Characterizing Fill Factor Limitations in Perovskite-Silicon Tandem Solar Cells
Yueming Wang, Nan Sun, Chris Dreessen +4
Perovskite-silicon tandem technology has exceeded the single junction theoretical efficiency limit. However, there is still distance to the thermodynamic limit mainly caused by the…
Towards a fully differentiable digital twin for solar cells
Marie Louise Schubert, Houssam Metni, Jan David Fischbach +18
Maximizing energy yield (EY) - the total electric energy generated by a solar cell within a year at a specific location - is crucial in photovoltaics (PV), especially for emerging…
Phonon Decoherence of Quantum Dots in Photonic Structures: Broadening of the Zero-Phonon Line and the Role of Dimensionality
Petru Tighineanu, Chris L. Dreeßen, Christian Flindt +2
We develop a general microscopic theory describing the phonon decoherence of quantum dots and indistinguishability of the emitted photons in photonic structures. The coherence is f…
Indistinguishable and efficient single photons from a quantum dot in a planar nanobeam waveguide
Gabija Kiršanskė, Henri Thyrrestrup, Raphaël S. Daveau +16
We demonstrate a high-purity source of indistinguishable single photons using a quantum dot embedded in a nanophotonic waveguide. The source features a near-unity internal coupling…
