Technologies and components used in the manufacture of solar heat PV modules

N. Filippchenkova, V. Panchenko

All-Russian Research Institute for Electrification of Agriculture has conducted studies for several decades of solar photovoltaic and warm photo of electrical installations. Such plants are created as in a planar implementation, and as part of a solar radiation concentrator. As sealing the encapsulating material in such solar cells photo electric heat developed modules used in two-component polysiloxane VIESH optically transparent low modulus silicone gel layer of thickness of which can vary depending on the needs and characteristics of calculated from 0.1 mm to 2 mm or more.

The purpose of research - analysis of technologies and components used in the manufacture of solar modules, electrical warm photo.

The results of research. There are a number of distinctive positive aspects of using technology encapsulation two-component compound solar cells compared to the standard lamination technology.

Energy-saving vacuum glazing can be used in the manufacture of solar modules, electrical warm photo.

Using a vacuum insulating glass solder can largely solve the problem of energy saving. In VIESH together with the electronics industry enterprises developed a fundamentally new vacuum windows with unique properties.

In the presence of the infrared coating on glasses heat resistance can be increased by 10 times compared with single glazing.

Photodetector photo electric heat solar module - absorber to the coolant channel, in which the heating of the heat carrier is made of steel. The use of aluminum as material for the absorber from the standpoint of better thermal conductivity is preferable, however, should consider the high cost of aluminum and difficulty in the manufacture thereof - aluminum amenable to welding difficult.

As an insulation material in the developed teplofotoelektricheskom module uses two sheets of transparent polycarbonate 4 mm thick, each with λsot thermal conductivity. = 0.2 W / (m • K)

To cool the solar cells in a solar heat photo electric module uses the coolant circulating in the channel photodetector - absorber.

With the onset of periods with negative ambient temperature becomes topical use antifreeze coolant circulation system.

Pre-emptive use of water is due to its high heat capacity of all fluids and a high density of the water is different from synthetic substances toxicological and environmental properties, it is absolutely safe for people.

Conclusions

At the moment, solar module production technology are quite mastered and used, and most of the research related to the study warm photo electric modules that are based on traditional solar collectors. On the other hand, there is the need for special approach to the choice of construction materials and modes of operation of the heat photovoltaic modules. In this regard, there is a need to conduct studies to improve the efficiency of the heat photo electric modules, to develop an optimal design and ability to provide photovoltaic cells work in the most favorable conditions.

Based on the above, we can conclude that the approach to the issue of selection of the main structural materials and technologies to create teplofotoelektricheskih solar modules should bring a number of important requirements for the materials and the combination of the various properties of each component given the complexity of the design of this type of solar modules.
