Abstract
The present invention relates to a photovoltaic module capable of active cooling. The photovoltaic module comprises, from top to bottom in turn, a glass layer (1), a first EVA layer (2), a photovoltaic cell piece layer (3), a second EVA layer (4) and a backboard, and is characterized in that the backboard is a semiconductor refrigeration device with a refrigeration function. The technical problems that the backboard of the conventional photovoltaic module is poor in heat dissipation and that the efficiency of photovoltaic cells are impacted are solved. Rapid heat dissipation of the photovoltaic modules within a short time can be realized, and the working efficiency of the photovoltaic modules is raised.
Description
Technical field
The present invention relates to a kind of photovoltaic module, particularly relate to a kind of can the photovoltaic module of active heat removal, belong to solar module technical field.
Background technology
