The thinner the cover glass,
The thinner the cover glass, the higher the transmittance, thus increasing the output power of the whole module. The backsheet is made of 2.0mm-6.0mm ordinary float semi-tempered glass instead of TPT backsheet, and the glass backsheet can be perforated or not perforated according to customer requirements. No aluminum frame is needed, which has greater cost advantage than traditional modules.

AR Photovoltaic Coated Glass
The AR coated glass developed by our company is a product obtained by using the leading international technology and equipment to coat the surface of high transmittance ultra-white solar glass with a layer of transparency-enhancing film and then undergo tempering treatment. It can effectively reduce the reflection ratio on the glass surface and increase the transmission ratio, thus improving the conversion efficiency of the module and increasing the output power of the PV module, and also has the function of surface self-cleaning.
Product Overview
The transmissivity enhancement film is based on advanced nanoporous silica technology, by controlling the size and stacking morphology of silica particles, a nanoscale uniformly distributed porous nanomaterial is obtained on the surface of ultra-white glass, and the reflectivity of the film layer is reduced to about 1%, which greatly reduces the solar reflectivity and thus improves the solar transmittance, which will ultimately enhance the conversion efficiency of solar modules.
Product advantages
1,The outer surface of the glass is treated with nano-materials to form a highly efficient permeability enhancement film, which increases the transmittance by more than 2.5% compared with uncoated glass;
2,After high temperature tempering treatment, the AR film layer is firmly bonded with the glass;
3,Resistant to different climatic conditions: acid rain, salt, heat, humidity and freezing, etc;
4,After 2000 hours of aging test, the light transmission rate has no obvious decay, and the service life can be more than 25 years.
5,The film layer has self-cleaning function, which can decompose the organic pollutants attached to the surface of the module and reduce the maintenance work of the module.

Photothermal glass
Photothermal power plants are mainly divided into: 1. tower type; 2. trough type; 3. linear Fresnel; 4. dish type. In domestic applications are more often arranged in two ways: tower type and trough type. The difference between the two ways lies in the use of heat-conducting medium and the arrangement. The tower type uses molten salt or water as the heat-conducting medium, and the temperature of the molten salt medium can reach up to 560ºC, while the trough type uses heat-conducting oil as the heat-conducting medium, and the temperature of the medium can reach up to 400ºC.
The main building forms and basic principles of solar thermal power plant
Solar thermal power plant is mainly divided into: 1. tower type; 2. trough type; 3. linear Fresnel; 4. dish type
In the domestic application is more often arranged in two ways: tower type and trough type. The difference between the two ways lies in the use of heat-conducting medium and the different ways of arrangement. The tower type uses molten salt or water as the heat-conducting medium, and the temperature of its molten salt medium can reach up to 560ºC, while the trough type uses heat-conducting oil as the heat-conducting medium, and the temperature of its medium can reach up to 400ºC.
The tower type power station is built with a high tower as the center, and the heliostats are arranged in a circle around the tower, emitting sunlight to the tower heat absorber to heat the molten salt medium at the top of the tower, and generating steam to drive the turbine for power generation through the circulation of high temperature molten salt to heat water.
The trough type power station is similar to a large water tank, in the middle of the trough is arranged heat-conducting tube, the emitted sunlight shines on the heat-conducting tube to heat the heat-conducting oil, the heat-conducting oil will heat the water to produce steam to drive the turbine for power generation.
These are the two main power generation principles of domestic solar thermal power plants.

Reflector performance requirements
Good weather resistance to meet the test of harsh natural conditions, the smaller the reflectivity attenuation, the better. High energy reflectivity, high light gathering accuracy, low maintenance cost, low breakage and shattering rate, and low impact on power plant operation after damage.
Additional economic benefits of high energy reflectivity
Taking a 50MW trough-type solar thermal power plant as an example, for every 1% increase in the heat emission rate of the CSP reflector, the additional benefits that the plant can obtain during its 25-year life are calculated as
50MW x 1000 (converted to kW) x 5000h (annual power generation hours) x 25 years x 0.01 (1% efficiency improvement) x 1.15 RMB/kWh (feed-in tariff) = 71875000 RMB
The core component of the current commercial slot concentrator is the parabolic column reflector, which basically uses a 4mm ultra-white float silver-plated glass mirror. The processing of the reflector mirror is generally a high reflective film and multi-layer protective film on the back of the 4mm thick hot bent glass. Reflectivity and surface accuracy are important indicators of parabolic mirrors, and every 1% increase in reflectivity will significantly increase the power generation of solar thermal power plants, bringing considerable economic benefits over the life of the plant.
Weather resistance performance requirements for solar thermal mirrors
Weathering performance: (1) UV irradiation; (2) damp heat; (3) high and low temperature cycles; (4) wet freeze; (5) salt spray; (6) cleaning and maintenance.
With the increase of use time, the transmission rate of poorly weathered ultra-white glass will decay and the reflection rate will decrease, affecting the heat collection efficiency.
