Photoelectrochemical cell and electrolyte for this cell
TL;DR: In this paper, a photoanode consisting of at least one polycrystalline titanium dioxide layer on a conductive substrate, a counter-electrode and an electrolyte positioned between these electrodes is presented.
Journal ArticleDOI
Phenanthrene-Fused-Quinoxaline as a Key Building Block for Highly Efficient and Stable Sensitizers in Copper-Electrolyte-Based Dye-Sensitized Solar Cells.

TL;DR: Two new D-A-π-A featured sensitizers coded HY63 and HY64 are reported, which employ either benzothiadiazole or phenanthrene-fused-quinoxaline as the auxiliary electron-withdrawing acceptor moiety, and in depth studies of interfacial charge carrier dynamics show that PFQ is superior to BT in retarding charge recombination resulting in near quantitative collection of photogenerated charge carriers.
Journal ArticleDOI
Suppressed recombination for monolithic inorganic perovskite/silicon tandem solar cells with an approximate efficiency of 23%
Sanlong Wang,Pengyang Wang,Bingbing Chen,Renjie Li,Ningyu Ren,Yucheng Li,Biao Shi,Qian Huang,Mingwen Zhao,Michael Grätzel,Xiaodan Zhang +10 more
TL;DR: NiI2-treated CsPbI3-xBrx inorganic perovskite solar cells with a 1.80 eV bandgap exhibited an efficiency of 19.53% and a voltage of 1.36 eV, corresponding to a voltage deficit of 0.44 eV as discussed by the authors .
Journal ArticleDOI
Nanoclay Gelation Approach toward Improved Dye-Sensitized Solar Cell Efficiencies: An Investigation of Charge Transport and Shift in the TiO2 Conduction Band

TL;DR: This study demonstrates that nitrate-hydrotalcite nanoclay in the electrolyte not only solidifies the liquid electrolyte to prevent solvent leakage, but also facilitates the improvement in cell efficiency.
Journal ArticleDOI
Near-infrared sensitization of solid-state dye-sensitized solar cells with a squaraine dye
TL;DR: In this paper, the use of a squaraine-based dye, JD10, as a near-infrared sensitizer for solid-state dye-sensitized solar cells (ssDSCs) was reported.
