A solar cell module capable of suppressing a decrease of a light gathering function with use and offering an excellent light gathering function over a long period of time, and a photovoltaic power generation device using the solar cell module are provided. A solar cell module 1 includes a light gathering member 2 formed of a fluorescent material 7 provided in a transparent base material 6, the light gathering member 2 absorbing external light by the fluorescent material 7 and causing emitted light to propagate to be emitted from an end face 2c, and a solar cell element 3 installed on the end face 2c of the light gathering member 2, the solar cell element 3 receiving the light and generating electric power. The fluorescent material 7 in the light gathering member 2 has an increasing range in which, in a relation between its concentration and light emission intensity obtained from the light gathering member 2 with light emission of the fluorescent material 7, the light emission intensity increases as the concentration increases from zero, and the concentration of the fluorescent material 7 in the transparent base material 6 is set higher than a concentration with which the light emission intensity becomes largest in the increasing range. |
