Triple Halide-Bridged Perovskites for Highly Efficient Solution-Processed Hybrid Solar Cells |
| 초록 |
Hybrid organic-inorganic perovskite materials have attracted substantial attention as photovoltaic light abosorbers due to their outstanding physical properties and outstanding power conversion efficiencies (PCE). Structural variation of perovskite absorbing materials has proven to be an effective route to improve device performance; notably tuning of the halide anion composition constitutes a key approach to control material properties. In this work, we demonstrate a bridged ternary halide approach to process materials with the formula MAPbI3-y-xBryClx which yields high PCEs in planar, p-i-n type heterojunction perovskite solar cells. This ternary halide perovskite system improves device performance from 12% to 16% when an optimal concentration of 10% Br is incorporated into the binary Cl – I systems, via increases in short-circuit current density, open-circuit voltage and fill factor which arise from the formation of homogeneous crystal domains and widening of the optical band gap. |
