“…Although the best BHJ solar cells based on SM24 show a PCE of 6.42% that is lower than that of porphyrin monomer and DPP molecules, there still remain many molecular engineering possibilities for further improvement including attaching different electron acceptors or varying the linkers between two porphyrin units.

In recent times, fused aromatic DiketoPyrroloPyrrole-(DPP)-based functional semiconductors have attracted considerable attention in the developing field of organic electronics. Over the past few years, DPP-based semiconductors have demonstrated remarkable improvements in the performance of both organic field-effect transistor (OFET) and organic photovoltaic (OPV) devices due to the favourable features of the DPP unit, such as excellent planarity and better electron-withdrawing ability. Driven by this success, DPPbased materials are now being exploited in various other electronic devices including complementary circuits, memory devices, chemical sensors, photodetectors, perovskite solar cells, organic light-emitting diodes, and more. Recent developments in the use of DPP-based materials for a wide range of electronic devices are summarized, focusing on OFET, OPV, and newly developed devices with a discussion of device performance in terms of molecular engineering. Useful guidance for the design of future DPP-based materials and the exploration of more advanced applications is provided.

With developments in materials, thin-film processing, fine-tuning of morphology, and optimization of device fabrication, the performance of organic solar cells (OSCs) has improved markedly in recent years. Designing low-bandgap materials has been a focus in order to maximize solar energy conversion. However, there are only a few successful low-bandgap donor materials developed with nearinfrared (NIR) absorption that are well-matched to the existing efficient acceptors. Porphyrin has shown great potential as a useful building block for constructing low-

“…More recently, Cao et al reported new porphyrin‐DPP conjugates (Figure ) . (DPP‐ZnP‐E)2, (DPP‐ZnP‐E)2‐2T, and (DPP‐ZnP‐E)2‐Ph have the same backbone except for the central conjugated bridge, which are diethynylene, diethynylene–dithiophene, and diethynylene–phenylene units.…”

International audienceAdvances in the synthesis and application of highly efficient polymers and small molecules over the last two decades have enabled the rapid advancement in the development of organic solar cells and photovoltaic technology as a promising alternative to conventional solar cells, based on silicon and other inorganic semiconducting materials. Among the different types of organic semiconducting materials, porphyrins and BODIPY-based small molecules and conjugated polymers attract high interest as efficient semiconducting organic materials for dye sensitized solar cells and bulk heterojunction organic solar cells. The highest power conversion efficiency exceeding 9% has been reported so far for porphyrin small molecules and 8.60% for conjugated polymers based on porphyrins. On the other hand, small molecules and conjugated polymers based on BODIPY moiety have been successfully used as donor materials for solution processed bulk heterojunction organic solar cells, and the resultant devices showed power conversion efficiencies exceeding 5.5%. In this article, the development of molecular design of porphyrins and BODIPY small molecules and polymers for bulk heterojunction organic solar cells are reviewed, and a guideline for the structure-performance relationship is provided
