The field of stretchable electronics has recently gained significant interest from the academic community, with a focus on producing materials that demonstrate reliable electrical performance with improved response to mechanical deformation. This review highlights the recent progress in understanding the relationships between the mechanical behavior and electrical performance of such devices. Potential solutions can take the form of intrinsically elastic polymers, polymer semiconductor/ elastomer blends and alternative engineering-oriented approaches, which are discussed herein. Trends and design strategies are beginning to manifest in this early stage of the stretchable electronics field. The development of stretchable electrical systems can provide unique applications of organic electronics.

“…Since DMSO has a strong dipole moment, a dipole–charge interaction is generated between PEDOT:PSS and DMSO, which simultaneously enhances electrical conductivity and cohesion. Furthermore, the addition of DMSO into the solution possess a strongly dissociated PSS − H + chain into PSS anion and protons; making weaker interaction with PEDOT, improving electrical conductivity . Figure a shows ambient stability of variously purified PEDOT:PSS film.…”

“…A conductive polymer, PEDOT:PSS, should be able to form a conductive passivation material because the PSS species has an excellent passivation effect, being comparable to that of high‐temperature annealed SiO 2 , [ 23 ] and PEDOT has a good conductivity, like that of ITO. [ 24 ] However, PEDOT:PSS has a core−shell structure, and after the use of a PSS dispersant to solubilize the material for assembly, the structure is composed of a conductive PEDOT core and an insulated PSS shell [ 25,26 ] ; thus, an additive, such as ethylene glycol (EG) [ 24,27 ] or dimethyl sulfoxide (DMSO), [ 28–30 ] must be used to destroy the PSS shell structure and to obtain a good conductivity. [ 30 ] However, it is noted that the additive also destroys the passivation.…”

Defect state passivation and conductivity of materials are always in opposition; thus, it is unlikely for one material to possess both excellent carrier transport and defect state passivation simultaneously. As a result, the use of partial passivation and local contact strategies are required for silicon solar cells, which leads to fabrication processes with technical complexities. Thus, one material that possesses both a good passivation and conductivity is highly desirable in silicon photovoltaic (PV) cells. In this work, a passivation‐conductivity phase‐like diagram is presented and a conductive‐passivating‐carrier‐selective contact is achieved using PEDOT:Nafion composite thin films. A power conversion efficiency of 18.8% is reported for an industrial multicrystalline silicon solar cell with a back PEDOT:Nafion contact, demonstrating a solution‐processed organic passivating contact concept. This concept has the potential advantages of omitting the use of conventional dielectric passivation materials deposited by costly high‐vacuum equipment, energy‐intensive high‐temperature processes, and complex laser opening steps. This work also contributes an effective back‐surface field scheme and a new hole‐selective contact for p‐type and n‐type silicon solar cells, respectively, both for research purposes and as a low‐cost surface engineering strategy for future Si‐based PV technologies.
