Multiplexing approaches to thermoradiative signatureless communications
Valerii Radchenkov, Peter J. Reece, Stephen P. Bremner +2
Using mid-infrared emission from semiconductor devices for covert communications remains a relatively unexplored and yet promising opportunity. The phenomenon of negative luminesce…
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…
Compositional dependence of direct transition energies in SiGeSn alloys lattice-matched to Ge/GaAs
Phoebe M. Pearce, Sheau Wei Ong, Andrew D. Johnson +2
SiGeSn ternary alloys are a candidate material system for use in solar cells and other optoelectronic devices. We report on the direct transition energies and str…
Identifying optimal photovoltaic technologies for underwater applications
Jason A. Röhr, Ed Sartor, Joel N. Duenow +12
Improving solar energy collection in aquatic environments would allow for superior environmental monitoring and remote sensing, but the identification of optimal photovoltaic techn…
Electronic and optical properties of SiGeSn alloys lattice-matched to Ge
Phoebe M. Pearce, Christopher A. Broderick, Michael P. Nielsen +2
We present a combined experimental and theoretical analysis of the evolution of the near-band gap electronic and optical properties of SiGeSn alloys lattice-m…
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…
Singlet fission and tandem solar cells reduce thermal degradation and enhance lifespan
Y. Jiang, M. P. Nielsen, A. J. Baldacchino +5
The economic value of a photovoltaic installation depends upon both its lifetime and power conversion efficiency. Progress towards the latter includes mechanisms to circumvent the…
Investigation of Carrier Recombination Dynamics of InGaP/InGaAsP Multiple Quantum Wells for Solar Cells via Photoluminescence
K. -H. Lee, K. W. J. Barnham, John S. Roberts +4
The carrier recombination dynamics of InGaP/InGaAsP quantum wells are reported for the first time. By studying the photoluminescence (PL) and time-resolved PL decay of InGaP/InGaAs…
