Bifacial photovoltaic glass, as the name suggests, are photovoltaic modules that can absorb sunlight on both the front and back sides and convert it into electrical energy. This type of component is encapsulated with two pieces of glass, and compared with the traditional single-sided photovoltaic panel, it has a significant improvement in the utilization rate of light energy. The design of bifacial and double-glass photovoltaic modules not only enhances the stability of the structure but also reduces long-term operation and maintenance costs due to their better weather resistance and anti-aging performance.
1. Performance characteristics
A. High light transmittance: The back glass should allow sufficient light to pass through to ensure that the battery on the back generates electricity.
B. Mechanical strength: Tempering treatment and weather resistance.
C. PID resistance: Prevent potential induction attenuation through special coating or material processes.
D. Lightweighting trend: Thin glass (such as 1.6mm to 2.5mm) is adopted to reduce weight.
2. Manufacturing process
A. Original sheet selection: ultra-clear glass original sheet.
B. Coating process:
a. Front: Anti-reflective coating.
b. Back: Anti-reflection or scattering coating (to enhance the utilization rate of diffuse reflection light).
c. Tempering treatment: Thermal strengthening or chemical tempering to ensure impact resistance and bending strength.
d. Edge treatment: Chamfering or sealing (to prevent edge stress cracking).
