Advancements in Singlet Fission Materials for Enhanced Solar Energy Conversion
Researchers from the FAU Solar, and the University of Alberta have made significant progress in developing singlet fission materials for the harnessing of solar energy in next-generation solar cells. In a recent study led by Prof. Dirk M. Guldi and Prof. Rik R. Tykwinski, a novel hexameric pentacene system was engineered to achieve notably increased […]

Controlling Interchromophore Coupling in Diamantane-Linked Pentacene Dimers To Create a “Binary” Pair
Greißel, P.M., Schroeder, Z.W., Thiel, D., Ferguson, M.J., Clark, T., Guldi, D.M., Tykwinski, R.R. J. Am. Chem. Soc. 2024, 146, 15, 10875–10888 Two isomeric pentacene dimers, each linked by a diamantane spacer, have been synthesized. These dimers are designed to provide experimental evidence to support quantum mechanical calculations, which predict the substitution pattern on the […]

Tuning the Absorption, Fluorescence, Intramolecular Charge Transfer, and Intersystem Crossing in Spiro[fluorene]acridinone
Bo, Y., Zhang, H., Li, Y., Reva, Y., Xie, L., Guldi, D.M. Angewandte Chemie, 136(13), e202313936 In this work, we prepared a series of electron donor-acceptor systems based on spiro[fluorene-9,7’-dibenzo[c,h]acridine]-5’-one (SFDBAO). Our SFDBAOs consist of orthogonally positioned fluorenes and aromatic ketones. By fine-tuning the substitution of electron-donating pyrenes, the complex interplay among different excited-state decay […]Bo, Y., Zhang, H., Li, Y., Reva, Y., Xie, L., Guldi, D.M.

Exploring Digital Twin Applications in Accelerating PV Material Research
On sunny days, up to 60% of the electricity in Germany is produced by photovoltaics (PV). This is good news to fight climate change, but the land use by large PV fields is a problem that must be addressed. PV integration is therefore gaining importance, for example in buildings and green houses, for which novel […]

A Digital Twin to Overcome Long-time Challenges in Photovoltaics
Lüer L., Peters I.M., Smith A.S., Dorschky E., Eskofier B., Liers-Bergmann F., Franke J., Sjarov M., Brossog M., Guldi D.M., Maier A., Brabec C.J. Joule 8 (2024), 1-17 The recent successes of emerging photovoltaics (PVs) are largely driven by innovations in material science. However, closing the gap to commercialization still requires significant progress to match […]
