Abstract

High and stable lifetimes recently reported for n-type silicon materials are an important and promising prerequisite for innovative solar cells. To exploit the advantages of the excellent electrical properties of n-type Si wafers for manufacturing simple and industrially feasible high-efficiency solar cells, we focus on back junction n+np+ solar cells featuring an easy-to-fabricate full-area screen-printed aluminiumalloyed rearp+ emitter. Independently confirmed record-high efficiencies have been achieved on n-type phosphorus-doped Czochralski-grown silicon material: 18-9% for laboratory-type n+np+ solar cells (4cm2) with shadow-mask evaporated front contact grid and 17-0% for front and rear screen-printed industrial-type cells (100 cm2). The electrical cell parameters were found to be perfectly stable under illumination.
