| 英文摘要 | Polymer solar cell (PSC) with bulk heterojunction structure has attracted considerable attention due to its potential for harnessing low-cost solar energy and making flexible devices. The design and application of highly efficient conjugated polymers has enabled the rapid progress in the development of organic photovoltaic technology, and the power conversion efficiency (PCE) has been boosted to over 11%. A highly efficient polymer donor should possess several intrinsic features, such as a broad absorption spectrum with high extinction coefficient, suitable molecular energy level alignment of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) levels to afford a sufficient driving force for efficient charge separation with minimum energy loss, high charge mobilities to facilitate charge transport and favorable blend morphology to facilitate exciton diffusion and charge separation. From early homopolymer polythiophene system to typical donor-acceptor (D-A) structure polymers, many conjugated polymer donors have been developed and applied in fabricating PSC device. In this review, we first summarize some of our works from the polythiophene with the two conjugated side chains to benzodithiophene (BDT) based D-A polymers. Since the blend morphology plays a vital role in determining the performance of the PSC device, we also did some works about the morphology optimization from the aspect of molecular design. Recently, fullerenefree PSC has emerged as a new horizon in the field of PSC, and we have demonstrated fullerene-free PSC device with PCE over 11% by using BDT-based polymer. In addition, we also summarize some other works about the fullerene-free PSC in our group. In the end, after a brief summary, we present some inevitable questions about the development of commercial PSC, such as the efficiency, stability, manufacturability and reproducibility. From the materials and processing methods, we think these problems can be solved and except that PSC has real applications in the near future. |
