Summary: This study presents the design and fabrication of a photoanode composed of Au/SnS/TiO2 sensitized with natural dye for dye-sensitized solar cells (DSSCs). By calcination, a layer of spherical nano-TiO2 is prepared, and a layer of nano-SnS is deposited on the TiO2 photoanode using the continuous ion layer adsorption reaction (SILAR). The sensitized Au nanoparticles exhibit enhanced localized surface plasmon resonance (LSPR) effects and electron trapping ability, resulting in improved electron mobility and reduced electron recombination in the DSSC.

Summary: Transparent dye-sensitized solar cells (DSSCs) were fabricated using two different approaches of dye adsorption, i.e., dye cocktail and sequential dye adsorption, aiming for panchromatic photon harvesting. The combination of complementary yellow-colored dye (D-131) and green-colored far-red-sensitive squaraine dye (SQ-140) was selected for improved light absorption and transparency. The stepwise co-sensitized DSSCs showed a significant improvement in photoconversion efficiency (PCE) from 3.89% to 4.50%, attributed to the suppression of inter-dye interaction and synergistic photon harvesting.
