Quantifying Regeneration in Dye-Sensitized Solar Cells
TL;DR: In this paper, the authors applied a new experimental pro-tocol for determining the kinetics of the oxidation of iodide (aka dye regeneration) in dye sensitized solar cells (DSSCs) using measurements on full cells under operating conditions.
Journal ArticleDOI
Hole‐Transporting Transistors and Circuits Based on the Transparent Inorganic Semiconductor Copper(I) Thiocyanate (CuSCN) Processed from Solution at Room Temperature
Pichaya Pattanasattayavong,Nir Yaacobi-Gross,Kui Zhao,Guy Olivier Ngongang Ndjawa,Jinhua Li,Feng Yan,Brian C. O’Regan,Aram Amassian,Thomas D. Anthopoulos +8 more
TL;DR: The wide bandgap and highly transparent inorganic compound copper(I) thiocyanate (CuSCN) is used for the first time to fabricate p-type thin-film transistors processed from solution at room temperature to demonstrate low-voltage transistors with hole mobilities on the order of 0.1 cm(2) V(-1) s(-1).
Journal ArticleDOI
Kinetic competition in liquid electrolyte and solid-state cyanine dye sensitized solar cells
Sergio Tatay,Saif A. Haque,Brian C. O’Regan,James R. Durrant,Wiljan Verhees,JM Kroon,Anton Vidal-Ferran,Pablo Gaviña,Emilio Palomares +8 more
TL;DR: In this article, the photovoltaic performance of liquid electrolyte and solid-state dye sensitized solar cells, employing a squarilium methoxy cyanide dye, is evaluated in terms of interfacial electron transfer kinetics.
Journal ArticleDOI
Electric field-induced hole transport in copper(I) thiocyanate (CuSCN) thin-films processed from solution at room temperature
Pichaya Pattanasattayavong,Guy Olivier Ngongang Ndjawa,Kui Zhao,Kang Wei Chou,Nir Yaacobi-Gross,Brian C. O’Regan,Aram Amassian,Thomas D. Anthopoulos +7 more
TL;DR: The optical, structural and charge transport properties of solution-processed films of copper(I) thiocyanate (CuSCN) are investigated and found to be nano-crystalline, highly transparent and exhibit intrinsic hole transporting characteristics with a maximum field-effect mobility.
Journal ArticleDOI
Measurement of Charge-Density Dependence of Carrier Mobility in an Organic Semiconductor Blend
TL;DR: In this article, a new methodology for analyzing the charge-density dependence of carrier mobility in organic semiconductors, applicable to the low-charge-density regime (10 14 -10 17 cm -3 ) corresponding to the operation conditions of many organic optoelectronic devices, is reported.
