Novel photovoltaic photo-thermal component

Abstract

The invention discloses a novel photovoltaic photo-thermal component comprising a frame, wherein a glass layer, an upper EVA layer, a battery piece layer, an organic silicon adhesive layer, a flow channel pipe layer and a profiled backplane layer are successively installed on the frame from top to bottom; the bottom of the flow channel pipe layer is provided with a plurality of first semicirculargrooves; the top of the profiled backplane layer is provided with second semicircular grooves matching the first semicircular grooves in shape one to one; the bottom of the profiled backplane layer isprovided with arc grooves matching the second semicircular grooves in shape one to one; the first semicircular grooves and the second semicircular grooves are attached to each other; the diameter ofthe arc grooves is greater than the diameter of the second semicircular grooves; the material of the organic silicon adhesive layer is composed of methyl phenyl vinyl polysiloxane and silicon dioxide;the profiled backplane layer is a coated backplane and is composed of hydrophobic fluorocarbon coating, flame-retardant modified PET, and hydrophobic fluorocarbon coating. The novel photovoltaic photo-thermal component is simple in structure and good in bonding effect. The profiled backplane layer is consistent with the concave and convex portions of the flow channel pipe layer provided with thesemicircular grooves, thereby ensuring close fitting.

Description

technical field [0001] The invention relates to the technical field of photoelectric-photothermal integration, in particular to a novel photovoltaic photothermal component. Background technique [0002] The traditional solar energy application technology photovoltaic and photothermal are separated, the conversion efficiency of photovoltaic power generation is between 8% and 15%, and the remaining 80% to 90% of heat energy is lost to the surrounding environment, which will cause the temperature of the photovoltaic module itself to continue to rise. High, studies have shown that for every 1°C increase in the operating temperature of photovoltaic modules, the conversion efficiency will decrease by an average of 0.4 to 0.5%, so many institutions try to add heat recovery components on solar panels, that is, increase heat transfer on the basis of photovoltaic modules The micro-channel combines the photovoltaic module and the micro-channel together, with a large heat transfer area ...
