NOVELTY - The utility model claims a solar battery sheet and battery plate array and assembly, the solar cell comprises a battery sheet matrix. set the battery sheet basal body of the positive electrode and the battery sheet substrate back surface of the back electric field and back electrode, the battery sheet substrate comprises a silicon substrate and an anti-reflection and passivation layer of the silicon substrate surface, the solar cell further comprises a graphite conductive layer, the graphene conductive layer set on the front face of the battery sheet substrate and covering the front electrode. This utility model set graphite conductive layer by direct screen printing and high-temperature sintering silver main grid surface electrode as positive the battery sheet basal body firstly, then the battery sheet basal body, conductive layers of the graphene covering the front silver main grid, cancels the set instead of front grid line is replaced by graphite conductive layer, not only can fully collecting the carrier face of the battery sheet, also increases the area of the effective light absorption, at the same time, reduces the use of conductive silver paste so as to save cost.
