Window layer with p doped silicon oxide for high V-oc thin-film silicon n-i-p solar cells

Christophe Ballif, Franz-Josef Haug, Jordi Escarre Palou, Céline Pahud, Rémi Biron

We investigate the influence of the oxygen content in boron-doped nanocrystalline silicon oxide films (p-nc-SiOx) and introduce this material as window layer in n-i-p solar cells. The dependence of both, optical and electrical properties on the oxygen cont ...
