      The 30 s-Pt dye-sensitized solar cell (DSSC) generates the highest efficiency about 2.72%. The DSSC efficiency decreases with the Pt film thickness. This is attributed to the reduction of the light transmittance.

      A coating of ZrO2 nanoparticles on an indium tin oxide (ITO) substrate in an alcohol and acetic acid solution forms voids that can be used to tune the effective dielectric constant of mixing layers. After tuning to be between the dielectric constant of ITO (2.5–2.0) and air (~1), the light transmission was enhanced by about eight times. A ZrO2 nanoparticle layer with high light transmission was thus fabricated for a natural pigment-sensitized solar cell. In order to set up an environmentally friendly dye-sensitized solar cell, a water-based electrolyte was used. The efficiency of the green part of Codiaeum varie pigment on the ZrO2 nanoparticle layer was 0.688%.

      The N 1s envelopes of the NCSs (3.5 at% and 2.5 at%) were fitted with three Gaussian peaks as shown in figure. The binding energies of these three peaks were located at ~398.6, ~400.9 and ~404.5 eV, respectively, and represent C–N (sp3 bonding), C = N (sp2 bonding) and N–O/N2 bonds, respectively. There is general consensus that the low-energy peak (398.6 eV) is related to C–N or C ≡ N bonds, while the high-energy peak is attributed to a C = N bond.34,42

      Organic light-emitting diodes are about to enter the stage of developing energy-saving light sources. For this purpose, a way of utilizing a liquid crystal, embedded in a microresonator, was described. The fabrication of the substrate was complementary metal oxide semiconductor compatible, the maximum electroluminescence intensity was enhanced by a factor of 3–4, and the spectral width of the emission could be reduced down to 18 nm, thereby improving the chromaticity coordinates, considerably.

      Crednerite glass-ceramic material was investigated for the first time as a hydrogen storage candidate. The average gravimetric capacity was about 16 g H2/kg, 50 g H2/kg at 473 K and 573 K, respectively, under 20 bars pressure. XRD exhibits a reduction of copper ions to copper metal beside cristobalite and manganese oxide phases after exposing to H2 at 80 K and 573 K. The reduction of Cu+2 into Cu explain the irreversibility of hydrogen adsorption process.

      A novel type of conducting polypyrrole with an interesting porous structure was developed. The polypyrrole was prepared using a facile, environmentally friendly, solid-state vapor-phase polymerization method, which is based on the direct use of solid oxidant. This method provides the feature of controlling both the pore diameter and the pore volume as a function of the reaction time. This polymer material is not only interesting for hydrogen storage but also for other gas storage applications.
