A Development of Highly Efficient Perovskite Solar Cells under Indoor Light Condition through Modified Precursor Solution by Surfactant Insertion |
| 초록 |
Perovskite solar cells (PSCs) have a unique set of intriguing optoelectronics such as superior light absorption coefficient, high carrier mobility, and long carrier diffusion length. Although PSCs have shown a tremendous power conversion efficiency during the last decades, the interface or bulk defects at the perovskite layer are fatal to achieving highly efficient PSCs under indoor light conditions. To boost performance, this work introduced a surfactant, quaternary ammonium halides (QAHs), into a perovskite precursor solution to passivate the defects. The Zeta Potential, Scanning Electron Microscope, Grazing-Incidence Wide-Angle X-ray Scattering, steady-state and time-resolved photoluminescence measurements revealed that the QAHs insertion into the precursor solution passivate the interface defects and improved perovskite grain quality. Finally, the perovskite solar cells show over 30% power conversion efficiency under indoor light conditions (1000 Lx). |
