Description
Verfahren zur Herstellung mit dünnen Drähten bewickelter Selen- o. dgl. Zellen unter Erwärmung Es ist bekannt, daß lichtelektrische Zellen, z. B. Selenzellen, in der Weise hergestellt werden, daß man Isolierkörper mit zwei gegeneinander isolierten Drahtwicklungen versieht und durch eine Selenschicht diese Wicklungen miteinander verbindet. Es ist weiterhin bekannt, daß zwecks Empfindlichmachen das Selen bzw. solche Zellen auf höhere Temperaturen, etwa 22o° und darüber, gebracht werden müssen.Process for the production of selenium or similar wound with thin wires. Like. cells under heating It is known that photoelectric cells, e.g. B. selenium cells, be made in such a way that insulating body with two insulated against each other Wire windings provide these windings with one another through a layer of selenium connects. It is also known that selenium resp. such cells have to be brought to higher temperatures, about 220 ° and above.
Es hat sich nun gezeigt, daß die Herstellung kurzschlußfreier Wicklungen obiger Art Schwierigkeiten bereitet, denn bei der nachfolgenden Wärmebehandlung entstehen durch Wärmeausdehnung der Wicklung in der Regel Kurzschlüsse. Besonders geltend macht sich diese Schwierigkeit, wenn man mit verhältnismäßig dünnen Drähten arbeitet, zumal da durch Anspannung beim Aufwickeln wegen der größeren Reißbarkeit des Drahtes von vornherein nicht eine so hohe Festigkeit der Wicklung erreichbar ist, wie dies mitunter bei stärkerem Material der Fall ist.It has now been shown that the production of short-circuit-free windings of the above type causes difficulties, because in the subsequent heat treatment Short circuits are usually caused by thermal expansion of the winding. Particularly This difficulty asserts itself when one works with relatively thin wires works, especially because of tension when winding because of the greater tearability of the wire cannot achieve such a high winding strength from the outset is, as is sometimes the case with thicker material.
Es ist bereits für die Herstellung von Drahtzellen vorgeschlagen, das als Träger für das Selen und den Draht dienende Täfelchen und die Drähte selbst während des Bewicklungsprozesses etwas zu erwärmen, weil sich dann die Drähte in die Selenschicht, .die sie teilweise schmelzen, einbetten und bei der nachherigen Präparation nicht so leicht verschieben können. Jedoch besteht auch hier die Gefahr, daß bei der nachträglichen Erhitzung auf höhere Temperatur die Drähte infdlge der Wärmeausdehnung die Spannung verlieren und eine gegenseitige Berührung der Drähte eintritt.It has already been proposed for the manufacture of wire cells, the tablet serving as a carrier for the selenium and the wire and the wires themselves to warm up a little during the wrapping process, because then the wires are in the selenium layer, which they partially melt, embed and the subsequent one Can not move the preparation so easily. However, there is also the risk here that with the subsequent heating to a higher temperature the wires infdlge the Thermal expansion lose tension and mutual contact of the wires entry.
Erfindungsgemäß lassen sich diese Schwierigkeiten bei der Herstellung mit dünnen Drähten bewickelter Selen- o. dgl. Zellen unter Erwärmung dadurch vermeiden, daß die Bewicklung bei der der nachfolgenden Wärmebehandlung (Sensibilisation) entsprechenden Temperatur vorgenommen wird. Dabei ist es gleichgültig, auf welche Weise diese Temperaturerhöhung bzw. Wärmezufuhr stattfindet. Auch ist es gleichgültig, ob nur der Draht oder zweckmäßig der Trägerkörper oder alle beide zugleich erwärmt werden.According to the invention, these difficulties in manufacture can be eliminated Avoid warming selenium or similar cells wrapped with thin wires by doing this, that the wrapping corresponds to the subsequent heat treatment (sensitization) Temperature is made. It does not matter in which way this increase in temperature or heat supply takes place. It is also irrelevant whether only the wire or purposeful the carrier body or both are heated at the same time.
Die durch die Wärmeeinwirkung verursachten etwaigen Veränderungen, z. B. Oxydation, Anziehung von Feuchtigkeit usw., werden durch geeignete Maßregeln behoben. So kann man z. B. in indifferenten Gasatmosphären und unter Ausschluß von Feuchtigkeit u. dgl. arbeiten.Any changes caused by the effects of heat, z. B. oxidation, attraction of moisture, etc., are controlled by appropriate measures Fixed. So you can z. B. in inert gas atmospheres and with the exclusion of Humidity and the like.
