Fabrication and characterization of plastic-based flexible dye-sensitized solar cells consisting of crystalline mesoporous titania nanoparticles as photoanodes

Electrophoretic deposition of nanoscale TiO2: technology and applications

“…The total cell efficiency was found to increase from 2.36% to 4.37% after compression of the films at 100 MPa (for titania films of 11 m) [101]. The conversion efficiencies after compression of coatings of the same thickness (11 m) prepared with different titania nanoparticles were also evaluated [102]. In this case, commercial titania P90 nanoparticles (crystal size of 15.9 nm) and synthesized mesoporous titania nanoparticles (MTN, crystal size of 12. higher conversion efficiency of the MTN specimens was attributed to their smaller crystal size which led to fewer grain boundaries and defects, less charge recombination, larger dye adsorption, and stronger light scattering compared to commercial P90.…”

Dual-functional zinc oxide aggregates with reaction time-dependent morphology as the dye-adsorption layer for dye-sensitized solar cells

“…Dye sensitized solar cells (DSSCs) have drawn much attention in the last two decades because of their appealing properties, including transparency and multicolor options, potentially low production costs, and compatibility with flexible substrates [1][2][3][4][5][6]. A critically important component of DSSC is the photoanode, which consists of a mesoporous oxide semiconductor film covered by dye molecules and plays a pivotal role in converting light into electrical energy.…”

Optimization of the dye-sensitized solar cell performance by mechanical compression

“…The reduction of the thickness helps reducing the electron transport path and internal impedance [15,16]. Schematic diagram of compression effect is shown in Figure 1.…”
