The design, synthesis, and characterization of D-π-A-π-A type organic dyes as sensitizers for dye-sensitized solar cells (DSSCs)

Photoelectric Performance of Several Dithienoheterocycles Dyes and Nanocomposite of Dyes/Graphene Quantum Dots for DSSCs

“…The two lifetimes of the three dyes are all within nanosecond limits, thus electrons can be injected into the TiO 2 semiconductor conduction band effectively. [ 59,60 ]…”

Molecular Engineering of Simple Metal‐Free Organic Dyes Derived from Triphenylamine for Dye‐Sensitized Solar Cell Applications

“…However, the rarity of sources, high costs, environmental issues related to the content of heavy metals, and low molar extinction coefficients of the ruthenium complexes limited their further applications . However, advantages such as synthetic versatility, high molar extinction coefficients, low cost, and environmental friendliness of organic donor–acceptor (D–A) dyes make them particularly attractive, relative to organometallic dyes …”

“…[18,19] However,a dvantages such as synthetic versatility,h igh molar extinction coefficients, low cost, and environmental friendliness of organic donor-acceptor (D-A) dyes make them particularly attractive, relative to organometallic dyes. [20][21][22][23] The redox electrolyte is another key component for the performance of the DSCs. It affects the photovoltages of the DSCs as ar esult of the involved redox energies and kinetics related to dye regeneration.…”
