Abstract: A triboelectric nanogenerator (TENG) using a 3D-spacer fabric and polydimethylsiloxane (PDMS) shows great application potential for biokinetic energy harvesting and a multifunctional self-power device. In the present disclosure, a TENG with a fabric-PDMS-fabric structure is fabricated using diverse three-dimensional (3D) fabrics and PDMS. Peak-to-peak output voltages of the diverse 3D-spacer fabrics are compared. The output voltages are changed due to structures and vertical fibers. In addition, a coefficient of surface friction between PDMS and fabric improves the output voltage. TENGs using different 3D-spacer polymeric fabrics show different maximum peak-to-peak output voltage performances. This is due to the stiffness, lateral elasticity, and 3D morphology of the fabrics. It is considered that those factors including the stiffness, the lateral elasticity, and the 3D morphology influence the densities in vertical and lateral fiber-to-fiber interaction.

Abstract: The importance of architectural asymmetry is investigated to improve the output voltage of TENGs with polyester/spandex blend three-dimensional (3D) spacer fabrics. Different types of TENGs are fabricated by stacking the 3D spacer fabrics, polydimethylsiloxane (PDMS) films, and electrodes with different stack configurations. The 3D spacer fabric TENGs fabricated with higher architectural asymmetry show higher output voltages than those fabricated with lower architectural asymmetry. In particular, the TENG with the PDMS/fabric/fabric configuration shows the highest peak-to-peak output voltage among all types. An increase in the TENG output voltage is attributed to the relatively high architectural asymmetry in the device configuration and the relatively high effective density of triboelectric charge.

Abstract: Organic polymer semiconductor-based polymer solar cells (PSCs) have attracted considerable research interest due to having excellent electrical, structural, optical, mechanical, and chemical properties. In the past 20 years, considerable efforts have been made to develop PSCs. Generally, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is used as a hole transport layer (HTL) of the PSC to enhance hole extraction efficiency, but highly acidic PEDOT:PSS destroys an indium tin oxide (ITO) electrode and an active layer and thus reduces the lifetime of the device. To avoid this problem, some attempts have been made to develop inverted PSCs having different electron transport layers (ETLs). However, such a device has limited power conversion efficiency (PCE) due to low electron mobility of the ETL. Therefore, attempts have been made to enhance the PCE of inverted PSCs using indium gallium zinc oxide (IGZO) having optimized indium (In), gallium (Ga), and zinc (Zn) contents. Accordingly, inverted PSCs that have ZnO or IGZO (having varying In:Ga:Zn molar ratios) as an ETL and have an ITO/ETL/PTB7:PC71BM/MoO3/Al structure have been constructed. The PCE of the inverted PSC can be increased from 6.22% to 8.72% using IGZO having an optimized weight ratio of In, Ga, and Zn.
