Interfacial Layer Control of Perovskite Solar Cells to Achieve High Efficiency in Low-Light Environments |
| 초록 |
Recently, the demand for indoor Internet of Things (IoT) sensors that can be driven with low power has increased exponentially. Therefore, a self-powered system should be developed at indoor light environment employing a photovoltaic device. The excellent electrical properties of the perovskite material reveal the possibility of effectively absorbing and photoelectrically converting light in the indoor lighting to show excellent efficiency. In this presentation, We modified the interfacial electron transport layer (ETL) based on n-i-p perovskite solar cells (PSCs) for indoor lighting applications. We investigated trap density through Space charge limited electron (SCLC) measurements and changes in recombination such as electrochemical impedance spectroscopy(EIS) and time resolved photoluminescence(TRPL). We suggest a promising approach to design devices suitable for high photoelectric conversion efficiency in low-light environments by introducing interface control material. |
