6 FAQs about [Perovskite battery carbon counter electrode slurry]

What are carbon counter electrode materials for perovskite solar cells and modules?

Why is a perovskite deposited before a carbon electrode?

This structure is referred to as low-temperature due to the processing temperatures of the carbon electrode, which are low enough (≤120 °C) to avoid the decomposition of the perovskite absorber. Therefore, the perovskite can be deposited before the carbon electrode, eliminating the need to infiltrate the precursor solution through the carbon.

Can a perovskite charge transfer to a carbon electrode?

The feasibility of the charge exchange between the perovskite and the carbon electrode was examined through electrochemical impedance spectroscopy, where the low charge transfer resistance in the high-frequency region was reported to demonstrate a favourable charge transfer to the low-temperature carbon electrode. [ 108]

Why should a carbon electrode be aligned with a perovskite layer?

Moreover, the band alignment of the carbon electrode with the perovskite layer must be engineered to create an ohmic contact for efficient hole (electron) extraction and prevent electron (hole) backscattering in an n– i –p (p– i –n) architecture.

How can we overcome the losses at the perovskite–carbon interface?

As we discussed in the previous sections, the most straightforward approach found in the literature to overcome the losses at the perovskite–carbon interface involves introducing an alternative HSL that is compatible with the solvents employed in the carbon paste.

Why do perovskite solar cells have low power conversion efficiency?

However, perovskite solar cells with carbon electrodes usually have relatively low power conversion efficiency, which can be related to the recombination process and charge transfer process at the interfaces of carbon electrodes. For the carbon electrodes printed at low temp., CuSCN hole conductors can decrease the recombination process of devices.
