pH-jumps in a Protic Ionic Liquid Proceed by Vehicular Proton Transport
Sourav Maiti, Sunayana Mitra, Clinton A. Johnson +3
The dynamics of excess protons in the protic ionic liquid ethylammonium formate (EAF) have been investigated from femtosecond to microseconds using visible pump mid-infrared probe…
Generating Triplets in Organic Semiconductor Tetracene upon Photoexcitation of Transition Metal Dichalcogenide ReS
Sourav Maiti, Deepika Poonia, Pieter Schiettecatte +4
We studied the dynamics of transfer of photoexcited electronic states in a bilayer of the two-dimensional transition metal dichalcogenide ReS and tetracene, with the aim to pro…
Unraveling the Photophysics of Liquid-Phase Exfoliated Two-Dimensional ReS2 Nanoflakes
Pieter Schiettecatte, Deepika Poonia, Ivo Tanghe +6
Few-layered transition metal dichalcogenides (TMDs) are increasingly popular materials for optoelectronics and catalysis. Amongst the various types of TMDs available today, rhenium…
Emergence of New Materials for Exploiting Highly Efficient Carrier Multiplication in Photovoltaics
Sourav Maiti, Marco van der Laan, Deepika Poonia +3
In conventional solar cell semiconductor materials (predominantly Si) photons with energy higher than the band gap initially generate hot electrons and holes, which subsequently co…
Change in Tetracene Polymorphism Facilitates Triplet Transfer in Singlet Fission-Sensitized Silicon Solar Cells
Benjamin Daiber, Sourav Maiti, Silvia Ferro +8
Singlet fission in tetracene generates two triplet excitons per absorbed photon. If these triplet excitons can be effectively transferred into silicon (Si) then additional photocur…
