Novel Structure

This study provides a simple and low cost method to deposit TiO2 nanoporous thin films onto the titanium mesh substrate. The flexible titanium mesh is adopted as electrodes where a novel structure of dye-sensitized solar cell (DSSC) is fabricated. The titanium mesh owns many advantages such as low resistance, cheap and high temperature tolerance. The photoanode is fabricated while the Ti mesh immersed into the alcohol solution of nanopowder of TiO2 (P25). For a better adhesion, several treatments against the titanium mesh are carried out. The photovoltaic parameters of various DSSC are discussed through the observations of TiO2 nanoporous thin films. The alcohol solution of N719 dye is used to sensitized the photovoltaic and the electrolyte is a mixture of 0.5 M LiI, 0.05 M I2 and 0.5 M 4-tert-butyl-pyridine in 3-methoxypropionitrile. With a Xenon illuminating, a flexible cell with Jsc=2.9 mA, Voc=0.5 V and F.F =0.68, η=1.02 % is obtained.

Dye-sensitized solar cell (DSSC) has big merits of simple manufacturing, low cost, and good applications. However, efficiency of DSSC is quite low compared with other solar cells based on silicon. Ability of electron delivery is important for improving the efficiency; therefore, CNT used as an electrode and transferring electrons and heat significantly easily can be highly expected to contribute to increase conversion efficiency of DSSC. In this paper, CNT was loaded on the photocatalyst of TiO2thin films in the range from 0 wt% to 0.01 wt%. CNT was treated with 60% nitric acid at 120°C for 6 hrs and performed on ball milling process for 3 hrs. Hybrid material was made of TiO2paste and CNT predispersed by mixing. To demonstrate the property of each sample, the analytical techniques including a spectrometer for transmission and surface resistance were used. The sample of higher concentration of CNT has low transmission but low resistance, besides we have researched a proper amount of CNT 0.001 wt% that can increase 1.5% conversion efficiency of DSSC.

Dye-sensitized solar cell (DSSC) using multiwalled carbon nanotube/titanium dioxide (MWCNT/TiO2) was successfully synthesized using sol-gel method. In this method, it has been performed under various acid treatments MWCNT concentration level at (a) 0.00 g, (b) 0.01 g, (c) 0.02 g, and (d) 0.03 g. Atomic force microscopy (AFM) was used to study surface roughness of the MWCNT/TiO2thin films. The average roughness results for 0.00 g, 0.01 g, 0.02 g, and 0.03 g were 10.995, 18.308, 24.322, and 25.723 nm, respectively. High resolution transmission electron microscopy (HR-TEM) analysis showned the inner structural design of the MWCNT/TiO2particles. The TiO2nanoparticles covered almost all the area of MWCNT particles. Field emission scanning electron microscopy (FESEM) gave the morphological surface structure of the thin films. The thin films formed in good distribution with homogenous design. The DSSC with MWCNT/TiO2electrode containing 0.03 g MWCNT were resulted in the highest efficiency of 2.80% with short-circuit current densityJscof 9.42 mA/cm2and open-circuit voltageVocof 0.65 V.
