Short description (English)

Electroplated Front Grid for Crystalline Si Hetero Junction Solar Cell

Abstract (German)

A new electroplating process for the fabrication of the front grid of hetero junction based silicon solar cells will be devel-oped, characterized, and finally transferred to the industrial partner. The challenge is to deposit the front grid metalliza-tion directly on a transparent conductive ITO layer with excellent adhesion, specified electrical performance, and good long-term reliability. The project will contribute significantly to the commercialization of hetero junction Si solar cells. Moreover, the novel approach promises an important enhancement in cell efficiency over current state-of-the-art printing technology. The project results will greatly improve Roth and Rau¿s market position as a leading supplier of fab equip-ment for the mass production of solar cells and strengthen the competence of the Roth & Rau Switzerland research center.
