Solar photovoltaic module

The invention provides a solar photovoltaic module capable of improving photon utilization ratio and output power. The solar photovoltaic module comprises a glass layer, multiple battery pieces arranged at intervals and a photovoltaic back plate which are arranged from the upper to lower, wherein the glass layer, the multiple battery pieces arranged at intervals and the photovoltaic back plate are connected together through an EVA adhesive film; a reflective thermal-insulating layer is arranged on the bottom surface of the photovoltaic back plate; accommodating grooves are formed in the upper surface, corresponding to the positions of the battery pieces respectively, of the reflective thermal-insulating layer; and fluorescent powder is arranged in the accommodating grooves.
