Ruthenium complex-cored dendrimers: Shedding light on efficiency trade-offs in dye-sensitised solar cells

Synthesis and Characterization of D–D–π–A‐Type Organic Dyes Bearing Carbazole–Carbazole as a Donor Moiety (D–D) for Efficient Dye‐Sensitized Solar Cells

“…The performance of the DSSC is based not only on the absorption of the harvesting dye but also on the total amount of dye present. Dye uptakes were therefore determined by the reported method 29. It was found that the maximum uptake of each dye at equilibrium was 66.80 × 10 15 , 76.42 × 10 15 , 84.04 × 10 15 and 84.61 × 10 15 molecules cm –2 for CCT1A , CCT2A , CCT3A and CCT2PA , respectively (Figure 6, b, and Table 3).…”

Photoinduced energy and electron transfer in rubrene–benzoquinone and rubrene–porphyrin systems

“…In an idealized system, all of the chromophores are chemically bound or they are located in close proximity of one other [7]. Because reorganization energy decreases with the increase in relative donor-acceptor separation, such molecular systems are prepared by linking the synthetic chromophores covalently with a short bridge into molecular arrays [8,9], dendrimers [10], and dyads [11][12][13], placing the donor moiety in close proximity to the acceptor moiety and reducing the energy barrier for the charge transfer process. In this case, charge transfer and separation are expected to occur on the femtosecond (fs) and picosecond (ps) time scales.…”

Effect of sodium on photovoltaic properties of dye-sensitized solar cells assembled with anatase TiO2 nanosheets with exposed {001} facets

“…Apart from the research focused on the four main component: sensitizers [2,3], semiconductor photoanodes [4][5][6][7][8][9], electrolytes [10,11], and counter electrodes [12,13] of DSSCs, growing attention has been drawn to the investigation of post-treatment and preparation methods of semiconductor materials for DSSCs as they are essential in determining the chemical and physical properties of the photoanodes and, consequently, the photovoltaic properties [14,15]. Recently, an explosion of interest in the synthesis of anatase TiO 2 nanosheets with exposed reactive {0 0 1} facets has arisen as both theoretical and experimental studies indicate the {0 0 1} surface of anatase TiO 2 is much more reactive than the thermodynamically more stable {1 0 1} counterpart, which may be favorable for various applications like photovoltaic cells, photodegradation of organic molecules, and photocatalytic water splitting [16][17][18][19].…”
