The perovskite structure consists of a cubic arrangement of BX 6 octahedra that share corners, with the A cations located within the cavities formed by the octahedra [1, 2], and can be classified into various categories, as shown in Fig. 1 (i).
The binary two-dimensional strategy takes effects not only at the interface but also in the bulk, which enables efficient charge transport in a wide-bandgap perovskite solar cell with a stabilized efficiency of 20.79% (1 cm 2).
The ordered and stable binary metal perovskite can be achieved by moderate zinc (Zn) substitution of Pb, which is via an appropriate lattice constriction within BX 6 octahedra to relax the lattice strain. An appreciated PCE of 20.1% can be achieved by using the restriction CH 3 NH 3 (1Zn:100Pb)I 3-x Cl x and excellent stability.
The extracted electrons and lithium ions recombine at the interface between the perovskite solar cell and the lithium-ion battery, completing the charge transfer process.
The number of layers and perovskite layering in 2D-based perovskites, especially quasi-2D perovskites, play a vital role in determining the electrochemical performance of energy storage systems [52, 115], as shown in Fig. 9, reported a 2D perovskite with a crystal structure of (BA) 2 (MA) 3 Pb 4 Br 13, featuring an interplanar distance of 20.7 Å.
Photo-charged battery devices are an attractive technology but suffer from low photo-electric storage conversion efficiency and poor cycling stability. Here, the authors demonstrate the use of perovskite solar cells in conjunction with a lithium ion battery which displays excellent properties.
