SOLAR CELLS WITH PLATED BACK SIDE SURFACE FIELD AND BACK SIDE ELECTRICAL CONTACT AND METHOD OF FABRICATING SAME |
摘要 |
The present disclosure provides a method of forming a back side surface field of a solar cell without utilizing screen printing. The method includes first forming a p-type dopant layer directly on the back side surface of the semiconductor substrate that includes a p/n junction utilizing an electrodeposition method. The p/n junction is defined as the interface that is formed between an n-type semiconductor portion of the substrate and an underlying p-type semiconductor portion of the substrate. The plated structure is then annealed to from a P++ back side surface field layer directly on the back side surface of the semiconductor substrate. Optionally, a metallic film can be electrodeposited on an exposed surface of the P++ back side surface layer.
