6 FAQs about [PMMA in solar cells]

Will PMMA improve the performance of perovskite solar cells?

Moreover, to avoid the direct connection between the spiro-OMeTAD and TiO 2 layer, PMMA is expected to fill surface defects in the perovskite layer, which would contribute to improvements in the photovoltaic performance and stability of perovskite solar cells .

Can PMMA coating film improve the performance of solar cells?

Therefore, it is proved that PMMA coating film can effectively passivate the defects of the pure CsPbI 2 Br films, suppress the charge recombination with increased electron extraction efficiency, which improves the performance of solar cells.

Can PMMA reduce interfacial charge losses in tin-based perovskite solar cells?

Why do PMMA-cspbi 2 BR solar cells perform better?

The decreased defect density in the PMMA-CsPbI 2 Br film is favorable for preventing the charge recombination, which can further improve the V oc and FF of the PMMA-coated CsPbI 2 Br solar cells. This result can also explain the reason for the improved device performance of PMMA-coated CsPbI 2 Br film based solar cells. Fig. 5.

What is the effect of PMMA treatment of PSCs?

Note that the effect of the PMMA treatment of PSCs is similar to the edge isolation in silicon solar cells. One of the last steps in Si cell production consists of the isolation of the cell edges, where the p- and n-doped parts of the device may be in contact, by laser engraving or plasma etching the borders.
