Popis:	Four different low-temperature sintering silver pastes were utilized to make the metal grids for a-Si:H/c-Si heterojunction (SHJ) solar cells. The thermal characteristics, the microstructure and the preferential growth orientation of the four pastes were comparatively investigated between before and after sintering. The evolution of the electrical performance of the grids as well as its effects on the performance of the SHJ solar cells was also analyzed. Based on the results, we clarified some requirements on the compositions, the morphology, and the microstructure of the low-temperature Ag paste for the SHJ solar cell application. Uniformly distributed nanoscale Ag paste with suitable organic solvents should be the best.
