through screen-printing and PTP technology.
It has been found that the low viscosity silver paste has a stronger ability to flow, resulting in irregular flow after contact with the silicon cell wafers. This can lead to a deterioration in the morphology and uniformity of the silver finger line , . The printing results of the A7 sample are also representative.
Paste transfer, or laydown, is a characteristic feature of a printing process not only for metallization of solar cells. Results for pastes M1–M3 obtained with the above-mentioned layout screen at different printing speeds for a 50 µm finger opening are summarized in Table 2.
