Abstract/Summary:

---

Ink jet printing has emerged as an attractive method for solar cell fabrication with industry trends towards the use of thinner and more fragile silicon and finer conductor features. It is both a non-contact and fine feature printing method. Presented here are ink jettable dopant and etchant materials and a stencil printable etchant paste suitable for forming shallow/selective emitter crystalline solar cells. Cookson is working closely with Trident Industrial Ink Jet in this development effort. Jettability of the inks was tested with both a Dimatix printer and Trident industrial print heads. All inks were ink jetted onto pc-Si samples with or without SiNx ARC coating, processed and tested.
