| 제목 | Enhanced performance and stability in quantum dot solar cells with metal nanoparticle buffer layer. |
| 초록 | Near-infrared PbS quantum dots (QDs) have emerged as promising candidates for photovoltaic applications because of a tunable energy band-gap that covers the optimal band-gap range for single and multijunction solar cells. However, fabrication of these recent QD devices requires high-temperature annealing (＞500 oC) of the TiO2 buffer layer or two different processing atmospheres, including an inert gas environment. In this study, we demonstrate metal nanoparticle / PbS solar cells in which the PbS QD and metal nanocrystals are both solution-processed in air and at room temperature. By controlling the crystalline size of the nanoparticles and the thickness of buffer layers, the efficiency of device was enhanced. Furthermore, the performance of devices remains unchanged for over 30 days. |
