Jolywood’s material exhibits included a black mesh backsheet, a reflective black backsheet, and an EPE encapsulant
Among the module products, the company showcased a lightweight, flexible module suitable for several off-beat applications
Its latest Windproof module series features a low-carbon double-beam steel frame with mechanical strength comparable to aluminum, a low carbon footprint, and lower cost
Jolywood, a market leader in the backsheet segment, an encapsulation materials supplier, and a PV cell and module producer, is one of the early adopters of n-type technology.
At this year’s Intersolar Europe exhibition in Munich, Germany, Jolywood’s booth showcased its latest PV materials alongside a wide array of PV modules incorporating these materials. During a visit to the booth, the TaiyangNews team was given a brief tour of the company's product lineup by Vincent Wang, R&D Director at Jolywood. He also shared insights into the company’s future strategy for staying competitive in today’s challenging global PV market landscape.
The first product highlighted was the company’s latest reinforced frontsheet, which has been incorporated into the company’s new NIWA Air series of flexible PV modules. This product has a rated power of 575 W and an efficiency of 20.9%; however, the interesting part is its applications. The company promotes this flexible module for specialty applications such as curved roofs, camping, balcony solar, and vehicle roofs.
Wang then quickly walked through the exhibits from Jolywood’s mainstream PV module materials. These include its latest transparent backsheet with black grid. Featuring a PET polymer core with FFC nano-coating on both sides, this product attains a light transmission rate of over 93%, according to Wang. He added that the product’s performance has been validated through multiple outdoor field tests, showing less than 2% degradation after 3 years of service.
A reflective black backsheet was next. The backsheet, which is black in color on the cell side, gives the module an all-black appearance while reflecting the sunlight to improve optical absorption at the same time.
The company's EPE encapsulant was a major highlight among its full spectrum of encapsulation solutions.
Maintaining mechanical strength amid changes in module layout, particularly along the long side, is a challenge. Jolywood has introduced a module featuring a steel frame that replaces the traditional aluminum frame to address this challenge. According to Wang, its double-beam steel frame design offers mechanical strength comparable to that of conventional aluminum frames while reducing carbon emissions by up to 45% and lowering costs. For long-term reliability, the steel frame is coated with a 25 µm layer of Aluminum-Magnesium-Zinc. The module has a rated power of 645 W and an efficiency of 23.9%.
Additionally, the company offers a thin-glass encapsulation solution that combines 1.8 mm-thick tempered glass with a transparent meshed backsheet and a double-beam steel frame. This design ensures mechanical durability under extreme environmental loads, such as heavy wind and snow. In addition, the breathable nature of the underlying backsheet helps expel acids that may form within the module lamination, thereby reducing the risk of busbar metallization corrosion, says Wang. Wang claims this module is 17-20% lighter than a standard double-glass module, which helps reduce transportation costs and improves installation efficiency.
