中文摘要:
      无掺杂空穴传输材料是实现钙钛矿太阳能电池(PSCs)实用化的关键问题。本论文合成了具有高的热稳定性、对可见光谱全吸收性质的黑卟啉分子,5,10,15,20-四[3,5-二(叔丁基)苯基]-β,β'-四萘醌[6,7-g]锌卟啉(T1),研究了光物理、电化学性能和成膜性。T1最高占据分子轨道(HOMO)能级与spiro-OMeTAD相近,能够很好地与钙钛矿材料MAPbI3相匹配。制备了以T1分子为空穴传输层的PSCs,器件的能量转换效率(PCE)达到13.43%,优于相同条件下的基于spiro-OMeTAD的器件(11.63%)。
英文摘要:
      The dopant-free hole-transporting materials are a key issue to realize the practical application of perovskite solar cells (PSCs). In this work, a black porphyrin molecule with high thermal stability and complete visible light absorption, 5,10,15,20-tetra[3,5-di(tert-butyl)phenyl]- β,β'-tetranaphthoquinone[6,7-g] zinc porphyrin (T1), was synthesized successfully and the studies of its photo physics, electrochemical properties and film-forming properties were carried out. Moreover, the highest occupied molecular orbital(HOMO) energy level of T1 is similar to that of spiro-OMeTAD, which can be well matched with the perovskite material MAPbI3. The power conversion efficiency (PCE) of the device based on T1 without any dopant can reach 13.43%, which was much higher than that of spiro-OMeTAD-based devices (11.63%) prepared under the same conditions.
