Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...
In modern ultrafast optoelectronic technologies based on wide band gap insulators, the non-equilibrium dynamics of photogenerated charges plays a major role. Unravelling the mechanisms of interaction between these charge carriers and their environment is c ...
The effects of thermal disorder on the electronic properties of organic/inorganic halide perovskites were investigated using ab initio molecular dynamics simulations. It was generally found that band gap variations due to effects of thermal disorder are th ...
Organic semiconductors have recently emerged as a promising alternative to standard inorganic semiconductors for many commercial applications. Their ability to be processed from solution combined with their unique mechanical resistance paves the way for lo ...
Organic inorganic metal halide perovskites (OIHPs) has emerged as promising photovoltaic materials the latest years. Many OIHPs, however, have complex material compositions with mixed cation and halide compositions, phase mixtures, as well as beneficial re ...
A method for manufacturing a semiconducting, organic, covalent polymer network thin film is disclosed, said method comprising the steps of deposing a solution comprising azide- containing monomers and electron-deficient alkyne-containing monomers onto a re ...
We present a fragment-based decomposition analysis tool (FB-REDA) for the reorganisation energy (lambda). This tool delivers insights on how to rationally design low-lambda organic semiconductors. The contribution of the fragment vibrational modes to the r ...
Semiconductors made of earth-abundant elements, such as zinc phosphide, have the potential to substitute less abundant, highly functional compound semiconductors such as InAs or InP. Compound semiconductors in the form of nanowires could revolutionise appl ...

Ultrafast interfacial electron transfer in sensitized solar cells has mostly been probed by visible-to-terahertz radiation, which is sensitive to the free carriers in the conduction band of the semiconductor substrate. Here, we demonstrate the use of deep- ...

Monolayer jacutingaite (Pt2HgSe3) has been recently identified as a candidate quantum spin Hall system with a 0.5 eV band gap, but no transport measurements have been performed so far on this material, neither in monolayer nor in the bulk. By using a dedic ...
