On the energy conversion efficiency of the bulk photovoltaic effect

Andreas Pusch, Udo Römer, Dimitrie Culcer +1

The bulk photovoltaic effect (BPVE) leads to directed photo-currents and photo-voltages in bulk materials. Unlike photo-voltages in p-n junction solar cells that are limited by car…

Integrated and Spectrally Selective Thermal Emitters Enabled by Layered Metamaterials

Yongkang Gong, Kang Li, Nigel Copner +6

Nanophotonic engineering of light-matter interaction at subwavelength scale allows thermal radiation that is fundamentally different from that of traditional thermal emitters and p…

Optoelectronic Reciprocity in Hot Carrier Solar Cells with Ideal Energy Selective Contacts

Andreas Pusch, Milos Dubajic, Michael P. Nielsen +3

Hot carrier solar cells promise theoretical power conversion efficiencies far beyond the single junction limit. However, practical implementations of hot carrier solar cells have l…

Voltage matching, étendue and ratchet steps in advanced concept solar cells

Andreas Pusch, Nicholas J. Ekins Daukes

Many advanced solar cell concepts propose surpassing the Shockley Queisser (SQ) limit by introducing multiple quasi-Fermi level separations that are arranged in series and/or in pa…

Coulomb effects on the photo-excited quantum dynamics of electrons in a plasmonic nanosphere

Alexandra Crai, Andreas Pusch, Doris E. Reiter +3

With recent experiments investigating the optical properties of progressively smaller plasmonic particles, quantum effects become increasingly more relevant, requiring a microscopi…

Dynamical calculation of third harmonic generation in a semiconductor quantum well

Stefano Guazzotti, Andreas Pusch, Doris E. Reiter +1

Non-linear phenomena in optically excited semiconductor structures are of high interest. We here develop a model capable of studying the dynamics of the photoexcited carriers, incl…
