“…Moreover, for the TIL, we can utilize any type of nano/microstructured molds, which can be sustained at thermal imprinting temperature and pressure. Herein, we utilized the microarchitectured Si as a mold, which is developed by a relatively simple and fast wet-chemical etching method . Consequently, designing the TENG device by following the TIL and wet-chemical etching techniques can definitely reduce its manufacturing cost.…”

“…Consequently, designing the TENG device by following the TIL and wet-chemical etching techniques can definitely reduce its manufacturing cost. The proposed TENG device can also be extended for the large-scale production and commercialization since the Si master molds are available for large-scale or roll-to-roll fabrication. − In TIL technique, once a Si mold is made, it can be repeatedly used for microarchitecture transfer. Therefore, investigating the electrical output performance of the TENG using microgrooved architectured PTFE (MGA-PTFE) as a triboelectric material is very beneficial in the research area of TENGs.…”

Triboelectric nanogenerator (TENG) technology is an emerging field to harvest various kinds of mechanical energies available in our living environment. Nowadays, for industrial and large-scale area applications, developing the TENG with low device processing cost and high electrical output is a major issue to be resolved. Herein, we designed a TENG with low cost by employing the microgrooved architectured (MGA)-poly(tetrafluoroethylene) (PTFE; Teflon) and aluminum as triboelectric materials with opposite tendencies. Moreover, the MGA-PTFE was fabricated by a single-step, facile, and cost-effective thermal imprinting lithography technique via micropyramidal textured silicon as a master mold, fabricated by a wet-chemical etching method. Therefore, designing the TENG device by following these techniques can definitely reduce its manufacturing cost. Additionally, the electrical output of TENG was enhanced by adjusting the imprinting parameters of MGA-PTFE. Consequently, the MGA-PTFE was optimized at an imprinting pressure and temperature of 5 MPa and 280 °C, respectively. Thus, the TENG with an optimal MGA-PTFE polymer exhibited the highest electrical output. A robustness test of TENG was also performed, and its output power was used to drive light-emitting diodes and portable electronic devices. Finally, the real application of TENG was also examined by employing it as a smart floor and object-falling detector.

“…As opposed to acidic texturized solar cells, where a mixture of hydrofluoric acid, nitric acid, and water is used, alkaline cells are texturized by hot KOH or NaOH solution [19]. Alkaline texturization is normally used for monocrystalline solar cells because the etching process leads to uniform pyramids on the surface enabling efficient coupling of the light into the solar cell material [20,21]. For mc-Si solar cells, alkaline texturization can also be used [22,23].…”

Multicrystalline solar cells break down strongly at reverse voltages well below the theoretical limit. Previous explanations were based on assuming a constant depth of the junction below the surface. In this work, preferred phosphorous diffusion at special line defects in grain boundaries is shown to lead to spikes in the p-n junctions even below flat surfaces. The curvature radii of the spherical p-n junction bending are measured by electron beam-induced current to be in the range of 300-500nm, leading to the observed type III avalanche breakdown voltages
