英文摘要： Facing the demand for novel low-cost clean energy and focusing on the scientific problems associated with perovskite solar cells, it is worth exploring a new method under the low cost condition to improve the photovoltaic performance of perovskite solar cells based on the design and preparation of materials and the development of the new material system with independent intellectual property rights. In this proposal we should study intensively a hole-conductor free fully-printable perovskite solar cells, which the nanocrystalline layer, the space layer and the carbon counter electrode layer are screen-printed layer by layer on a single conducting substrate, and then perovskite material is filled into the porous layers. We should optimize the perovskite materials AMX3 on structure by introducing amphipathic molecules to form mixed cation perovskite materials. Meanwhile, we should develop the environmental-friendly stable perovskite materials with wider absorption spectra and higher efficiency by a variety of methods such as multiple halogens blending method. Moreover, the energy band of nano metal oxide materials should be adjusted and controlled, the work function of the mesoscopic carbon counter electrodes should be improved. Assisted with these optimization we hope to find a way to increase the efficiencies of the light harvesting, charge transfer, charge transport and charge separation within the hole-conductor free fully-printable perovskite solar cells and find out the relationship between material structure and device performance. After that a low-cost solar cell with high efficiency exceeding 18% should be obtained. This project should provide material system with independent intellectual property rights and the theoretical and technical support.
