Solar battery module

A solar battery module having a plurality of solar battery cells embedded in an in-plane direction in a front-surface sealing member by separating the solar battery cells at a distance there between, the solar battery cells being electrically connected to each other in a filling material sandwiched between the front-surface sealing member having translucency and a back-surface sealing member, wherein

• each of the solar battery cells includes:
• a first-conductivity-type semiconductor substrate that has an impurity diffusion layer having a second-conductivity-type impurity element diffused thereon at one surface side;
• a reflection prevention film that is formed on the impurity diffusion layer;
• a first electrode that is electrically connected to the impurity diffusion layer by penetrating the reflection prevention film;
• a passivation film that is formed at another surface side of the semiconductor substrate;
• and
• a second electrode that is embedded in the passivation film and is electrically connected to the another surface side of the semiconductor substrate, and
• the back-surface sealing member is a high reflectance portion having a high reflection rate such that an average reflection rate of light of a wavelength in a range of 400 to 1200 nanometers is equal to or higher than 50% in at least a region corresponding to the solar battery cells, and
• the back-surface sealing member includes a low reflectance portion having a low reflection rate such that an average reflection rate of light of a wavelength in a range of 400 to 1200 nanometers is lower than 50%, at any position between a front surface of the reflection prevention film of the solar battery cells and the back-surface sealing member, in a region between the solar battery cells adjacent to each other or in a region corresponding to a region in a thickness direction of the solar battery module.
