Radiative transfer in luminescent solar concentrators
A luminescent solar concentrator (LSC) offers a viable solution to spectrally convert and concentrate both direct and diffuse sunlight without the need for tracking. Its potential for commercialization is currently limited by the optical performance. A det ...
2024Understanding the design principles of organic sensitizers for highly efficient dye sensitized solar cells
Abstract
The conversion of solar to electrical power has presented itself as a solution to meet the growing energy demand and replace our current fossil fuel dependence, which causes dramatic damages to the environment. At the heart of this challenge lies ...
EPFL2021Carbazol-phenyl-phenothiazine-based sensitizers for dye-sensitized solar cells
Shaik Mohammed Zakeeruddin, Felix Thomas Eickemeyer, Lukas Pfeifer, Zhongjin Shen, Dan Ren, Wei Huang, Yunfei Jiao, Yi Ding
Heteroaromatic units are commonly used as pi-spacers for sensitizers in dye-sensitized solar cells (DSSCs). Here, we investigated the influence of the pi-spacer on the photophysical properties, electrochemical properties and photovoltaic performance of car ...
ROYAL SOC CHEMISTRY2021Effect of TiO2 Photoanodes Morphology and Dye Structure on Dye-Regeneration Kinetics Investigated by Scanning Electrochemical Microscopy
Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura, Gunther Wittstock
The dye regeneration in dye-sensitized solar cells (DSSCs) is improved by optimizing the charge separation at the level of the sensitized semiconductor treatment of the mesoporous electrode by TiCl4 that passivates the surface for back electron transfer re ...
2020A 512 x 512 SPAD Image Sensor With Integrated Gating for Widefield FLIM
Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Arin Can Ülkü
In this paper, we report on SwissSPAD2, an image sensor with 512 x 512 photon-counting pixels, each comprising a single-photon avalanche diode (SPAD), a 1-b memory, and a gating mechanism capable of turning the SPAD ON and OFF, with a skew of 250 and 344 p ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019Chapter 3: Enzyme Catalysis: A Workforce to Productivity of Textile Industry
Edgard Gnansounou, Binod Parameswaran
Enzyme guided catalysis of biological reactions and their industrial synthesis is of great interest, accounting for less energy consumption, eco-friendly solutions and high substrate specificity provided by these proteins. The textile industry accounts for ...
Wiley2019Experimental demonstration of the water-holding property of three-dimensional vortices
When injecting dye into a vertical vortex generated by a commercial magnetic stirrer, one finds that dye remains captured around the vortex core over minutes, while it gets mixed with the water outside this region rather rapidly. Thus, considering its hori ...
2018Photoanode/Electrolyte Interface Stability in Aqueous Dye-Sensitized Solar Cells
O'Regan and Gratzel conceived a dye-sensitized solar cell (DSSC), which operates as an artificial photosynthetic system converting solar light into electricity. Nevertheless, it is only recently that the scientific community is focusing on truly aqueous DS ...
