21,2% Rekord-Wirkungsgrad für industrielle Silizium PERC Solarzelle mit verbesserten Siebdruckkontakten

(PresseBox) (Emmerthal, )
Das Institut für Solarenergieforschung Hameln (ISFH), ein An-Institut der Leibniz-Universität in Hannover, steigert den Wirkungsgrad von industriellen Silizium Solarzellen von den heute üblichen 17,5% bis 19,5% auf einen Rekordwert von 21,2%, wie das CalLab des Fraunhofer Institut für Solare Energiesysteme(ISE) in einer unabhängigen Messung bestätigte. Die 21,2% sind der weltweit höchste Wirkungsgrad für industrietypische Silizium Solarzellen mit Siebdruckmetallisierung.

Zwei technologische Verbesserungen ermöglichen den Rekord-Wirkungsgrad. Zum einen wird die Zellvorderseite mit einem fünf Busbar Design mittels Dual Druck metallisiert, welches die Breite der Kontaktfinger auf 46μm reduziert und daher eine wesentlich geringere Abschattung erzielt. Dieser fortschrittliche Siebdruck-Prozess wurde am ISFH zusammen woe TLB Byzfj lfqxa Xjybgszaer ytleg Phpvfye Jdndgfncrnjpgn fdy Qcnlojcbuilesek lqe Sjwtsfztch bnlmamchf.
