Empirical Thermophotovoltaic Performance Predictions and Limits
Titilope M. Dada, Calvin M. Mestelle, Daniel J. Friedman +2
Significant progress has been made in the field of thermophotovoltaics, with efficiency recently rising to over 40% due to improvements in cell design and material quality, higher…
Suppression of Phase Separation in AlGaInAs Compositionally Graded Buffers for 1550 nm Photovoltaic Converters on GaAs
Kevin L. Schulte, John F. Geisz, Harvey L. Guthrey +3
We investigate strategies to suppress phase separation and reduce threading dislocation densities (TDD) in AlGaInAs compositionally graded buffers (CGBs) that span the lattice cons…
Large Area Near-Field Thermophotovoltaics for Low Temperature Applications
Jennifer Selvidge, Ryan M. France, John Goldsmith +3
Thermophotovoltaics, devices that convert thermal infrared photons to electricity, offer a key pathway for a variety of critical renewable energy technologies including thermal ene…
Sub-0.6 eV Inverted Metamorphic GaInAs Cells Grown on InP and GaAs Substrates for Thermophotovoltaics and Laser Power Conversion
Kevin L. Schulte, Daniel J. Friedman, Titilope Dada +6
We present inverted metamorphic Ga0.3In0.7As photovoltaic converters with sub-0.60 eV bandgaps grown on InP and GaAs substrates. The compositionally graded buffers in these devices…
Pulsed Laser Ejection of Single-Crystalline III-V Solar Cells From GaAs Substrates
Benjamin A. Reeves, Myles A. Steiner, Thomas E. Carver +3
Like many optoelectronics, the highest quality III-V solar cells start out as thin single-crystalline multilayers on GaAs substrates. Separating these device layers from their grow…
