摘要
A three-step H2Se/Ar/H2S reaction is used to process Cu-In-Ga metal precursors to form Cu(In, Ga)(Se, S)(2) films over 10 x 10 cm(2) substrates. The 1st selenization step gives fine microstructure with Ga accumulation near the Mo back contact, primarily in a CU9Ga4 phase. Significant grain growth with homogenous through-film Ga distribution is obtained by the 2nd Ar annealing step. The 3rd sulfization step completes the reaction process and incorporates S near the Cu(In, Ga)Se-2 surface. The resulting films show good adhesion and yielded devices with eta = 14.8% and V-OC = 612 mV.
