Recently, Liu Shengzhong, a researcher of the thin-film silicon solar cell research group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Yang Dong, a researcher at Shaanxi Normal University, were invited to publish a review article on "Angew. Chem. Int. Ed." And explored the latest advances in flexible perovskite solar cells, application costs, and potential opportunities and challenges.
With the rapid development of technology, there is an increasing demand for flexible electronic devices such as portable electronic devices, electronic displays, and wearable electronic products. Flexible solar cells have become the future portable electronic products due to their light weight, easy transportation, and installation. One of the best choices for products. The new perovskite solar cells developed in recent years have the advantages of simple structure, low temperature processing, high efficiency, and low price, which are very suitable for the preparation of flexible solar cells. Accelerated the research of flexible solar cells based on perovskite materials. The research focuses on how to improve the efficiency of flexible perovskite solar cells, increase the effective area, reduce costs, achieve low temperature preparation, and large-scale production. The team has made a series of advances in the field of perovskite solar cells in recent years, creating the highest efficiency of flexible and rigid planar perovskite solar cells, and is still the most efficient of flexible and rigid planar perovskite solar cells.

This review describes the various preparation methods of low temperature perovskite films and their respective advantages and disadvantages. The application of low temperature interface layers (including electron and hole transport layers) in flexible perovskite solar cells is described. The important process of different flexible electrodes in the development of flexible perovskite solar cells; the environmental and mechanical stability of flexible perovskite solar cells, and how to improve their environmental stability using flexible packaging technology. Subsequently, the article looks forward to The application of flexible perovskite solar cells in portable electronic devices such as wearables, and estimates the cost of large-scale vacuum roll-to-roll preparation for flexible perovskite solar cells. Finally, the review predicts and emphasizes flexible perovskites. Opportunities and challenges faced by solar cells in actual production in the future.
