How efficient are champion perovskite solar cells?

Champion perovskite solar cells demonstrate power conversion efficiencies as high as 19.9%, proving the transferability of established manual spin-coating processes to automatic setups. Comparison with human experts reveals that the performance is already on par, while automated processing yields improved homogeneity across the substrate surface.

Are perovskite solar cells repeatable?

This process is typically difficult to reproduce and transfer and is now enhanced to exceptional repeatability in comparison to manual processing. Champion perovskite solar cells demonstrate power conversion efficiencies as high as 19.9%, proving the transferability of established manual spin-coating processes to automatic setups.

Can spin coated perovskite be applied to large scale coating methods?

One obstacle in directly applying spin coated perovskite formulations to large scale coating methods is the faster drying process of spin coated solutions compared to other conventional industrial coating methods. This is due to the combination of centrifugal force and gas flow generated by the spinning substrate.

What happens when perovskite film is prepared by spin coating?

First, when the perovskite film is prepared by spin coating, the solvent accumulates in the upper part of the layer: the upper layer is richer in solvent than the lower one. On the other hand, Pb of perovskite is concentrated in the layer lower part. This surface solvent excess is eliminated upon the first seconds of annealing.

How are CS containing perovskite films fabricated in two-step sequential spin-coating method?

However, in two-step sequential spin-coating method, Cs containing perovskite films have most commonly been fabricated through dissolving Cs salts into the lead salts precursors, due to the high solubility of Cs salts in the commonly used DMF and/or DMSO solvent.

How can perovskite-based optoelectronics be used in a commercial spin-coating robot?
