When reaching one! - (U-group of cells it is necessary to connect a large number of cells in series. A fault in one or more years of the cells connected in series can easily lead to the saving output of the series connected chain to reduce to zero. a reduced output from the Soleranorünun / 5 also occurs when sine individual H solar cell is partially or completely geastzt by a. shadow out of operation, which prevents the radiation energy to the CToerfläshe · represents auitrifft solar cell. In critical wall applications, for example power sources for spacecraft, a loss of power can have catastrophic effects, even for a relatively long period of time. corresponding to US Serial No. 377 605 of June 24, 1964) by the Aimelderin.

digen wiring »to connect these ait their respective solar cells; although a single diode can have a relatively low weight "its associated wiring can cause serious problems" When manufacturing large solar cell arrays using many diodes, defective diodes occur which "before the solar array is shot into the room" must be removed.

It is beneficial »to put the diodes on to be attached to the front »that is the side opposite the radiant energy source * which is easy a technician who needs to replace the diode is available.

According to the invention, the aforementioned disadvantages are eliminated by “that” a shunt diode with two terminals Connected directly to a surface at the end of a relatively thin rectangular solar cell with a conductive tape »which is the other terminal of the diode bit opposite side of the solar cell connects, so that the roughness occupied by the diode on a Is reduced and the length of the elec-

The solar cells 10 are - but with electrical insulation - arranged on a solid substrate 17, which is used as a structural support for the one Solar cells is used. The required degree of insulation can be achieved by holding hold plates on daa feete Substrate 17 are bound. Each solar cell has an electrically conductive collector strip 11, the placed at the end of the cell in electrical contact with a surface of the cell. The collector strips are connected to one another by means of a conductive strip 16 in different rows or parallel configurations, depending on the desired output potential One of its terminals 13 is in electrical contact with the connecting tend 16 arranged. The other shunt diode terminal 14 communicates with the underside of the solar cell by means of an electrical conductive tape 15 connected. Mode 12 can be designed as a micro-glass diode, possesses low QrOSe, light weight and is particularly suitable for this purpose. If this diode is now applied directly to the connecting band 16, 30 the requirement becomes a Connection wire from the collector strip to the diode terminal run out, completely eliminated.

β ο with minimal. If the diode is defective, it can never be easily removed from the front of the solar array by unsoldering the tape 15 from the diode and applying heat to the connecting tape 16, thereby separating the diode from the tape 16. The reverse process can be used to apply the replacement diode to the collector strip. Depending on the intended application it may be necessary to put in Hebenechluß be _r each solar cell parallel combination with one or two diodes. If so, many diodes may be required and the connecting wires would create a space and weight problem. Due to the arrangement proposed according to the invention, all problems arise for every purpose and every project in the case of port.
