X-rays can be used to investigate quantum confinement effects on the bandgap profiles of semiconductors, allowing better light-harvesting properties to be engineered.

Solar energy can be converted to heat for warming space and water, and to electricity and chemical fuels that provide energy for use and storage.1–4 Sunlight in the near infrared, visible, and near ultraviolet regions has considerable energy (about 0.9–3.2eV per photon) and intensity. Solar energy could therefore provide a significant contribution to our electrical and chemical resources if efficient and inexpensive...
