Description

Technical Field

[0001] The invention relates to the technical field of solar modules, in particular to a stable PV / T solar module using a full-flow channel back plate. Background Art

[0002] Silicon solar cells are made of large-area PN junctions made of silicon semiconductor materials, which are connected in series and in parallel. Metal grid lines are made on the N-type material layer as contact electrodes, and a metal film is also made on the back as a contact electrode, thus forming a solar panel. In order to reduce the loss of light emission, a layer of anti-reflection film is generally covered on the surface. They are mainly single-crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. Solar photovoltaic / thermal (PV / T) technology is a new technology that combines photovoltaics and photothermal to achieve a higher solar energy utilization rate. The photoelectric conversion power of silicon solar cells is inversely proportional to the temperature of the cell itself within a certain range.
