Photovoltaic Squeegee Manufacturing

How efficient is a solar squeegee?

Concurrently, the efficiency, a holistic measure of a cell's ability to convert incident solar energy into electrical energy, suggests that a squeegee speed of 170 mm/s fosters an optimal interaction between the incident light and the cell's active materials.

Does a 170 mm squeegee speed improve solar cell performance?

Through a combination of experimental and analytical methodologies, we identified that a 170 mm/s squeegee speed significantly boosts solar cell performance. This optimization improved electrical and optical performance, achieving a J sc of 38.96 mA/cm 2, a V oc of 684.29 mV, an FF of 78.77 %, and a PCE of 21.00 %.

Do squeegee speeds affect the metallization process of N-Topcon solar cells?

Our investigation delves into optimizing the metallization process of n-TOPCon solar cells, focusing on the effect of different squeegee speeds 170 mm/s, 100 mm/s, and 30 mm/s on the quality of metallization [10, 11].

What is squeegee speed?

Results and discussion In photovoltaic technology, the squeegee speed during the screen-printing process of solar cell metallization stands as a critical parameter. It denotes the rate at which the squeegee moves to spread the conductive paste over the wafer through a patterned mask .

Does squeegee material affect print performance?

versus metal squeegees to understand the impact of squeegee material on print performance. Because polymer squeegees have elasticity, part of the squeegee will extend into the stencil aperture during stencil printing, resulting in a “scooping” effect, which produces a trough-like finger shape (Fig. 3). Figure 6.

Does squeegee speed affect electrical interconnectivity?

Notably, the metal fingers' physical uniformity was improved at the lowest assessed squeegee speed. This observation points to a more consistent metal deposition process, which can significantly affect the electrical interconnectivity within the cell's circuitry [, , , ].
