Problems solved by technology
[0014] Although the above method can take away the heat generated by the solar thermal radiation in the solar tile frame, it cannot eliminate the heat generated on the solar cell, including the heat generated by the solar thermal radiation on the cell and the heat generated during the photoelectric conversion process.
In fact, in addition to the radiant heat generated by sunlight directly irradiating the cell, since the photoelectric conversion efficiency of the solar cell is only 13%-16%, about 80% of the sunlight's light radiation is directly converted in the photoelectric conversion process. As heat, the heat generated in this photoelectric conversion process will also increase its surface temperature, thereby affecting its conversion efficiency

The invention relates to a photoelectric conversion assembly. The photoelectric conversion assembly comprises a cooling unit for cooling a solar conversion unit and an insulated heat conduction layer arranged between the solar conversion unit and the cooling unit, wherein due to the heat conduction layer, the solar conversion unit is insulated relative to the cooling unit and transfers the heat of the solar conversion unit to the cooling unit. The cooling unit for sunshine tiles provided by the invention can simultaneously cool the tile bodies and the solar conversion unit, so that the photovoltaic power generation efficiency of the solar conversion unit is ensured.
Description
technical field [0001] The present invention relates to the field of construction, in particular to an improvement on tiles, and more particularly to a tile with functions of photovoltaic power generation and photothermal treatment. Background technique [0002] Tile is an important roof waterproof material, generally fired with clay, also made of cement and other materials, and its shape is arched, flat or half cylindrical. In modern society, people's pursuit of a comfortable building thermal environment is getting higher and higher, which leads to the increasing energy consumption of building heating and air conditioning. In developed countries, building energy consumption has accounted for 30%-40% of the country's total energy consumption, which has formed a certain restrictive effect on economic development. Therefore, people hope to apply solar energy technology to buildings to reduce building energy consumption. The tiles are usually laid on the top of the building a...
