Abstract
Aluminium-doped p-type (Al-p+) silicon emitters fabricated by means of a simple screen-printing process are effectively passivated by plasma-enhanced chemical-vapour deposited amorphous silicon (a-Si). We measure an emitter saturation current density of only 246 fA/cm2, which is the lowest value achieved so far for a simple screen-printed Al-p+ emitter on silicon. In order to demonstrate the applicability of this easy tofabricate p+ emitter to high-efficiency silicon solar cells, we implement our passivated p+ emitter into an n+np + solar cell structure. An independently confirmed conversion efficiency of 19.7% is achieved using n-type phosphorus-doped Czochralski-grown silicon as bulk material, clearly demonstrating the high-efficiency potential of the newly developed a-Si passivated Al-p+ emitter.
