The stability of metal–insulator–semiconductor (MIS) solar cells against prolonged illumination was studied. The effects of photon-induced degradation on the current–voltage (I–V) and capacitance–voltage (C–V) characteristics of MIS solar cells were investigated. The results show...

A new method named Chemical Physics (CP) method was developed to produce solar grade silicon feedstock at a company in China. In this paper the characteristic of the solar grade silicon made by CP method was analysed. The results show that the purity of solar grade silicon is above 5 N and most...
