Defect states refer to electronic energy levels that arise from imperfections or irregularities in the crystal structure of materials, particularly in semiconductors and insulators. These ...

Prof. Norbert Koch hosted a broad discussion around approaches for exploring the energy levels of organic semiconductors, with a particular focus on interactions across interfaces. This provided a ...

Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

Energy transfer is systematically reviewed as a guiding principle for current materials and optimization strategies in perovskite solar cells. Characteristic mechanisms are identified to classify ...
