Summary: In this study, a miniature windmill generator based on dynamic semiconductor/metal Schottky triboelectric nanogenerators was designed and fabricated to generate DC electrical power by harvesting wind energy. The device achieved optimal output performance with a maximum open-circuit voltage of 0.6 V and a maximum short-circuit current of 3.6 muA at a wind speed of 7 m/s and a friction layer area of 2.5 cm2. The introduction of a lubricating material, Polyalphaolefin 4, improved the wear resistance as well as the open-circuit voltage and short-circuit current of the device. This work presents a possible strategy for fabricating miniature windmill DC-TENGs and offers a potential supplement to traditional electromagnetic windmills.

Summary: Contact electrification (or triboelectrification) is a universal phenomenon that occurs between any two materials or two phases of materials. The current output varies when different materials come into contact. The tribovoltaic effect, discovered in recent years, refers to the direct current flowing between the top electrode of a p-type semiconductor and the bottom of an n-type semiconductor when they slide against each other. This effect is caused by the generation of electron-hole pairs at the PN junction, due to the energy released from the formation of new chemical bonds at the interface during mechanical sliding. The tribovoltaic nanogenerator, based on this effect, has potential applications.

Summary: In this study, aromatic rubrene was used to modify the Si surface to improve the junction quality of PEDOT:PSS/Si hybrid solar cells. The interaction of rubrene with Si dangling bonds reduced the binding energies and increased the work function of the PEDOT:PSS film, resulting in a stronger inversion layer and higher efficiency for the solar cells. The power conversion efficiency with rubrene was found to be significantly higher compared to cells without this modification.

Summary: It has been observed that direct current can be generated through sliding a doped semiconductor or metallic electrode against another doped semiconductor due to the tribovoltaic effect. In this study, we investigate the influence of temperature on the mechanical to electric power conversion in tribovoltaic dynamic copper/silicon (Cu/Si) Schottky junctions. The effects of temperature on the short circuit current and open circuit voltage are associated with carrier generation and recombination. The results show that the power output of the tribovoltaic dynamic Cu/ heavily doped p-type Si Schottky junction can be enhanced by thermal assistance, with the peak power density increasing from 19W/m2 at room temperature to 1300W/m2 at 373K.

Summary: This study investigated the high-temperature electronic transport behavior of spin-coated PEDOT:PSS top-contact molecular ensemble junctions based on self-assembled monolayers (SAMs) of oligophenylene dithiols. It was found that the high-temperature charge transport is not dominated by the integrity of SAMs, but rather the PEDOT:PSS/SAMs contact. The contact barrier height of the PEDOT:PSS/SAMs decreased at elevated temperatures, resulting in a decrease in contact resistance and normalized resistance. Additionally, the increase in grain area of PEDOT cores after thermal treatment was also related to the high-temperature charge transport.

Summary: This study designed and synthesized an organometallic nickel complex containing thieno[3,2-b]thiophene units. Composite films of the nickel complex and polyvinylidene difluoride, prepared via a simple solution process, exhibited remarkably high n-type conductivity and air stability of the thermoelectric power factor. The introduction of thieno[3,2-b]thiophene core into the backbone of the nickel complex significantly influenced the orientation within the composite films, as indicated by grazing-incidence wide-angle X-ray diffraction analysis.
