The commercially available 4000-Watt continuous-wave (CW) Erbium-doped-fiber fi ber laser, emitting at the 1567-nm wavelength where the atmosphere has high transmission, provides an opportunity for harvesting electric power at remote "off the grid" locations using a multi-module photovoltaic (PV) "receiver" panel. This paper proposes a 32-element monocrystalline thick-layer Germanium PV panel for efficient fi cient harvesting of a collimated 1.13-m-diam beam. The 0.78-m2 2 PV panel is constructed from commercial Ge wafers. For incident CW laser-beam power in the 4000 to 10,000 W range, our thermal, electrical, and infrared simulations predict 660 to 1510 Watts of electrical output at the panel temperatures of 350 to 423 K.

Abstract
The commercially available 4000-Watt continuous-wave (CW) Erbium-doped-fiber fi ber laser, emitting at the 1567-nm wavelength where the atmosphere has high transmission, provides an opportunity for harvesting electric power at remote "off the grid" locations using a multi-module photovoltaic (PV) "receiver" panel. This paper proposes a 32-element monocrystalline thick-layer Germanium PV panel for efficient fi cient harvesting of a collimated 1.13-m-diam beam. The 0.78-m2 2 PV panel is constructed from commercial Ge wafers. For incident CW laser-beam power in the 4000 to 10,000 W range, our thermal, electrical, and infrared simulations predict 660 to 1510 Watts of electrical output at the panel temperatures of 350 to 423 K.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
