Silicon heterojunction (SHJ) solar cell called HIT (heterojunction with intrinsic thin-layer), developed by SANYO Ltd. in 1994 (Sawada et al., 1994), is produced by plasma enhanced chemical vapor deposition of thin hydrogenated amorphous silicon (a-Si:H) layers on both sides of a high quality crystalline silicon (c-Si) wafer. Such novel solar cell can simultaneously realize an excellent surface passivation and a p–n junction formation. Its low-temperature processes (<200 C) can prevent the degradation of bulk quality that possibly happens in high-temperature cycling processes, and compared with conventional diffused cells, a much better temperature coefficient can be obtained with a higher open-circuit voltage (Voc) (Tucci et al., 2004; Voz et al., 2006; Xu et al., 2006). Hence, HIT solar cell has attracted more and more interests all over the world.
