The production of electricity in a greener and more sustainable way by employing renewable sources is great challenge modern times. Photovoltaic systems represent an important possibility because sunlight the most abundant source. In this review article, recent studies (from 2018 to present) involving novel iron copper complexes employed as dyes Dye-Sensitized Solar Cells (DSSCs) are reported; ...

For practical applications, flexible solid-state dye-sensitized solar cells (ss-DSSCs) with high photovoltaic performance and stability are paramount. A novel iodine (I2)-free polysiloxane based highly conductive poly(ionic liquid), which acts as the lone charge transfer intermediate, is used for first time an electrolyte in 1D TiO2 nanotube photoanodes (TiO2 NT) ss-DSSCs. The I2-free polymer p...

Two sensitizers with novel structure were designed and synthetized by introducing photochromic bisthienylethene (BTE) group into the conjugated system. Thanks to the photochromic effect the sensitizers have under ultraviolet and visible light, the conjugated bridge can be restructured and the resulting two photoisomers showed different behaviors in photovoltaic devices. This opens up a new rese...

Wurtzite and kesterite Cu2ZnSnS4 (CZTS) nanocrystals were employed as counter electrode (CE) materials for dye-sensitized solar cells (DSSCs). Compared to kesterite CZTS, the wurtzite CZTS exhibited higher electrocatalytic activity for catalyzing reduction of iodide electrolyte and better conductivity. Accordingly, the DSSC with wurtzite CZTS CE generated higher power conversion efficiency (6.8...

Single crystalline anatase TiO(2) rods with dominant reactive {010} facets are directly synthesized by hydrothermally treating Cs(0.68)Ti(1.83)O(4)/H(0.68)Ti(1.83)O(4) particles. The nanosized rods show a comparable conversion efficiency in dye-sensitized solar cells (DSSCs), and a superior photocatalytic conversion of CO(2) into methane to the benchmark P25 TiO(2) nanocrystals.

The effect of terminal groups of oligomer electrolytes on the photovoltaic performance of dye-sensitized solar cells (DSSCs) have been systematically investigated to show that the terminal group plays a critical role in determining the concentration of I(3)(-), ionic conductivity, flatband potential and consequently the energy conversion efficiency.

Hierarchically macro-/mesoporous titanate tubular structures (HTT) self-assembled by nanotubes and nanosheets were fabricated by hydrothermal treatment of titanate glycolate rods in 0.1 M NaOH aqueous solution. Double-layered dye-sensitized solar cells (DSSCs) composed of a P25 nanoparticle (NP) underlayer and a tubular TiO(2) overlayer demonstrated an enhanced photovoltaic conversion efficienc...

A competitive power conversion efficiency of 7.01% is achieved for TiO2-based dye-sensitized solar cells (DSSCs) using a chemically stable and mechanically robust molybdenum di-sulfide (MoS2) counter electrode, synthesized using a simple, scalable and low-temperature wet-chemical process, owing to its good redox reaction stability.

Dye Sensitized Solar Cells (DSSCs) present a significant renewable energy source in terms of control different parameters governing flexibility, efficiency, lifetime and cost. The liquid electrolytes used inside the cells are generally responsible for leakage inefficient encapsulation related issues. These critical practical applications DSSCs. choice electrolyte medium cell should take into ac...
