How do sub-bandgap reflectors affect the performance of PV modules?
Klaus Jäger, Jyotirmoy Mandal, Barry P. Rand +2
Sub-bandgap reflectors (SBR) can reduce the temperature of photovoltaic (PV) modules by reflecting the near-infrared region of the solar spectrum with photon energies smaller than…

How nanotextured interfaces influence the electronics in perovskite solar cells
Dilara Abdel, Jacob Relle, Thomas Kirchartz +6
Perovskite solar cells have reached power conversion efficiencies that rival those of established silicon photovoltaics. Nanotextures in perovskite solar cells scatter the incident…

Observing the galaxy environment of QSOs
Klaus J"ager, Klaus J. Fricke, Jochen Heidt
We outline our recently started program to investigate the galaxy environment of QSOs, in particular of radio-quiet objects at intermediate redshifts.
