Patent

CA 2759708

Solar cells of varying composition are disclosed, generally including a central substrate, conductive layer(s), antireflection layers(s), passivation layer(s) and/or electrode(s). Multifunctional layers provide combined functions of passivation, transparency, sufficient conductivity for vertical carrier flow, the junction, and/or varying degrees of anti-reflectivity. Improved manufacturing methods including single-side CVD deposition processes and thermal treatment for layer formation and/or conversion are also disclosed.

L'invention concerne des cellules solaires de composition variée, comprenant en général une ou plusieurs couches conductrices, une ou plusieurs couches anti-reflets, une ou plusieurs couches de passivation et/ou une ou plusieurs électrodes. Des couches multifonctionnelles offrent des fonctions combinées de passivation, de transparence, de conductivité suffisante pour un écoulement porteur vertical, de jonction, et/ou de degrés de variation d'anti-réflectivité. L'invention concerne également des procédés de production améliorés comprenant des processus de dépôt chimique en phase vapeur (CVD) sur un seul côté et un traitement thermique pour former et/ou transformer une couche.
