“…They found that the device modified by 2-F SAMs showed a highest PCE of 4.4% due to the better energy level matching and passivation of surface traps. 86 Recently, they used a series of phenylboric acid (PBA) SAMs with different terminal groups to modify c-TiO 2 in inverted PSCs. The modified c-TiO 2 shows better hydrophobicity, which made it more compatible with the upper organic active layer and effectively improved the contact with the active layer.…”

Polymer solar cell (PSC) has been developed vastly in the past decade due to the advantages of low cost, lightweight, mechanical flexibility, versatility of chemical design and synthesis, semitransparency, and solution processing. The performance and lifetime of PSCs are highly dependent on the properties of both active materials and their interfaces. The combination of the versatility of organic chemistry and the multitude of well-understood ligand-metal interactions allows self-assembled monolayers (SAMs) of organic molecules to direct control over the electronic and chemical properties at the inorganic-organic interfaces. Thus, SAMs are an attractive pathway to reconcile interfaces with tunable interface properties in PSCs. Hence, this review describes the application of SAMs in PSCs at different interfaces. First, SAMs as alternatives of traditional transporting materials to reduce the barrier at indium tin oxide (ITO)/ active layer interface due to the ability of tuning work function of ITO electrode are discussed. Second, the modifications of metal oxide by SAMs to control the electrical contacts at transporting layer/active layer interface are described. Third, tailoring the properties of the donor/acceptor interface by SAMs to improve the performance of PSCs are summarized. Finally, perspectives and challenges are pointed out for developing highly stable and highperformance PSCs by applying SAMs.

Solution Chemistry to Control Boron-Containing Monolayers on Silicon: Reactions of Boric Acid and 4-Fluorophenylboronic Acid with H- and Cl-terminated Si(100)

The reactions of boric acid and 4-fluorophenylboronic acid with H- and Cl-terminated Si(100) surfaces in solution were investigated. X-ray photoelectron spectroscopy (XPS) studies reveal that both molecules react preferentially with Cl–Si(100) and not with H–Si(100) at identical conditions. On Cl–Si(100), the reactions introduce boron onto the surface, forming a Si–O–B structure. The quantification of boron surface coverage demonstrates that the 4-fluorophenylboronic acid leads to ∼2.8 times higher boron coverage compared to that of boric acid on Cl–Si(100). Consistent with these observations, density functional theory studies show that the reaction of boric acid and 4-fluorophenylboronic acid is more favorable with the Cl- versus H-terminated surface and that on Cl–Si(100) the reaction with 4-fluorophenylboronic acid is ∼55.3 kJ/mol more thermodynamically favorable than the reaction with boric acid. The computational studies were also used to demonstrate the propensity of the overall approach to form high-coverage monolayers on these surfaces, with implications for selective-area boron-based monolayer doping.

Interface modification is a promising technique for enhancing electrical parameters of Organic Field Effect Transistor (OFETs). In OFETs, self-assembled monolayer molecules are widely used for treatment dielectric/semiconductor interface layer. Modification of dielectric/semiconductor layer with SAM molecules ensures a variety of potential applications. Boronic acids with four different alkyl chain lengths (Cn-BA; n = 8, 10, 12, 14) molecules were used in this study to treat the Al2O3 dielectric surface in dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) based OFETs. Treated with SAMs improve the mobility of Al2O3 surfaces for linear and saturation regime and threshold voltages shifted from positive direction. The morphological and electrical characterizations were performed for fabricated OFET. The results show that alkyl-boronic acids SAM molecules open a new perspective for further optoelectronic applications due to its application for oxide surfaces and controllability.
