We present a new transparent monolithic mesoscopic solid-state dye-sensitized solar cell based on trilamellar films of mesoscopic TiO2 nanocrystalline photoanode, a ZrO2 insulating layer and an indium tin oxide counter electrode (ITO-CE), which were screen-printed layer by layer on a single substrate. When the thickness of the ITO-CE was optimized to 2.1 μm, this very simple and fully printable...

Mesoscopic solar cells based on nanostructured oxide semiconductors are considered as a promising candidates to replace conventional photovoltaics employing costly materials. However, their overall performances are below the sufficient level required for practical usages. Herein, this study proposes an anodized Ti foam (ATF) with multidimensional and hierarchical architecture as a highly effici...

Pursuing a high power conversion efficiency with no sacrifice of cost-effectiveness has been a persistent objective for dye-sensitized solar cells (DSSCs). One promising solution to this impasse is increased light harvesting. Previous efforts in light harvesting have been made on setting blocking layers or reflecting layers, or adding a light harvester, resulting in tedious procedures without r...

Dye-sensitized solar cell (DSSC) is a promising solution to global energy and environmental problems because of its clean, low-cost, high efficiency, good durability, and easy fabrication. However, enhancing the efficiency of the DSSC still is an important issue. Here we devise a bifacial DSSC based on a transparent polyaniline (PANI) counter electrode (CE). Owing to the sunlight irradiation si...

Highly ordered anodic TiO2 nanotube arrays fabricated by electrochemical anodization were sensitized with ruthenium dye N-719 to yield dye-sensitized TiO2 nanotube solar cells. Rational surface treatments on photoanode TiO2 nanotubes markedly improved the device performance. With TiCl4 treatment, in conjunction with oxygen plasma exposure under optimized conditions, dye-sensitized TiO2 nanotube...

Current work employs dye extracted from leaves of Costus woodsonii as a new sensitizer for dye-sensitized solar cells (DSSCs). The leave was in three different solvents namely ethanol, methanol, and acetone. Extraction carried out by the freezing method. DSSCs with configuration TiO2/dye/electrolyte/Pt were assembled. dyes DSSC methanol extract has an efficiency 0.23 % short-circuit current den...

Many researchers working on the development of dye-sensitized solar cells (DSCs) continue to focus synthesis photoanode materials with high surface area, along light scattering ability enhance harvesting efficiency (LHE). Meanwhile, dye packing density, which also impacts LHE significantly, is often overlooked. Solvothermally synthesized anatase TiO2 nanoparticles (SANP) were obtained by a new ...

In the context of solar energy exploitation, dye-sensitized solar cells and dye-sensitized photoelectrosynthetic cells offer the promise of low-cost sunlight conversion and storage, respectively. In this perspective we discuss the main successes and limitations of modern computational methodologies, ranging from hybrid and long-range corrected density functionals, GW approaches and multi-refere...

Nanocrystallite aggregates are spherical assemblies of nanometer-sized crystallites and feature a size on the order of sub-micrometers. This paper reports and summarizes recent progress in nanocrystallite aggregates for applications in dye-sensitized solar cells. It emphasizes that nanocrystallite aggregates are a promising class of materials with the capability to generate light scattering, en...
