Exploring excited states of Pt(ii) diimine catecholates for photoinduced charge separation [PDF]

, 2015
The intense absorption in the red part of the visible range, and the presence of a lowest charge-transfer excited state, render Platinum(II) diimine catecholates potentially promising candidates for light-driven applications.

Green Chemistry im Chemieunterricht: eine farbstoffsensibilisierte Solarzelle mit sicheren und leicht verfügbaren Materialien

CHEMKON, EarlyView.
Farbstoffsensibilisierte Solarzellen (Dye‐sensitized Solar Cells, DSSCs) stellen einen biomimetischen Ansatz zur Umwandlung von Sonnenlicht in elektrische Energie dar, der sich am Funktionsprinzip der Photosynthese orientiert. Trotz ihres seit den frühen 1990er‐Jahren bekannten Konzepts existieren bislang nur wenige experimentelle Zugänge, die zugleich

Outdoor Measurements of Perovskite Modules

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 679-692, June 2026.
Performance of a single junction perovskite module (total area of 0.7164 m2) during 1 year of outdoor monitoring. ABSTRACT For the PSC PV to be a competing technology with silicon and thin film PV technologies more data from field installations need to be studied and examined.
