TiO2/RbPbI3 halide perovskite solar cells
چکیده انگلیسی


- We applied the RbPbI3 to a solar cell to determine the performance of 1D perovskite.
- RbPbI3 perovskite shows the superior stability for the environmental conditions.
- The band gap alignment of RbPbI3 perovskite is well matched with that of TiO2.
- The device with RbPbI3 perovskite shows little hysteresis in the J-V scan direction.

Inorganic-organic halide perovskites hold the great promise for next-generation photovoltaics due to their excellent high performance and low cost. However, major limitation for the commercialization of perovskite solar cell can be attributed to the transformation and degradation of lead halide perovskite during the exposure of environmental humidity and photon irradiation. To solve these problems, herein, we apply the one-dimensional and inorganic RbPbI3 perovskite into the solar cell because it shows the superior stability in environmental conditions. After RbPbI3 perovskite was applied into the solar cell with a FTO/TiO2/RbPbI3/Spiro-MeOTAD/Au configuration, the device exhibits an open circuit voltage of 0.62 V, photocurrent density of 3.75 mA/cm2, fill factor of 44.60%, and 1.04% of PCE by reverse sweeping direction. Even though the performance of RbPbI3 device was still lower than other perovskite solar cells, this approach enabled us to establish the key step to make a highly stable perovskite film, leading to the best photovoltaic performance for real applications.

The solar cell was fabricated with one dimensional RbPbI3 perovskite as a light absorber.267
