Abstract： |
The invention discloses a kind of ceramic substrate multi-crystal silicon film solar energy battery and the manufacturing method. The invention deposits isolation layer and forms a p-type multi-crystal silicon film on the ceramic substrate, they dispersed to produce the p-n node, carries on laser etching to remove the n-type silicon layer on part area, the produced positive electrode is connected to the n-type silicon layer and the naked reversal electrode and p-type multi-crystal silicon film. In order to induce out the positive electrode and the negative electrode from the frontal surface of the battery, solves the problem that the ceramic substrate is insulated, the positive electrode can't be leaded out form the back surface. The material is easy to be acquired, the cost is low. |
