摘要:
PROBLEM TO BE SOLVED: To provide a solar cell module capable of reducing refracted light generated when sunlight is made incident. SOLUTION: The solar cell module 1 includes a one-surface light reception type solar cell element 2, a front plate 3 disposed on a front side of the solar cell element 2, and a back plate 4 disposed on a back side of the solar cell element 2. The back plate 4 includes a V-shaped light reflecting plate part 7 which reflects the sunlight made incident from the front plate 3 toward the front plate 3. Here, the light reflecting plate part 7 is shaped satisfying sin -1 (1/Nb)-2°≤θb-2θa≤sin -1 (1/Nb)+10°, where θa represents the tilt angle of inclined planes 7a, 7b forming the light reflecting plate part 7, θb represents the vertical angle of inclined planes 7a, 7b, and Nb represents the absolute refractive index of the front plate 3.
