WebThis paper reports a new class of visible light water splitting photocatalysts based on a triplet–triplet annihilation (TTA) upconversion (UC) process. The TTA-UC core composed of platinum-octaethyl-porphyrin (Pt(OEP)) and 9,10-diphenylanthracene (DPA) can upconvert low energy green light to high energy blue light with a high quantum yield. WebNov 29, 2024 · Photochemical upconversion (UC) via triplet–triplet annihilation (TTA) has attracted considerable attention for its potential applications in solar energy conversion, … city bordeaux

WebHowever, many TTA-UC studies are limited to energy upconversion within the visible spectrum range. For photovoltaic cells with a higher band gap, which harvest the higher energy spectrum (UV region), an efficient Vis-to-UV upconversion is preferred. The Vis-to-UV TTA-UC system was first introduced in 2006. WebPhotocatalysis is a way to harvest solar energy, where irradiation of UV, visible, and near-infrared (NIR) radiation from the sun causes photocatalysts to generate free radicals.
