Fundamental limitations of thermoradiative energy conversion
Maxime Giteau, Michela F. Picardi, Georgia T. Papadakis
Understanding the fundamental limits of various energy conversion approaches is essential for assessing their efficiency and power output. In this work, we derive general performan…
Design of narrowband infrared emitters by hybridizing guided-mode resonance structures with van der Waals materials
Mehrdad Shokooh-Saremi, Maxime Giteau, Mitradeep Sarkar +1
In this paper, narrowband emitters have been designed using particle swarm optimization (PSO) in the 10-20 μm infrared range. The device structure consists of an anisotropic α-MoO3…
Hot-carrier thermophotovoltaic systems
Kartika N. Nimje, Maxime Giteau, Georgia T. Papadakis
A thermophotovoltaic (TPV) energy converter harnesses thermal photons emitted by a hot body and converts them to electricity. When the radiative heat exchange between the emitter a…
Deep-subwavelength Phase Retarders at Mid-Infrared Frequencies with van der Waals Flakes
Michael T. Enders, Mitradeep Sarkar, Aleksandra Deeva +5
Phase retardation is a cornerstone of modern optics, yet, at mid-infrared (mid-IR) frequencies, it remains a major challenge due to the scarcity of simultaneously transparent and b…
Thermodynamic performance bounds for radiative heat engines
Maxime Giteau, Michela F. Picardi, Georgia T. Papadakis
Heat engines cannot generally operate at maximum power and efficiency, imposing a trade-off between the two. Here, we highlight the exact nature of this trade-off for engines that…
Lithography-free directional control of thermal emission
Mitradeep Sarkar, Maxime Giteau, Michael Enders +1
Blackbody thermal emission is spatially diffuse. Achieving highly directional thermal emission typically requires nanostructuring the surface of the thermally emissive medium. The…
Design rules for active control of narrowband thermal emission using phase-change materials
Maxime Giteau, Mitradeep Sarkar, Maria Paula Ayala +2
We propose an analytical framework to design actively tunable narrowband thermal emitters at infrared frequencies. We exemplify the proposed design rules using phase-change materia…
Perspective on Near-Field Radiative Heat Transfer
Mariano Pascale, Maxime Giteau, Georgia T. Papadakis
Although near-field radiative heat transfer was introduced in the 1950's, interest in the field has recently revived, as the effect promises improved performance in various applica…
Enhancement of Hot Carrier Effects and Signatures of Confinement in Terms of Thermalization Power in Quantum Well Solar Cells
Imam Makhfudz, Nicolas Cavassilas, Maxime Giteau +4
A theoretical model using electron-phonon scattering rate equations is developed for assessing carrier thermalization under steady-state conditions in two-dimensional systems. The…
Impact of excitation energy on hot carrier properties in InGaAs MQW structure
Hamidreza Esmaielpour, Laurent Lombez, Maxime Giteau +2
Hot carrier solar cells aim to overcome the theoretical limit of single-junction photovoltaic devices by suppressing the thermalization of hot carriers and extracting them through…
Resonant absorption in multilayer quantum-well and quantum-dot solar cells
Maxime Giteau, Yusuke Oteki, Kento Kitahara +3
Epitaxially-grown quantum well and quantum dot solar cells suffer from weak light absorption, strongly limiting their performance. Light trapping based on optical resonances is par…
