Problems solved by technology

The biggest problem with this structure is that the thermal resistance between the ordinary solar cell and the copper plate is relatively large. The thickness of the adhesive 14 and the quality of the bonding directly determine the quality of heat transfer, thereby affecting the overall efficiency of solar energy utilization.

Embodiment Construction

[0021] The principle, working process and specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Fig. 2 and Fig. 4 are respectively a perspective view and a structural schematic diagram of the solar photovoltaic / photothermal combined device 1 provided by the present invention. It mainly includes an outer frame 11 , a glass cover plate 12 , a solar cell 9 , a heat collecting tube 10 and a back sealing heat insulating material 8 . The solar cell 9 of the present invention is different from common solar cells. The structure of common solar cells is as shown in Figure 5. From top to bottom, it consists of a transparent solar cell back seal film 17, an upper adhesive insulating layer 18a, a silicon cell 19, The lower adhesive insulating layer 18b and the opaque solar cell back-sealing film constitute 20 . And solar cell of the present invention compares with common solar cell, and their top four laye...

Abstract

This invention relates to a photovoltage / photoheat coupled device including a solar cell, a glass cover plate set on the cell, a heat-collecting tube under the cell and a back sealed insulation material, in which, this invention sets a heat-collecting copper plate sprayed with a light absorption layer under the lower conglutinated insulation layer of the cell to replace the opaque back sealing film of a cell, besides, tin-lead or laser continuous welding is used in the connection part between the heat-collecting copper plate and the heat-collection tube to reduce heat resistance between them.

Description

technical field [0001] The invention relates to an energy conversion device, in particular to an energy conversion device for simultaneously converting solar energy into electric energy and heat energy for domestic use, and belongs to the technical field of new energy or renewable energy. Background technique [0002] With the continuous increase of primary energy consumption and the increasing scarcity of fossil energy, the development of new energy and renewable energy has been paid more and more attention. [0003] The operating system of solar photovoltaic / photothermal combination (as shown in Figure 1) has a relatively simple structure as a whole. The most important and core component of the device is the solar photovoltaic / photothermal combination device, and the solar photovoltaic / photothermal Photovoltaic and Thermal Panel (PVT) is an energy conversion device that can simultaneously convert solar energy into electrical energy and thermal energy for domestic use. It ...
