Solar photovoltaic pvb film
A new application to photovoltaic
The advantages of using an integrated photovoltaic system in architecture are daily enhanced in the advance countries. Under global energy cost is raising, in order to evaluate the potential prospect of the photovoltaic architectural integrated system,architects and engineers are working together on a new integrated solution in glass wall and roof. The solar cell module is a special laminated glass (sealed crystal silicon panel).the new developed integrated photovoltaic architectural system with characteristic of protection and safety will be more attractive to architects and also incrase more chances to solar cell module producers in architecture and glass industry
Daruihengte is the leading PVB film supplier in the field of architectural and automotive.As knowing well the importance of solar cell energy market,the company is the earliest supplier in developing special photovoltaic film. The solar cell module appears high transparency, high adhesive, excellent thermal, UV protection, moisture resistant.it is High reliability when it is kept even exposed to the terrible outdoor conditions for long time.
The photovolmaic PVB film can enhance the anchoring strength of the solar cell commponents after the film is laminated,cross-linked and solidified with the glass. For more the PVB film can also provide the solar cell with a good mechanical,thermodynamic and optical protection,which can also extend the lifetime of solar cell module with a cost saving purpose.
