Solar battery / 2293398
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.

Method and device for converting electromagnetic radiation and method for installing oblique reflectors / 2287873
Proposed method depends on reception of direct radiation from object by solar panels in-line disposed on base and radiation re-reflected from interline pairs of flat oblique reflectors at the same time optimizing electromagnetic radiation reception conditions while object is moving; this optimization is effected when base is motionless by synchronously reducing/enhancing angle of inclination of solar panels of first like planar reflectors in each interline pair to receiving plane at the same time synchronously enhancing/reducing mentioned angles of inclination of second like planar reflectors in each interline pair. In addition, angles of inclination of like planar reflectors in each pair are enhanced/reduced by reducing/enhancing width of its first like planar reflectors at the same time enhancing/reducing width of its second like planar reflectors with total width of first and second like planar reflectors in each interline pair being retained. Device for electromagnetic radiation conversion and method for mounting oblique reflectors incorporated in this device are given in invention specification.
