SOLAR BATTERY Russian patent published in 2007 - IPC H01L31/42 

FIELD: electrical engineering; solar-to-electric energy conversion primarily for space engineering.

SUBSTANCE: proposed solar battery has flat tubular frame with regularly disposed locations accommodating modules of solar cells whose magnetic torque is close to zero; these cells can be GaAs/Ge based and have optically transparent shielding plate on face end and shielding plate on rear end. They are interconnected into series or parallel circuits by means of conducting buses. Strings are fixed on face end of frame. Shielding plates installed on rear end are made of radiation-resistant foiled material in the form of boards whose metal-plating layer incorporates current-conducting pads and tracks. Each solar cell has current leads made in the form of buses connected to current-conducting pads of boards. Conducting buses interconnecting solar cells function to connect conducting pads of boards in adjacent solar cells; the latter are installed within module in tandem and are mechanically joined together by means of longitudinal flexible members adhered to rear plates and spaced apart through distance equal to that between their parallel strings; solar cells installed in parallel circuits of module are joined together to form minimal gaps by means of flat flexible clips. Module is fixed to strings by means of thread or wire.

EFFECT: reduced size, enhanced mechanical endurance and power capacity, simplified design, facilitated manufacture and maintenance, minimized in-process loss.
