Summary: Dye-sensitized solar cells (DSSCs) have attracted attention for their low-cost processing, ability to work in diffuse light, and potential for building integrated photovoltaics (BIPV). However, their efficiency is low due to multiple issues. This study introduces a graphene/TiO2 scattering layer that enhances electron transport and light scattering. Results show that with 0.01 wt% graphene, a 33% higher photoconversion efficiency (PCE) was achieved compared to without scattering layer. However, PCE decreases at >0.01 wt% graphene due to loss of diffuse reflectance and higher optical absorption.

Summary: In this study, a one-dimensional protrusive TiO2 strip array was fabricated using chemical and physical methods. A porous semiconductor layer was coated on the strip array. The results showed that the DSSC with the TiO2 strip array had a higher energy conversion efficiency, which can be attributed to the large surface area of the protrusive structure and its specific electron transport paths.

Summary: A 90-nm-thick TiO2 grid was fabricated using photolithography, sputtering, and lift-off process. A nanoporous film was deposited on the TiO2 grid, which induced a protrusive structure. Experimental results showed that introducing the TiO2 grid into a dye-sensitized solar cell increased its power conversion efficiency by 25%. This improvement can be attributed to the large surface area and directional electron transport channels of the protrusive structure.

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: This study focuses on using upconversion phosphors (UCPs) to convert IR into visible light to enhance the efficiency of dye-sensitized solar cells (DSSCs). The addition of an optimal amount of UCPs significantly improves the power conversion efficiency (PCE) of DSSCs, while excess UCPs deteriorate efficiency due to rapid recombination and increased interfaces.

Summary: Pure TiO2 and surface-modified TiO2 films were developed using spray pyrolysis technique, with similar crystal structure and optical absorption properties. However, the addition of ZnO layer in SMT films increased impedance and hindered reverse electron transmission. Thus, the efficiency of DSSCs improved from 8.25% to 9.3%.

Summary: The Rhodamine-6G derivative Rhd and its metal complexes with aluminum and chromium ions were synthesized and characterized using UV-vis and fluorescence spectroscopy. Dye-sensitized solar cells (DSSCs) were fabricated with Rhd and the metal complexes, and their solar-to-electric power efficiencies were determined through current-density measurements and Electrochemical Impedance Spectroscopy (EIS). The Rhd and Cr3+-sensitized solar cell showed the highest solar to electric power efficiency at 0.16%.

Summary: Co-sensitization using natural and synthetic dyes from Hibiscus sabdariffa and Rhodamine, respectively, is investigated for enhancing the performance of DSSCs. The UV-Vis absorption spectra demonstrate the overlapping absorption of the mixed dye, indicating cumulative light harvesting. DSSCs are characterized using UV-Vis Spectroscopy, SEM, FTIR, XRD, EDS, and EIS. The co-sensitized dye solar cell shows the highest Jsc of 4.02mA and power conversion efficiency of 1.23%, attributed to light harvesting and effective dye loading.
