Thiophene-linked porphyrin derivatives for dye-sensitized solar cells.
Three novel organic dyes based on porphyrin derivatives were designed and synthesized for dye-sensitized solar cells, resulting in a maximum power conversion efficiency (eta) of 5.14% and a maximum IPCE value of 72% for a cell based on the dye.
متن کاملDye-sensitized solar cells using ethynyl-linked porphyrin trimers.
Toward the extension of the light-harvesting region of sensitizers in dye-sensitized solar cells (DSSCs), two ethynyl-linked porphyrin trimers were synthesized and investigated. The zinc–freebase–zinc trimer (Zn–FbA–Zn) showed an absorption maximum at a longer wavelength than the all-zinc trimer (Zn–ZnA–Zn), although the energy level of Zn–FbA–Zn was lower than that of Zn–ZnA–Zn. The DSSCs usin...
متن کاملPorphyrin Based Dye Sensitized Solar Cells
Dye-sensitized solar cells (DSSCs) have emerged as an innovative solar energy conversion technology which provides a pathway for the development of cheap, renewable and environmentally acceptable energy production (Gledhill, Scott et al., 2005; O'Regan & Grätzel, 1991; Shaheen, Ginley et al., 2005). A typical DSSC consists of a sensitizing dye chemically anchored to a nanocrystalline wide band ...
متن کاملA fluorene-modified porphyrin for efficient dye-sensitized solar cells.
Porphyrins bearing a polyaromatic or a heterocyclic group are prepared to study their fundamental and photovoltaic properties. Solar cells sensitized with a fluorene-modified porphyrin outperform other dyes in the series, reaching ~90% efficiency of N719 dye.
متن کاملTheoretical studies on the quinoidal thiophene based dyes for dye sensitized solar cell and NLO applications.
A series of quinoidal thiophene based dye molecules were designed and their optoelectronic properties were studied for dye sensitized solar cell (DSSC) applications. The efficiency of the designed dye molecules was analyzed using various parameters such as the HOMO-LUMO energy gap, absorption spectra, light harvesting efficiency (LHE), exciton biding energy (Eb) and free energy change for elect...
