PURPOSE: A quantum dot solar battery is provided to increase the power generating efficiency of a solar battery by preventing the surface recombination of a carrier generated by absorbing the light in the silicon solar cell. CONSTITUTION: A P+ layer is formed on the lower part of a silicon wafer(10). A passivation layer and a charge separation layer(11) are formed, on which a quantum dot(QD) is formed on the top of the silicon wafer. The surface recombination of the carrier generated by absorbing the light is prevented by the quantum dot of passivation layer and the charge separation layer. A quantum dot layer(13) is formed on the lower part of the silicon wafer. |
