Abstract

Es wird eine Rückkontakt-Solarzelle sowie ein Verfahren zu deren Herstellung beschrieben. Die Rückkontakt-Solarzelle weist ein Halbleitersubstrat (1) auf, an dessen Rückseiten-Oberfläche (3) Emitterbereiche (5), die von Emitterkontakten (11) kontaktiert werden, und Basisbereiche (7), die von Basiskontakten (13) kontaktiert werden, ausgebildet sind. Die Emitterbereiche und die Basisbereiche überlappen sich zumindest in Überlappungsbereichen, wobei die Emitterbereiche (5) in den Überlappungsbereichen (19) von der Rückseiten-Oberfläche der Solarzelle aus gesehen tiefer in das Halbleitersubstrat (1) hineinreichen als die Basisbereiche (7). Dadurch kann erreicht werden, dass einerseits ein großer Flächenanteil der Rückseite des Halbleitersubstrats mit einem Ladungsträger-sammelnden Emitter bedeckt sein kann, dieser Emitter jedoch zumindest teilweise im Inneren des Halbleitersubstrats (1) „vergraben' ist, so dass kein Risiko besteht, dass die Basiskontakte 13 einen Kurzschluss zu den vergrabenen Emitterbereichen (5) provozieren.
