A new set of simply structured triphenylamine-based small molecules are synthesized and evaluated as dopant-free hole transporting materials (HTMs) for high-performance perovskite solar cells (PSCs) and bulk heterojunction inverted organic solar cells (BHJ IOSCs). Surprisingly, the new amphiphilic-type HTM-1 (with internal hydrophilic groups and peripheral hydrophobic alkyl tails) showed better compatibility and performance than the actual target molecule, that is, HTM-2 in PSCs and BHJ IOSCs. Importantly, the HTM-1-based dopant-free PSCs and BHJ IOSCs exhibited high power conversion efficiencies (PCEs) of 11.45 % and 8.34 %, respectively. These performances are superior and comparable to those of standard HTMs Spiro-OMeTAD (2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene) and PEDOT:PSS (poly(3,4-ethylenedioxythiophene)/polystyrene sulfonate) in PSCs and BHJ IOSCs, respectively. The enhanced device performance of the HTM-1-based PSCs is ascribed to its strong affinity towards the perovskite, properly aligned energy levels with respect to the perovskite valence band, and excellent hole transporting behavior. In addition, the well-organized energy levels of the HTMs showed excellent compatibility in BHJ IOSCs. The new amphiphilic-type HTM-based photovoltaic devices also showed long-term air stability over 700 h. These promising results offer new and unexpected prospects for engineering the interface between the photoactive material and HTMs in PSCs and BHJ IOSCs.

Paragraph 0101-0102, (2017/07/28)
Provided are a hole transporting material for a photovoltaic device and a photovoltaic device including the same, wherein the hole transporting material is a triphenylamine derivative into which a specific substituent is introduced. The triphenylamine derivative into which the specific substituent is introduced according to the present invention is used as a material of a hole transport layer of the photovoltaic device to exhibit improved power conversion efficiency than those of the existing materials. The triphenylamine derivative into which the specific substituent is introduced according to the present invention has high hole mobility, an appropriate energy level, thermal stability, and good solubility due to a structural characteristic, and when the triphenylamine derivative is applied as the hole transporting material of the photovoltaic device, particularly, a perovskite solar cell, or an organic solar cell, excellent power conversion efficiency and device stability are exhibited as compared to the existing hole transporting material, Spiro-OMeTAD or PEDOT:PSS mixture.

We report a synthetic protocol for the synthesis of functionalized diaryl- and triarylamines under mild conditions, using a soluble, air-stable copper(I) complex, Cu(PPh3)3Br, as the catalyst and cesium carbonate as the base. Using this protocol, we were able to synthesize a tri-ortho-ester functionalized triphenylamine, which had eluded us using the palladium chemistry.
