“…Benefitting from these, TiO 2 NaPAs CsPbI 2 Br PSCs exhibited a higher PCE of 11.35% (a J SC of 15.18 mA cm À2 , a V OC of 1.10 V, and a FF of 0.688) and superior long term stability compared to that of the TiO 2 planar CsPbI 2 Br PSCs. 78 Meanwhile, quantum dots have also been utilized to modify the ETL/CsPbI 2 Br interface for CsPbI 2 Br PSC application. 79,80 It was found that borophene quantum dot (BQD) interfacial layer not only improved the contact between TiO 2 and CsPbI 2 Br to reduce interfacial recombination, but also induced a well-matched energy alignment for effective charge transport.…”

Perovskite solar cells (PSCs) are being rapidly developed at a fiery stage due to their marvelous and fast-growing power conversion efficiency (PCE). Advantages such as high PCE, solution processability, tunable band gaps, and flexibility make PSCs one of the research hot spots in the energy field. Flexible PSCs (f-PSCs) owing to high power-to-weight ratios can be promising candidates to serve as power sources in mobile energy systems, space energy systems, portable functional devices, and so on. Herein, we give a review on recent progress in f-PSCs involving flexible substrates and flexible transparent electrodes, performance enhancement by optimizing functional layers, large-scale fabrication techniques, flexibility promotion strategies, and their potential applications. Furthermore, perspectives are discussed on the future development of f-PSCs.

The Serious interfacial recombination and low-efficient hole extraction at the interface of the carbon electrode and perovskite film have strikingly limited the performance improvement of carbon-based inorganic perovskite solar cells (PSCs). Here, hydrophobic poly(3-hexylthiophene) (P3HT) and polystyrene (PS) are employed as the interlayer to modify the interface of the CsPbIBr2 perovskite and the carbon electrode for enhancing the hole extraction and reducing the interfacial recombination. The effect of the PS and P3HT interlayer on the stability of the CsPbIBr2 perovskite film and the performance of carbon-based devices are systemically investigated. Both PS and the P3HT interlayer remarkably enhance the stability of the CsPbIBr2 perovskite film by inhibiting the intrusion of ambient moisture. However, the incorporation of the PS interlayer deteriorates the efficiency of the device, mainly owing to the low tunneling rate of the holes within the insulated PS layer. By contrast, introduction of the P3HT interlayer greatly improves the performance of the carbon-based CsPbIBr2 cells. The cell with the P3HT interlayer delivers a high power conversion efficiency of 7.47%, largely increased by 36% compared with the efficiency for the control device. Additionally, the P3HT interlayer greatly promotes the long-term stability of carbon-based CsPbIBr2 PSCs in ambient conditions.
