PV-Einrichtung mit reduzierter Alterung

NºPublicación: DE102018216607A1 02/04/2020

Solicitante:

SIEMENS AG [DE]

Resumen de: DE102018216607A1

Die Erfindung betrifft eine Photovoltaikeinrichtung mit einer Perowskit-PV-Zelle und insbesondere die Alterung einer solchen Perowskit-PV-Zelle. Es ist vorgesehen, mit Hilfe einer Messung eines elektrischen Parameters die innere Temperatur der Perowskit-PV-Zelle bzw. ein Maß dafür zu ermitteln. Für den Fall, dass festgestellt wird, dass der entsprechende Messwert einen Schwellwert übersteigt, dass also die innere Temperatur zu hoch ist, werden die Betriebsbedingungen der Perowskit-PV-Zelle dahingehend angepasst, dass die innere Temperatur wieder absinkt. Dies kann bspw. dadurch erfolgen, dass ein Eingangswiederstand einer der Perowskit-PV-Zelle zugeordneten Leistungselektronik derart angepasst wird, dass aufgrund der entsprechend veränderten elektrischen Ströme geringere ohmsche Verluste auftreten.
