In addition, it is possible to obtain the heat energy obtained from the heat collector by the air pin, and to obtain the air heat energy by sucking the outside air and form the liquid pipe on the air pin, And a composite type PVT module having the function of a composite type collector.
In a residential space such as a house or a space such as an office or a factory, the cooling of the summer and the heating of the winter are emerging as the main living environment factors. Recently, the use of renewable energy has been expanded in various countries It is true.
Renewable energy refers to energy in various fields such as solar energy, geothermal energy, marine energy, bio energy, and wind energy. Among them, solar energy is a promising energy field widely used in renewable energy. However, these energies are low in energy density and have many limitations in their utilization due to inconsistencies in heat source and load.
To reduce these constraints, renewable energy facilities are usually used in conjunction with fossil fuels. However, as the new and renewable energy technology has been developed recently, technologies for improving energy efficiency by utilizing various new and renewable energy have been developed. The present invention also relates to a technology for utilizing solar energy, solar heat, .
In order to utilize this fusion compound technology, the photovoltaic / thermal (PVT) system is used for the simultaneous production of electricity and thermal energy through the joining of the photovoltaic (PV) conversion module on the upper surface of the solar collector As such, systems are being developed that enable efficient utilization of solar energy per unit area compared to conventional solar energy utilization systems (solar collectors, PV modules).
It can be formed as an energy accumulation module in which a conventional PV module and a collector are integrated into one, and the surface optical characteristics of the conventional PV module are structurally inappropriate from the viewpoint of absorbing heat energy.
In addition, PV modules are required to develop a structure that increases the heat efficiency of the PV module because the power generation efficiency is lowered depending on the temperature, and technological development is required to simultaneously improve the solar efficiency and solar thermal efficiency.
As shown in FIG. 1, the optical characteristics of conventional PV modules show a sunlight reflectance of 50% or more in a wavelength range of 1200 nm or more. These characteristics are ideal characteristics for existing PV modules, but they are somewhat unreasonable in terms of thermal energy acquisition of PVT composite modules. As a result, the heat collection efficiency of the solar photovoltaic module is lowered due to the increase of the heat radiation loss of the heat energy from the viewpoint of low acquisition.
SUMMARY OF THE INVENTION The present invention has been conceived to solve the above problems, and an object of the present invention is to provide a thin film coating for controlling the selective reflectivity of light on the surface of a PV module (glass substrate surface) And maintains the emissivity at around 20% in the infrared region, thereby minimizing the deterioration of the power generation efficiency of the PVT complex system and maximizing the thermal energy acquisition efficiency.
In addition, the existing composite module (PVT) is designed to be liquid or pneumatic in terms of thermal energy acquisition and can be applied to a limited range of applications. In contrast, the developed product has air pins And a liquid passageway is formed in the air pin so as to simultaneously heat the air and the liquid so that the energy thus obtained can be directly used to the air load or the heat of the heated liquid can be supplied to the heating and hot- Can be used in combination. In particular, the present invention is to provide a hybrid system in which the temperature of a PV module can be lowered when there is no thermal energy load in the summer, thereby increasing the electric power generation efficiency at the same time.
Other objects and advantages of the present invention will be described hereinafter and will be understood by the embodiments of the present invention. Further, the objects and advantages of the present invention can be realized by the means and the combination shown in the claims.
In order to solve the above-mentioned problems, the present invention provides a semiconductor device, A PV module for receiving sunlight transmitted through the permeable body and a heat collecting plate for absorbing solar heat are formed; A metal thin film coating structure in which an oxide, a metal complex, and an oxide are sequentially coated is attached to an upper surface of the PV module; A PV module having a surface coating for increasing the solar absorption efficiency and a solar / heat collection module structure including the same.
As described above, according to the present invention, a metal thin film coating is formed on the surface of a PV module of solar light to increase the heat collecting efficiency of the collector of the PVT complex system, thereby increasing the thermal energy efficiency and increasing the radiation efficiency of the PV module, It has the effect of increasing the solar power generation efficiency.
Further, by forming air pins on the heat collecting plates and forming liquid passages on the air pins, air energy and liquid energy can be simultaneously obtained, and a heat source suitable for the load of the target building is acquired and utilized, .
In the summer, the temperature of the overheated PV module can be reduced through the air pin attached to the back of the module, which can contribute to the improvement of power generation efficiency of the summer PV module.
