“…The optimized OPVs based on this small molecule exhibited a photoelectron response up to 1000 nm with a PCE of 8.45% (Figure ). Hadmojo et al adopted PDI as the acceptor unit to link with a zinc porphyrin core through ethyne bridges, and the synthesized molecule PDI‐P Zn ‐PDI exhibits a low bandgap of 1.27 eV owing to the large conjugated system with strong ICT effect . The fabricated OPVs based on PTB7‐Th:PDI‐P Zn ‐PDI exhibited a PCE of 5.25% with a low energy loss of 0.54 eV.…”

The inherent advantages of organic optoelectronic materials endow lightharvesting systems, including organic photovoltaics (OPVs) and organic photodiodes (OPDs), with multiple advantages, such as low-cost manufacturing, light weight, flexibility, and applicability to large-area fabrication, make them promising competitors with their inorganic counterparts. Among them, nearinfrared (NIR) organic optoelectronic materials occupy a special position and have become the subject of extensive research in both academia and industry.The introduction of NIR materials into OPVs extends the absorption spectrum range, thereby enhancing the photon-harvesting ability of the devices, due to which they have been widely used for the construction of semitransparent solar cells with single-junction or tandem architectures. NIR photodiodes have tremendous potential in industrial, military, and scientific applications, such as remote control of smart electronic devices, chemical/biological sensing, environmental monitoring, optical communication, and so forth. These practical and potential applications have stimulated the development of NIR photoelectric materials, which in turn has given impetus to innovation in light-harvesting systems. In this review, we summarize the common molecular design strategies of NIR photoelectric materials and enumerate their applications in OPVs and OPDs.

“…The optical bandgap (

) of P Zn -TNI was 1.63 eV, which was calculated from the absorption onset wavelength of 761 nm in the film. We previously reported the pyridine additive effect on the molecular ordering of porphyrin derivatives; pyridine enhances the intermolecular ordering of porphyrin derivatives via coordination to the zinc (Hadmojo et al, 2017 ). As shown in Figure 1B , the absorption of P Zn -TNI was significantly broadened and red-shifted compared to that without pyridine treatment, resulting in the bathochromic shift of 42 nm in the Soret band and 15 nm in the Q-band.…”

“…In addition, the long-wavelength absorption of the Q-band intensifies the light harvesting in the low bandgap area where abundant solar flux exists. However, most of the developed artificial porphyrin derivatives are p-type materials and only a few porphyrin derivatives currently show n-type characteristics with a promising PCEs over 5% (Hadmojo et al, 2017 ; Zhang et al, 2017 ). Exploring new structures for n-type porphyrin materials is challenging in fullerene-free OSCs.…”

The development of n-type porphyrin acceptors is challenging in organic solar cells. In this work, we synthesized a novel n-type porphyrin acceptor, PZn-TNI, via the introduction of the electron withdrawing naphthalene imide (NI) moiety at the meso position of zinc porphyrin (PZn). PZn-TNI has excellent thermal stability and unique bimodal absorption with a strong Soret band (300–600 nm) and weak Q-band (600–800 nm). The weak long-wavelength absorption of PZn-TNI was completely covered by combining the low bandgap polymer donor, PTB7-Th, which realized the well-balanced panchromatic photon-to-current conversion in the range of 300–800 nm. Notably, the one-step reaction of the NI moiety from a commercially available source leads to the cheap and simple n-type porphyrin synthesis. The substitution of four NIs in PZn ring induced sufficient n-type characteristics with proper HOMO and LUMO energy levels for efficient charge transport with PTB7-Th. Fullerene-free organic solar cells based-on PTB7-Th:PZn-TNI were investigated and showed a promising PCE of 5.07% without any additive treatment. To the best of our knowledge, this is the highest PCE in the porphyrin-based acceptors without utilization of the perylene diimide accepting unit.

Artificial light-harvesting n-type porphyrin for panchromatic organic photovoltaic devices

Abstract: We developed a novel NIR-harvesting n-type porphyrin derivative, PDI–PZn–PDI, that shows a low bandgap of 1.27 eV. Panchromatic absorption was extended to the NIR area with a significantly low energy loss of 0.54 eV which led to promising photovoltaic performance.
