摘要
High-density and single-crystalline CdS nanowires were grown on fluorine-doped tin oxide (FTO)/soda-lime glass substrates using Bi catalysts via the so-called solution liquid solid (SLS) mechanism Through a series of voltage loading steps, high-quality Cu(In,Ga)Se-2(CIGS) light absorption layers were electrochemically deposited on the CdS window layers and subsequently selonized at 400 degrees C to form photovoltaic cells Due to the one dimensionality and single crystallinity of the CdS nanowires, the carrier collection efficiency could be improved The resulting CIGS/CdS nanowire solar cells showed a light energy conversion efficiency of similar to 6 18% under AM 1 5 conditions (I = 100 mW/cm(2)), which is similar to 28 7% higher than that of the equivalent CIGS solar cells containing chemically deposited CdS thin film as a window layer
