Title:
COMPOUND SEMICONDUCTOR SOLAR BATTERY
Document Type and Number:
WIPO Patent Application WO/2014/056395
Kind Code:
A1
Abstract:
Disclosed is a compound semiconductor solar battery, characterized in that a tunnel junction is inserted in the ohmic contact laminated layers of the battery, such that the conduction type of the surface of the ohmic contact layer is changed. As for the epitaxial structure disclosed in the present invention, the tunnel junction inserted in its ohmic contact layers has a smaller thickness, which will not cause an effective increase in the epitaxial cost of the battery; on the other hand, the change in the conduction type of the surface of the ohmic contact layer will enable cheaper metals to be selected and used for manufacturing chip electrodes of the battery, i.e. the production cost of the solar cell is effectively reduced while ensuring that the battery performances are maintained.
