Increasing Volume in Conjugated Polymers to Facilitate Electrical Doping with Phosphomolybdic Acid

Journal Article Larrain, Felipe A. ; Fuentes-Hernandez, Canek ; Chang, Yi-Chien ; ... - ACS Applied Materials and Interfaces

Molecular p-type electrical dopants have been proven useful to fine-tune the optoelectronic properties of bulk organic semiconductors and their interfaces. In this work, the volume in polymer films and its role in solution-based electrical p-type doping using phosphomolybdic acid (PMA) are studied. The polymer film volume was controlled using two approaches. One is based on heating both the PMA solution and the film prior to immersion. The second is based on coating the polymer film with a liquid blend that contains the PMA solution and a swelling solvent. ³¹P NMR and FTIR experiments indicate that the Keggin structure appears tomore »« less

Fullerene derivative induced morphology of bulk heterojunction blends: PIPCP:PC ₆₁ BM

Journal Article Huang, Tzu-Yen ; Yan, Hongping ; Abdelsamie, Maged ; ... - RSC Advances

The performance of organic solar cells (OSCs) depends crucially on the morphology in bulk heterojunctions (BHJs), including the degree of crystallinity of the polymer and the amount of each material phase: aggregated donor, aggregated acceptor, and molecular mixed donor:acceptor phase. In this paper, we report the BHJ morphology of as-cast blend films incorporating the polymer PIPCP as the donor and [6,6]-phenyl-C₆₁-butyric acid methyl ester (PC₆₁BM) as the acceptor. Tracking the scattering intensity of PC₆₁BM as a function of PC₆₁BM concentration shows that PC₆₁BM aggregates into donor-rich domains and there is little to no phase where the PC₆₁BM and PIPCP aremore »« less

Solution-based electrical doping of semiconducting polymer films over a limited depth

Journal Article Kolesov, Vladimir A. ; Fuentes-Hernandez, Canek ; Chou, Wen -Fang ; ... - Nature Materials

Solution-based electrical doping protocols may allow more versatility in the design of organic electronic devices; yet, controlling the diffusion of dopants in organic semiconductors and their stability has proven challenging. Here we present a solution-based approach for electrical p-doping of films of donor conjugated organic semiconductors and their blends with acceptors over a limited depth with a decay constant of 10–20 nm by post-process immersion into a polyoxometalate solution (phosphomolybdic acid, PMA) in nitromethane. PMA-doped films show increased electrical conductivity and work function, reduced solubility in the processing solvent, and improved photo-oxidative stability in air. Here, this approach is applicablemore »« less

Skin-like low-noise elastomeric organic photodiodes

Journal Article Park, Youngrak ; Fuentes-Hernandez, Canek ; Kim, Kyungjin ; ... - Science Advances

Stretchable optoelectronics made of elastomeric semiconductors could enable the integration of intelligent systems with soft materials, such as those of the biological world. Organic semiconductors and photodiodes have been engineered to be elastomeric; however, for photodetector applications, it remains a challenge to identify an elastomeric bulk heterojunction (e-BHJ) photoactive layer that combines a low Young’s modulus and a high strain at break that yields organic photodiodes with low electronic noise values and high photodetector performance. Here, a blend of an elastomer, a donor-like polymer, and an acceptor-like molecule yields a skin-like e-BHJ with a Young’s modulus of a few megapascals,more »« less

Effects of particle inclusions on cracking in ultrathin barrier films

Journal Article Singh, Ankit Kumar ; Kim, Kyungjin ; Chou, Wen-Fang ; ... - Thin Solid Films

Here, the effects of particle inclusions with different mechanical properties on the development of cracks in ultra-thin barrier films have been studied. Two types of particles, alumina and poly(styrene-b-methyl methacrylate) with large differences in their elastic modulus were used, representing both hard and soft inclusions. Particles were seeded onto polyethylene naphthalate substrates and subsequently coated with atomic layer deposited Al₂O₃ as a barrier film. Ca corrosion tests used to determine the performance of the barrier films revealed that soft polymer particle inclusions severely affect the development of cracking in barrier films as compared to stiff ceramic particles.
