How to improve visible light transmittance of Photovoltaic Glass?

To improve the visible light transmittance of photovoltaic glass, there are currently two directions. One is to apply an anti-reflection coating on the surface of the photovoltaic glass to improve the light transmittance of the photovoltaic glass, and the second is to use a self-cleaning anti-reflection film.

What standards are included in a photovoltaic system?

In addition to referencing international electro-technical photovoltaic standards such as IEC 61215, IEC 61646 and IEC 61730, typical standards from the building sector are also included, such as: EN 13501 (Safety in case of fire); EN 13022 (Safety and accessibility in use); EN 12758 (Protec-tion against noise).

What is laminated Solar Photovoltaic Glass?

Laminated solar photovoltaic glass is defined as laminated glass that integrates the function of photovoltaic power generation. ISO 12543 (Glass in building — Laminated glass and laminated safety glass) is referenced for many of the requirements other than electrical properties.
