The Effect of Hybrid Photovoltaic Thermal Device Operating Conditions on Intrinsic Layer Thickness Optimization of Hydrogenated Amorphous Silicon Solar Cells
M. J. M Pathak, K. Girotra, S. J. Harrison +1
Historically, the design of hybrid solar photovoltaic thermal (PVT) systems has focused on cooling crystalline silicon (c-Si)-based photovoltaic (PV) devices to avoid temperature-r…
Expanded microchannel heat exchanger: design, fabrication and preliminary experimental test
David C. Denkenberger, Michael J. Brandemuehl, Joshua M. Pearce +1
This paper first reviews non-traditional heat exchanger geometry, laser welding, practical issues with microchannel heat exchangers, and high effectiveness heat exchangers. Existin…
Effects on Amorphous Silicon Photovoltaic Performance from High-temperature Annealing Pulses in Photovoltaic Thermal Hybrid Devices
M. J. M. Pathak, J. M. Pearce, S. J. Harrison
There is a renewed interest in photovoltaic solar thermal (PVT) hybrid systems, which harvest solar energy for heat and electricity. Typically, a main focus of a PVT system is to c…
Effects of Substrate Temperature on Indium Gallium Nitride Nanocolumn Crystal Growth
S. Keating, M. G. Urquhart, D. V. P. McLaughlin +1
Indium gallium nitride films with nanocolumnar microstructure were deposited with varying indium content and substrate temperatures using plasma-enhanced evaporation on amorphous S…
