The efficiency of a solar cell strongly depends on the interaction between incoming light beam and surface device. Any process enhances light-surface increases absorption probability light; thus, improves generated current, in turn. Generated current could be improved either by trapping or increased device thickness. Considering fabrication costs recombination losses, mechanically thin optically thick wafers are being focused terms properties. Surface texturing among other methods is an...
Abstract This study presents a comparative analysis of non-enzymatic electrochemical voltammetric sensors, utilizing phenylalanine amino acid metal complexes (M: Ni, Zn, and Co) Polyaniline (PANI) nanocomposites (NCs). The PANI: Zn(Phala)₂ NCs-based sensor detected dopamine (DA) with sensitivity 101.18 μAμM−1 cm−2. limit detection (LOD) for the was calculated as 0.391 μM. exceptional makes highly promising potential integration into biomedical test kits. To gain deeper insights structural...
Abstract In this study, we explore the effects of nitro substituents on morphology and dopamine (DOP) sensing performance polyaniline (PANI) nanocomposites (NCs). The novelty study is unique integration 2-nitro-1H-pyrrole (D9A) 3-nitro-1H-pyrrole (D9B) into PANI to develop advanced non-enzymatic voltammetric sensors, combined with machine learning for DOP sensitivity analysis. Structural morphological insights were obtained through comprehensive characterization techniques including ¹H NMR,...
The texturing of silicon surfaces is a well-known method reducing the reflection from surface crystalline Si solar cell devices. With utilization diamond wires in recent advances wafer slicing technology, for multi-crystalline wafers by traditional acid-based technique has become difficult. Metal-Assisted Etching (MAE) been shown to be promising and low-cost alternative isotropic texturing. This paper reports, first time, new single-step Ni-assisted etching obtain nano-scale porous...
Abstract In this study, metal complexes of Leucine (Leu) and Tryptophan (Trip), namely nickel(Leucine) 2 (Ni(Leu) ), zinc(Leucine) (Zn(Leu) cobalt(Leucine) (Co(Leu) copper(Leucine) (Cu(Leu) nickel(Tryptophan) (Ni(Trip) zinc(Tryptophan) (Zn(Trip) cobalt(Tryptophan) (Co(Trip) copper(Tryptophan) (Cu(Trip) were synthesized. These then utilized to fabricate nanocomposites (NCs) based on polyaniline (PANI) through a straightforward sonochemical technique. NCs used non-enzymatic electrochemical...
In this study, metal‐assisted etching (MAE) with nitric acid (HNO 3 ) as a hole injecting agent has been employed to texture multi‐crystalline silicon wafers. It was previously proven that addition of HNO enabled control surface texturing so form nano‐cone shaped structures rather than nanowires. The process parameters optimized for optically efficient have applied Fabrication p‐type Al:BSF cells carried out on textured samples thermal SiO 2 /PECVD‐SiN x stack passivation and screen printed...
Radial junction solar cells have been proposed as an alternative device geometry to conventional planar with its remarkable electrical and optical performance. In this geometry, densely packed nano/micropillars allow minority carrier collection in the radial direction shorten diffusion length p–n junction. Besides, reduced reflection from surface increased light trapping enhance cell efficiency. study, photolithography metal‐assisted etching (MAE) techniques are used form well‐ordered...
