for photovoltaic materials, the silicon solar cell is the main product. three kinds of conductive pastes are used in silicon solar cells: front contact silver paste, back side silver conductor and back side bsf aluminum paste. silver paste serves as the electrodes of the battery on both sides; following the printing of back-side silver electrode on the silicon plate, aluminum paste is printed and sintered to serve as the back side electric field, improving the cell efficiency.
