In this paper, we report the significant effects of dye loading conditions on overall light conversion efficiency zinc oxide (ZnO) film electrodes in dye-sensitized solar cells. A comparison ZnO was also made with TiO2 prepared similar conditions. It found that using a higher and lower concentration requires shorter longer immersion time, respectively, for optimal sensitization to obtain maximum efficiencies. trend electrode as well; however, smaller differences efficiencies were observed...

Abstract Nanostructured V 2 O 5 thin films have been prepared by means of cathodic deposition from an aqueous solution made and H directly on fluorine‐doped tin oxide coated (FTO) glasses followed annealing at 500°C in air, studied as film electrodes for lithium ion batteries. XPS results show that the as‐deposited contained 15% 4+ , however after all vanadium is oxidized to 5+ . The crystallinity, surface morphology, microstructures investigated XRD, SEM, AFM. excellent electrochemical...

An ultrathin TiO2 layer is successfully coated on the surface of sub-m-sized aggregates ZnO nanocrystallites through atomic deposition (ALD) technique. The core/TiO2 shell structure increases open-circuit voltage, without impairing photocurrent density and results in an increased power conversion efficiency from 5.2% to 6.3%. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made...

We report on the fabrication and electroluminescence of an n-ZnO nanorod/p-Si heterojunction. ZnO nanorods were grown p-type Si substrates employing easy low-temperature aqueous solution method. As-grown showed good crystallinity a preferable c axial orientation. Electroluminescent devices constructed using high-molecular-weight polymers as fill-in, I–V characteristics diode-like. A typical electroluminescent spectrum such n-ZnO/p-Si heterojunction under forward bias was composed narrow...

Photoelectrode made of nanocable structure ZnO nanorods (NR) coated with TiO(2) nanosheets (NSs) was investigated for CdS/CdSe quantum dot co-sensitized solar cells. NRs prepared solution reaction at 60 °C served as the backbone direct electron transport in view single crystallinity and high mobility semiconductor. Anatase NSs thickness ∼10 nm length ∼100 were assembled onto surface via a solvothermal method. It found that thin shell might have remarkable influence on sensitized cells...

CdS/CdSe quantum dot sensitized solar cells (QDSCs) have been intensively investigated; however, most of the reported power conversion efficiency (PCE) is still lower than 7% due to serious charge recombination and a low loading amount QDs.
