Tungsten oxide (WO3) was inserted as an anode interfacial layer between the photoactive and top electrode in inverted polymer solar cells (PSCs) with nanocrystalline titanium dioxide electron selective layer. The device WO3 exhibited a remarkable improvement power conversion efficiency compared that without WO3, which indicated efficiently prevented recombination of charge carriers at organic/top interface. dependence performances on film thickness different metal electrodes investigated....
Molybdenum trioxide (MoO3) was inserted between the active layer and top electrode in inverted polymer solar cells (PSCs) with nanocrystalline titanium dioxide as an electron selective layer. The performances of structurally identical PSCs different electrodes (Au, Ag, Al) were investigated compared. interface MoO3 metals studied by x-ray photoelectron spectroscopy. results showed that devices are greatly improved due to incorporation open-circuit voltage is relatively insensitive choice...
Nanocrystalline TiO2 thin films were prepared by sol-gel method and then used to fabricate metal-semiconductor-metal ultraviolet photodetectors with Au Schottky contact. It was found that dark current of the fabricated devices only 1.9nA at 5V applied bias. High responsivity 199A∕W achieved when it irradiated light (λ=260nm). The low high maybe attributed effect barrier in company neutral semiconductor owing wide finger gap 20μm. show a slow time response rise 6s decay 15s. authors deduced...
Semitransparent inverted polymer solar cells were developed using thermally evaporable MoO3/Ag/MoO3 as transparent anode. The ultrathin inner MoO3 layer was introduced a buffer to improve hole collection, while the outer served light coupling enhance optical transmittance of device. dependence device performances on thickness investigated. results showed that addition improves anode compared MoO3/Ag and semitransparent devices with are improved due reduced series resistance.
Efficient semitransparent polymer solar cells (ST-PSCs) have been fabricated with one-dimensional photonic crystals (1DPCs) as a high reflector. The 1DPCs are composed of several pairs WO3 (65.8 nm)/LiF (95.5 nm). By optimizing the WO3/LiF, can reflect light back into ST-PSCs due to band gap, when reflectance range is matched absorption spectrum active layer. 8 1DPC exhibit an attractive performance. short-circuit current density (Jsc) and power conversion efficiency (PCE), respectively,...

The NW was prepared via low-temperature hydrothermal method and characterized by means of X-ray diffraction, scanning electron microscope, XPS. barrier character Ag/TiO contact researched in detail. At -5-V bias, the dark current less than 35 nA. Under irradiation...
Carbon quantum dots (Cdots) are synthesized by a simple method and introduced into active layer of polymer solar cells (PSCs). The performance doped devices was apparently improved, the highest power conversion efficiency 7.05% obtained, corresponding to 28.2% enhancement compared with that contrast device. charge transport properties, resistance, impedance, transient absorption spectrum systematically investigated explore how Cdots affect on PSCs performance. This study reveals importance...

One-dimensional (WO3/LiF)N photonic crystals (1DPCs) are deposited on the Ag cathode of semitransparent polymer solar cells to improve efficiency device. The 1DPCs with 8 pair WO3/LiF act as distributed reflectors within bandgap. Then, power conversion 2.58% is achieved and there an improvement 26.3% in when compared that conventional device without 1DPCs. average transmittance almost zero 400–600 nm wavelength range. It means light absorbed sufficiently active layer. enhanced absorption...
