Preparation of flexible perovskite batteries

Can flexible perovskite solar cells be used in portable electronics?

Flexible perovskite solar cells have attracted widespread research effort because of their potential in portable electronics. The efficiency has exceeded 18 % owing to the high-quality perovskite film achieved by various low-temperature fabrication methods and matching of the interface and electrode materials.

What are flexible perovskite solar cells (fpscs)?

Flexible perovskite solar cells (FPSCs) are supposed to play an important role in the commercialization of perovskite solar cells due to their unique properties, such as high efficiency, thin thickness and being compatible with roll to roll (R2R) process for mass production.

How to prepare a perovskite film?

Kim et al. employed a hot slot-die coating method to prepare perovskite films by heating the substrate to 130 °C during the deposition process [ 89]. Poly (ethylene oxide) PEO was introduced into perovskite films to significantly improve the stability. The flexible devices exhibited a best PCE of 11.7%.

Are perovskite solar cells a viable alternative to conventional energy harvesting?

The integration of perovskite solar cells into diverse applications, beyond conventional energy harvesting, signifies the expanding role of these materials in various technological domains. In summary, the reviewed literature showcases the diverse and evolving landscape of perovskite solar cell research.

How to make a perovskite precursor solution?

In this process, a one-step perovskite precursor solution was made by adding both PbI 2 and MAI in the DMF+DMSO solution with a volume ration of 1:4. The precursor solution was made at one-step, it was directly spin-coated above the substrate at an rpm of 3000 for 50 s.

How can a large-scale perovskite device be manufactured?

For larger-scale perovskite device fabrication, the key point is to remain the quality of the perovskite film such as uniform and coverage. Hopefully, the combination of vacuum deposition methods and the low-temperature techniques offers a promising way to realize the mass production of the flexible PSCs.
