The energy relay dye, 4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM), was used with a near-infrared sensitizing dye, TT1, to increase the overall power conversion efficiency of a dye-sensitized solar cell (DSC) from 3.5% to 4.5%. Th ...

We report the use of Y3+-substituted TiO2 (0.5% Y-TiO2) in solid-state mesoscopic solar cells, consisting of CH3NH3PbI3 as the light harvester and spiro-OMeTAD as the hole transport material. A power conversion efficiency of 11.2% under simulated AM 1.5 fu ...

The hydrazone semiconductor V1375 was synthesized via a simple, low-cost procedure that mimics the synthetically challenging 9,9′-spirobifluorene core of Spiro-OMeTAD and outperforms it in perovskite solar cells.

The present invention concerns a device for room temperature reverse-bias operation photo-detection. The device comprising: - a planar first electrode extending in a planar direction; - a second electrode positioned above the first electrode in a direction ...

The remarkably high open-circuit voltage of methylammonium lead iodide perovskite solar cells is investigated. Both the theoretical maximum and the real open-circuit voltage are predicted from electroluminescence and photovoltaic external quantum efficienc ...

High-efficiency flexible dye-sensitized solar cells were fabricated with a Ti-metal foil substrate for photo anode and using a Pt-electrodeposited counter electrode on ITO/polyethylene naphthalate (ITO/PEN); these devices were characterized by incident pho ...

A flexible, saddle-like, π-conjugated skeleton composed of four fused thiophene rings forming a cyclooctatetrathiophene (CoTh) with four triphenylamines (CoTh-TTPA) is presented as a hole-transporting material (HTM) for perovskite solar cells. The new HTM ...

A symmetric squaraine and its related non-symmetric structure are shown to have comparable efficiencies in DSCs, but with undoubtedly advantages in the low cost and casiness of synthesis for the symmetrical structure. ...

The invention relates to a dopant-free perovskite optoelectronic or photovoltaic device presenting molecular orbital stretching-junction, wherein the hole transport layer is a multilayer structure comprising at least two layers, each layer comprising a dif ...
