Achieving Efficient p-Type Organic Thermoelectrics by Modulation of Acceptor Unit in Photovoltaic π-Conjugated Copolymers

Junhui Tang et al.

Summary: In this study, a series of D-A semiconducting copolymers with various electron-deficient A-units were systematically investigated for efficient OTEs. The relationship between thermoelectric characteristics and the electron-withdrawing ability of A-unit was elucidated through p-type doping, highlighting the importance of the strong D-A nature and highly electron-deficient A-unit in enhancing Seebeck coefficient while impacting doping efficiency and electrical conductivity. Ultimately, a high peak power factor and outstanding Seebeck coefficient were achieved in a paradigm OPV donor, demonstrating great potential in wearable electronics driven by a small temperature gradient.

Controlling the Formation of Charge Transfer Complexes in Chemically Doped Semiconducting Polymers

Dane A. Stanfield et al.

Summary: The study focuses on the chemical doping of conjugated polymers and demonstrates how adjusting the casting solvent for the dopant can control the formation of charge transfer complexes (CTCs) and integer charge transfer (ICT). By using different solvent blends, the relative amount of CTCs between P3HT and F(4)TCNQ can be readily controlled, and even in high-crystallinity materials, fractional charge transfer still occurs to some extent.

Achieving Efficient n-Doping of Conjugated Polymers by Molecular Dopants

Yang Lu et al.

Summary: Molecular doping is a central proposition in organic electronics, involving intermolecular charge transfer between organic conjugated materials and molecular dopants. While there is a focus on improving p-doping efficiency and electrical conductivity, the development of n-type molecular doping lags behind. Efficient p- and n-type molecular doping are both essential for organic electronic devices, emphasizing the need to achieve efficient n-doping in conjugated polymers.

Understanding of Face-On Crystallites Transitioning to Edge-On Crystallites in Thiophene-Based Conjugated Polymers

Sung Yun Son et al.

Summary: The orientation of crystallites in semicrystalline conjugated polymer thin films significantly impacts charge transport properties. In this study, a random copolymer RP-3T demonstrated a transition from predominantly face-on to edge-on orientation during annealing. Through detailed analysis, it was found that face-on crystallites disappear at a lower temperature while edge-on crystallites continue to grow, providing insight into the transition process.

Anion-Dependent Molecular Doping and Charge Transport in Ferric Salt-Doped P3HT for Thermoelectric Application

Lili Wu et al.

Summary: The effects of different iron (III) dopants on the doping process and charge transport properties of P3HT were investigated. The results show that doping level is influenced by driving force for charge transfer and miscibility between polymer and dopant, while carrier transport is controlled by microstructure. Among the different dopants studied, FeCl3-doped P3HT film exhibited the highest electrical conductivity due to higher carrier mobility, while Fe(OTf)(3)-doped P3HT film showed the highest doping level but lower electrical conductivity.
