“…The sol-gel-like method used to prepare these samples was somewhat similar to the technique proposed by Liu et al [105] in which zinc acetate dihydrate and nickel acetate tetrahydrate were used as precursors. Efforts to scale up the C/NiO selective absorber have been carried out [106,107].…”

“…For the porous structures, the porosity was further induced in the ZnO layer with the addition of poly ethylene glycol (PEG) to the aforementioned ZnO sol-gel solution. Here the role of the PEG is to form an organic template to support ZnO and assist in the formation of a porous structure by inducing a phase separation between the solvent and zinc oxide adsorbed on PEG [16]. Upon subsequent annealing at 200°C, the PEG was removed and the porous ZnO layer was obtained.…”

“…Hence, ZnO is a strong candidate for an electron transport layer in inverted OPVs [15]. Though there are different methods including chemical vapor deposition and spray pyrolysis for depositing ZnO, spin-coating ZnO from the sol-gel is a highly preferred method because of its low cost, composition controllability and the ability to make homogenous films [16].…”

Microstructured porous zinc oxide (ZnO) thin film was developed and demonstrated as an electron selective layer for enhancing light scattering and efficiency in inverted organic photovoltaics. High degree of porosity was induced and controlled in the ZnO layer by incorporation of polyethylene glycol (PEG) organic template. Scanning electron microscopy, contact angle and absorption measurements prove that the ZnO:PEG ratio of 4:1 is optimal for the best performance of porous ZnO. Ensuring sufficient pore-filling, the use of porous ZnO leads to a marked improvement in device performance compared to non-porous ZnO, with 35% increase in current density and 30% increase in efficiency. Haze factor studies indicate that the performance improvement can be primarily attributed to the improved light scattering enabled by such a highly porous structure.

Yttrium-doped ZnO nanoparticles were synthesized by co-precipitation method to investigate structural, optical and antibacterial properties. X-ray diffraction analysis confirms hexagonal (wurtzite) structure with average crystallite size between 16 and 30 nm. Optical energy band gap decreaseswith increasing Y-doping concentration. ZnO nanoparticles were found to be highly effective against S. aureus and Y-doped ZnO nanoparticles against E. coli, B. subtilis and S. typhi. Undoped and Y-doped ZnO nanoparticles are good inorganic antimicrobial agents and can be synthesized by cost effective co-precipitation method. Keywords: nanoparticles, ZnO, coprecipitation, antibacterial properties. Resumo Nanopartículas de ZnO dopado com ítrio foram sintetizadas pelo método de coprecipitação para investigar as propriedades estruturais, ópticas e antibacterianas.
