About Dr. Hubbard’s research focuses on Photovoltaic and Optoelectronic Devices, Radiation Hardened Space Power, III-V Semiconductors, and Vapor Phase Epitaxy. Our activities encompass materials synthesis, device fabrication, material and device modeling, as well as characterization both at the electrical and materials level. Specific expertise lies in vapor phase epitaxy. Abstract. Currently, most solar cells are designed for and evaluated under standard spectra intended to represent typical spectral conditions. However, no single spectrum can capture the spectral variability needed for annual energy production (AEP) calculations, and this shortcoming becomes more significant for series-connected multijunction cells as the number of junctions increases. The heterostructure of the GaAs solar cell shown in Fig. 4 was not fully optimized as a thin-film solar cell to maximize the efficiency. Unlike with a bulk-type solar cell, optimizing photon management can enhance the collection efficiency of a thin-film solar cA short base with a highly reflective back contact enables a long-wavelength photon to be absorbed near the p-n junction by Cited by: Advanced characterization of solar energy materials and novel solar cell concepts Klaus Magnus Johansen – Requires relatively thick solar cells to optimize the energy harvest. Typically – µm • More research before industrial production • Liquid phase non-vacuum deposition methods are very successful → cheap production.
Concentrator and space solar cells are typically made from direct bandgap materials (GaAs etc) and radiative recombination dominates. However, most terrestrial solar cells are made from silicon, which is an indirect bandgap semiconductor and radiative recombination is extremely low and usually neglected.
