Eye-safe 1.5 and 2.0 micron laser power conversion using metamorphic InGaAs photovoltaic devices

LASE
Laser power transmission at 1.5 and 2.0 microns are considered eye-safe up to 0.1 W/cm2 irradiance. Further, the atmospheric bands at these two wavelengths may provide the highest optical transmission through the atmosphere in hazy conditions.

Optimal Bandgap of GaInAsN for Integration in a Space Four-Junction Photovoltaic Cell

International Conference on Numerical Simulation of Optoelectronic Devices
We use Poisson-Drift-Diffusion simulations to optimize a dilute nitride subcell architecture for an integration in a monolithic lattice-matched 4-junction multijunction solar cell under 1-sun AM0 spectrum. We explore a way to systematically explore how a

Multijunction upper subcell cascade photovoltaics for space applications

Journal of Applied Physics, 1988
A new class of cascade high-efficiency photovoltaics designed for space-based applications is proposed. The design improves upper subcell performance and avoids electrical and optical losses associated with an intercell ohmic contact. Multijunction upper subcells reduce bulk recombination of photogenerated minority carriers by decreasing the average ...

Investigating thallium-based materials for use in multijunction photovoltaics

2011 37th IEEE Photovoltaic Specialists Conference, 2011
The optimum band placement for both multijunction photovoltaics, where layers of semiconductor materials are connected in series, and split junction photovoltaic systems, consisting of a number of physically separated solar cells, are investigated. Possible implementations of these designs are suggested, based on design constraints such as lattice ...
