Conductive paste composition, preparation method and application thereof, and crystalline silicon solar cell

The embodiment of the invention discloses a conductive paste composition, a preparation method and application thereof, and a crystalline silicon solar cell. The conductive paste composition contains a silver powder and an aluminum powder, and contains a lead-boron-selenium glass frit or a bismuth-boron-selenium glass frit. The conductive paste composition can well etch a passivation film of an n-type crystalline silicon solar cell during high-temperature sintering, meanwhile, aluminum powder contained in the conductive paste composition cannot be excessively oxidized, and an electrode with good electric contact with a p-type doped emitter can be formed. Therefore, the conductive paste composition in the embodiment of the invention can be used for preparing photovoltaic devices such as an n-type crystalline silicon solar cell. 本申请的各个实施例公开了一种导电浆料组合物及其制备方法和应用、晶硅太阳能电池。该导电浆料组合物含有银粉和铝粉，并且含有铅-硼-硒玻璃料或者铋-硼-硒玻璃料。导电浆料组合物在高温烧结时能够对n型晶硅太阳能电池的钝化膜进行良好的蚀刻，并同时不会过度氧化其内含的铝粉，能够形成与p型掺杂的发射极具有良好电接触的电极。因此，本申请的实施例中的导电浆料组合物能够用于制备n型晶硅太
