dc.description.abstract | Perovskite solar cells have been drawing attention because of their excellent performance exceeding the efficiency of first-generation crystalline silicon solar cells, light weight and low cost. With the excellent photovoltaic properties including the high absorption coefficient and high carrier mobilities in perovskite, performance of perovskite solar cells has significantly increased from 3.8% to 25.5% within about 10 years. Unfortunately, the performance has almost reached to the Shockley-Queisser limit which the theoretically calculated through the bandgap of the photo-active layer. For exceeding the Shockley-Queisser limit, additional photon absorption should be needed in perovskite solar cells. In this study, we proposed the perovskite/organic hybrid structure having complementary absorption. These perovskite/organic hybrid solar cells allows to extend the absorption from visible to near-infrared by introducing the organic materials having the infrared absorption spectra. In this dissertation, first of all, it deals with the research on improving the crystallinity of perovskite to improve the efficiency of the perovskite solar cell itself. Then, it will introduce the hybrid energy band structure and the calculation of the expected efficiency gain through optical simulation, and the analysis of experimental values, etc. | - |
