“…In OPV devices, divalent Sn(II)Pcs have found applications as donors due to their narrow bandgap and p-type conductivity. − However, there are only a few reports investigating n-type tetravalent Sn(IV)Pcs in OPVs. Two axially substituted SnPcs ((OR) 2 -SnPcs) have been employed as ternary additives in poly(3-hexylthiophene) (P3HT) and phenyl-C 61 -butyric acid methyl ester (PC 61 BM) OPVs .…”

Tin(IV) phthalocyanines (SnPcs) are promising candidates for low-cost organic electronic devices, and have been employed in organic photovoltaics (OPVs) and organic thin-film transistors (OTFTs). However, they remain relatively understudied compared to their silicon phthalocyanine (SiPc) analogues. Previously, we reported the first solution-processed SnPc semiconductors for OTFTs and OPVs; however, the performances of these derivatives were unexpected. Herein to further study the behavior of these derivatives in OPVs and OTFTs, we report the synthesis along with optical and thermal characterization of seven axially substituted (OR)2-SnPcs, five of which were synthesized for the first time. Density functional theory (DFT) was used to predict charge-carrier mobilities for our materials in their crystal state. The application of these SnPcs as ternary additives in poly(3-hexylthiophene) (P3HT)/phenyl-C61-butyric acid methyl ester (PC61BM) OPVs and as semiconductors in solution-processed n-type OTFTs was also investigated. When employed as ternary additives in OPVs, all (OR)2-SnPcs decreased the power conversion efficiency, open-circuit voltage, short-circuit current, and fill factor. However, in OTFTs, four of the seven materials exhibited greater electron field-effect mobility with similar threshold voltages compared to their previously studied SiPc analogues. Among these SnPcs, bis(triisobutylsilyl oxide) SnPc displayed the greatest electron field-effect mobility of 0.014 cm2 V–1 s–1, with a threshold voltage of 31.4 V when incorporated into OTFTs. This difference in electrical performance between OTFT and OPV devices was attributed to the low photostability of SnPcs.

“…Owing to the plasmonic light scattering, the NPs with a high scattering cross-section can reduce the reflective losses and provide an enhanced effective path length to increase light incoupling efficiency [133][134][135][136]. Plasmonic scattering efficiency can be tailored by the shape, environment, distribution and size of NPs.…”

Lightweight and low-cost organic photovoltaics (OPVs) hold great promise as renewable energy sources. The most critical challenge in developing high-performance OPVs is the incomplete photon absorption due to the low diffusion length of the carrier in organic semiconductors. To date, various attempts have been carried out to improve light absorption in thin photoactive layer based on optical engineering strategies. Nanostructureinduced light harvesting in OPVs offers an attractive solution to realize high-performance OPVs, via the effects of antireflection, plasmonic scattering, surface plasmon polarization, localized surface plasmon resonance and optical cavity. In this review article, we summarize recent advances in nanostructure-induced light harvesting in OPVs and discuss various light-trapping strategies by incorporating nanostructures in OPVs and the fabrication processing of the micro-patterns with high resolution, large area, high yield and low cost.
