摘要：通过作图的传输线法测定比接触电阻率,定量地研究硅太阳电池正面电极用银导电浆料中银粉颗粒大小和玻璃相组成对银电极/硅表面欧姆接触的影响。结果表明,随着银导电浆料中银粉颗粒尺寸的增大比接触电阻下降,形成较好的欧姆接触;当玻璃相中铅含量增加时,在一定的烧结温度下,比接触电阻率减小。
Screen-printing is widely used for low-cost Si solar ceils to realize metal/semiconductor contacts, namely ohmic contacts, which is an important factor to improve efficiency and filling factor （FF）. The measurement of specific contact resistance is a useful method to evaluate quantitatively the quality of ohmic contact. In the present work, the specific contact resistances were measured by transfer-length method （TLM） in order to study quantitatively the influence of silver particle size and glass constituents on the Ag/Si contact, in which the silver pastes were used to form the front-side grids on Si substrates. The results show that the specific contact resistance decreases with the increased silver particle size and the Pb concentration in glass to form good ohmic contacts.
