Abstract

The TiO2 electrode has a key role in dye sensitized solar cell (DSSC) technology in the charge generation and charge transportation. The properties of TiO2 layer affect resulting efficiency of DSSC and can be controlled by printing process and chemical composition of printing paste. TiO2 pastes with different compositions of TiO2 nanoparticles, ethanol, ethyl cellulose, water, acetic acid, α-terpineol were prepared and screen printed onto the glass substrate with fluorine doped tin oxide (FTO). The TiO2 pastes for screen printing were characterized by rheological measurements and screen printed TiO2 electrodes by atomic force microscopy and UV-Vis spectroscopy. The photocurrent - voltage characteristics and efficiencies of DSSC were evaluated and compared. All prepared TiO2 pastes were suitable for screen printing with ideal rheological characteristics. The highest efficiency 0.68 % and current density ISC = 1.21 mA/cm2 reached by the DSSC based on TiO2 electrode with thickness 1.5 μm, with amount of absorbed dye 1.1 × 10-8 mol/cm2 and without visible cracks and particles aggregation. This TiO2 electrode was prepared from the paste containing 5.4 wt. % of TiO2, 65.3 wt. % of ethanol, 1.8 wt. % of ethyl cellulose, 23 wt. % of H2O and 4.5 wt. % of CH3COOH.

Abstract

Electrochemical amperometric gas sensors represent a well-established and versatile type of devices with unique features: good sensitivity and stability, short response/recovery times, and low power consumption. These sensors operate at room temperature, and therefore have been applied in monitoring air pollutants and detection of toxic and hazardous gases in a number of areas. Some drawbacks of classical electrochemical sensors are overcome by the solid polymer electrolyte (SPE) based on ionic liquids. This work presents evaluation of an SPE-based amperometric sensor from the point of view of current fluctuations. The sensor is based on a novel three-electrode sensor platform with solid polymer electrolytes containing ionic liquid for detection of nitrogen dioxide − a highly toxic gas that is harmful to the environment and presenting a possible threat to human health even at low concentrations. The paper focuses on using noise measurement (electric current fluctuation measurement) for evaluation of electrochemical sensors which were constructed by different fabrication processes: (i) lift-off and drop-casting technology, (ii) screen printing technology on a ceramic substrate and (iii) screen printing on a flexible substrate.

Abstract

Nano-SnO2 flat-type coplanar 2-Methyl-2,4-pentanediol (MPD) gas sensor arrays were fabricated by a screen-printing technique based on nano-SnO2 powders prepared by a hydrothermal method. The results show that the fabricated gas sensor arrays have good MPD gas sensing characteristics, such as good selectivity and response-recovery characteristics. Especially, they can be used for detecting the concentration of MPD gas as low as 1 ppm which is much lower than the legal concentration of 20 ppm or 25 ppm. The good sensing properties indicate that the SnO2 gas sensor arrays have great potential for on-line or portable monitoring of MPD gas in practical environments.
