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 ...
Strategies for enhancing energy‑level matching in perovskite solar cells: An energy flow perspective
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 ...
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 ...
