Dr. Laquai’s research focuses on investigating the dynamics of fundamental processes inenergy conversion systems and devices, for instance the photon-to-electron conversionin organic and hybrid perovskite solar cells, as well as energy and charge transferprocesses in photocatalytic systems and during photochemical transformations. Hisgroup studies these processes by various steady-state spectroscopies, includingspectroscopic ellipsometry, spectrophotometry, quantum yield measurements, andphotoinduced absorption spectroscopy, as well as transient all-optical and electro-opticaltechniques, for instance time-resolved photoluminescence, ultrafast pump-probetransient absorption, and time-delayed charge collection techniques, with the ultimateaim to reveal efficiency-limiting processes and to develop structure-property relations.​
