Abstract

Molecular level one-dimensional (1D) metal halide perovskites possessing large exciton binding energies are generally considered unfavorable for photovoltaic devices. To date, applying 1D perovskites as active materials for solar cells has not been as well explored as 3D and 2D perovskites. Herein, we report a new low-dimensional hybrid perovskite based on 1D 1,4-benzene diammonium lead iodide (BDAPbI 4 ) perovskite. Counterintuitive to the general belief, a high efficiency of up to 14% was achieved for solar cells based on low-dimensional hybrid perovskites containing 1D BDAPbI 4 and 3D MAPbI 3 . More importantly, these solar cells can retain over 95% of their efficiency upon storage for over 1000 h and show impressive stability under continuous illumination and heating.
