摘要： PROBLEM TO BE SOLVED: To obtain a condensing type solar battery achieving reductions in size, weight and cost.SOLUTION: The solar battery includes: a first deflection means; a first reflector disposed in almost parallel with and separated from the first deflection means; a second deflection means having a central part disposed between the first deflection means and the first reflector in almost parallel with and separated from them and an extending part extending in an opposite direction of the first deflection means in abutment on an outer peripheral end face of the first deflection means; and a solar battery cell disposed in a position adjacent to the first reflector in an in-plane direction of the first reflector. The first deflection means scatters incident sunlight to emit it. The second deflection means deflects the sunlight scattered by the first deflection means to emit it toward the solar battery cell. The first reflector reflects the sunlight that reaches the first reflector through the second deflection means and makes it again incident on the second deflection means to condense the sunlight outgoing from the second deflection means onto a light-receiving surface of the solar battery cell.
