Abstract

La présente invention concerne des procédés et appareils assurant une isolation d'isolant enterré pour des contacts de cellule solaire. Selon certains aspects, l'invention place un oxyde enterré sous l'émetteur d'une cellule solaire à émetteur de polysilicium. L'oxyde fournit une excellente couche de passivation sur la plupart de la surface. Des trous dans l'oxyde fournissent des zones de contact, ce qui augmente la densité de courant pour améliorer l'efficacité. L'oxyde isole les contacts du substrat, ce qui offre l'avantage d'une structure d'émetteur sélective sans nécessiter de diffusions en profondeur. L'oxyde permet en outre d'utiliser la sérigraphie sur des cellules d'émetteur creuses avancées. Le positionnement des lignes de grille à proximité des ouvertures permet également d'utiliser un émetteur très mince pour optimiser la réponse du bleu.
