By direct numerical solution of Maxwell's equations and the semiconductor drift-diffusion
equations, we demonstrate solar-power conversion efficiencies in the 29%–30% range in …

The power conversion efficiency of single-junction silicon solar cells has increased only by
1.5% despite extensive efforts over the past two decades. The current world-record …

We demonstrate the efficacy of wave-interference-based light trapping and carrier transport
in parabolic-pore photonic-crystal, thin-crystalline silicon (c-Si) solar cells to achieve above …

To slow the rapid increase in greenhouse gas emissions, and thus slow down global
warming, a rapid transition from fossil fuels to renewable energies is crucial. In this respect …

Eine sichere Energieerzeugung, die nachhaltig ist und somit zukünftig aufrecht erhalten
werden kann, ist ein wichtiger Erfolgsfaktor für die Gesellschaft. Probleme stellt die …
