6 FAQs about [Solar alkali polishing automation equipment debugging]

Does acid polishing improve the FF of solar cells?

This can improve the contact characteristics without significantly affecting the passivation characteristics, enabling solar cells to achieve higher FF (83.30%) and average efficiency (24.15%). Compared with the acid polishing sample, the efficiency of the micro-alkali texturing sample is increased by 0.12%.

Does micro-alkali polishing affect the efficiency of Topcon solar cells?

The micro-alkali polishing after acid polishing still caused poor contact, and the fill factor decreased slightly, resulting in a 0.06% drop in efficiency. This has been described in detail in the previous chapters. Table 3. I-V parameters of TOPCon solar cells with different surface morphologies and different oxidation time.

Can alkali texturing be used on the backside of solar cells?

Alkali texturing is usually used on the front of solar cells to form a pyramid structure to reduce reflectivity and increase light absorption. The use of alkali texturing on the backside requires consideration of the effect of the presence of pyramids on the surface which may result in a significant increase in surface dangling bonds and defects.

Can wet chemical polishing be used for industrial N-Topcon solar cells?

Wet chemical polishing for industrial type PERC solar cells Influence of rear surface pyramid base microstructure on industrial n-TOPCon solar cell performances Large-area bifacial n-TOPCon solar cells with in situ phosphorus-doped LPCVD poly-Si passivating contacts Sol. Energy Mater. Sol. Cell. ( 2022), p. 236

Does micro-alkali polishing cause ohmic contact deterioration?

Even short-time micro-alkali polishing of acid-polishing surface can still cause deterioration of the ohmic contact. By changing the thermal oxidation growth time of the tunnel oxide layer, the effect of the tunnel oxide layer on the characteristics of TOPCon solar cells with different surface morphologies was studied.

Why are micro-alkali polishing samples different from acid-polishing samples?

Due to the short micro-alkali texturing time, local polishing and local texturing coexist, and the height of the tiny pyramids grown is small, so the surface flatness and passivation characteristics are less different than those of acid-polishing samples.
