Back contact solar cells including rear surface structures and methods for making same. The rear surface has small contact areas through at least one dielectric layer, including but not limited to a passivation layer, a nitride layer, a diffusion barrier, and/or a metallization barrier. The dielectric layer is preferably screen printed. Large grid areas overlay the dielectric layer. The methods provide for increasing efficiency by minimizing p-type contact areas and maximizing n-type doped regions on the rear surface of a p- type substrate.

L'invention porte sur des photopiles à contact arrière comprenant des structures de surface arrière et sur des procédés de fabrication associés. La surface arrière présente des zones de contact petites à travers au moins une couche diélectrique, comprenant, entre autres, une couche de passivation, une couche de nitrure, une couche de diffusion, et/ou une couche de métallisation. La couche diélectrique est, de préférence, sérigraphiée. De grandes zones de grilles recouvrent la couche diélectrique. Ces procédés fournissent une meilleure efficacité par minimisation des zones de contact de type p et par maximisation des zones dopées de type n sur la surface arrière d'un substrat de type p.
