Interfacial Microstructures of Front-Side Ag Contact of Solar Cell with High Basicity of Tellurite Glass |
| 초록 |
Ag paste is commonly used to form contact to the n+emitter in the front electrode of silicon solar cells. The size and distribution of the Ag recrystallites formed at interface Ag electrodes/Si wafer was studied as a factor affecting ohmic contact with n+emitter. We investigated interfacial microstructures of front-side Ag contact with basicity of the different glass frits to improve the electrical characteristics of the Si solar cell. The microstructure of the glass layer at the interface of the Ag electrode and Si wafer was observed using scanning electron microscopy and transmission electron microscopy. The results showed that the electrical properties were dependent on the morphology of the interfacial structure. The addition of oxides to the glass system produced more recrystallites on the n+ emitter with a greater penetration depth into the Si wafer, resulting in an increased efficiency of the solar cell. The reactivity of glass affected the removal of the ARC and the electrical properties of the Si solar cells were influenced by the charge transport facilitated by the Ag crystallites. |
