报告摘要：
有机聚合物和钙钛矿杂化物在合成控制，加工及属性调控的进展显著地增强了其太阳能电池性能。聚合物和杂化太阳能电池的性能十分依赖材料吸收光子、激子离解、电荷传输以及在金属/有机/金属氧化物或金属/钙钛矿/金属氧化物界面的效率。在这次讲座中，我们将介绍如何通过有效地整合材料设计以及界面与器件工程以显著提高聚合物和杂化钙钛矿型太阳能电池性能（转换效率>18%）。最后，我们还将介绍一些关于制备串联和半透明太阳能电池的新型器件结构和光学工程策略，以发挥聚合物和钙钛矿太阳能电池的最大潜能。

Abstract:
Advances in controlled synthesis, processing, and tuning of the properties of organic conjugated polymers and perovskites have enabled significantly enhanced performance of organic and hybrid electronic devices. The performance of polymer and hybrid solar cells is strongly dependent on their efficiency in harvesting light, exciton dissociation, charge transport, and charge collection at the metal/organic/metal oxide or the metal/perovskite/metal oxide interfaces. In this talk, the integrated approach of combining material design, interface, and device engineering to significantly improve the performance of polymer and hybrid perovskite photovoltaic cells (PCE of >18%) will be discussed. At the end, several new device architectures and optical engineering strategies to make tandem cells and semitransparent solar cells will be discussed to explore the full promise of polymer and perovskite hybrid solar cells.
