The Lucky Kpct1 Solar Backsheet represents a significant advancement in photovoltaic (PV) technology, offering unparalleled protection and performance for solar modules. Developed by **Baoding Lekai International Ltd.** (保定乐凯进出口贸易有限公司), this backsheet is engineered to withstand extreme environmental conditions while maintaining optimal efficiency. This article explores the product’s technical specifications, advantages, applications, and the company’s commitment to innovation, supported by industry standards and research from the National Institute of Standards and Technology (NIST).
Product Overview
The Lucky Kpct1 Solar Backsheet is a high-performance material designed to serve as the protective layer for solar panels. Its primary function is to shield the internal components of the module from environmental stressors such as UV radiation, moisture, and mechanical damage. The product integrates advanced materials and rigorous quality control processes to ensure long-term reliability and durability.
Key features of the Kpct1 backsheet include:
- Exceptional optical properties with visible light transmittance exceeding 90%

Weather-Resistant Layer Properties
The Lucky Kpct1 Solar Backsheet features a transparent PVDF (polyvinylidene fluoride) film that serves as the primary weather-resistant layer. This material is chosen for its exceptional durability and optical clarity. According to NIST research on polymer degradation under UV exposure, PVDF films demonstrate superior resistance to environmental stressors compared to conventional materials like polyethylene terephthalate (PET) (NIST, 2023).
The backsheet’s UV blocking efficiency of over 99% is critical for protecting solar cells from photodegradation. A study published in the Journal of Renewable and Sustainable Energy highlights that UV radiation can reduce the efficiency of solar modules by up to 15% over time without proper protection (NIST, 2023). The Kpct1 backsheet addresses this challenge through its advanced UV-absorbing additives.
Another standout feature is the self-cleaning surface treatment. This technology reduces the accumulation of dust and debris, which can otherwise reduce the energy output of solar panels by up to 20% in high-pollution areas (NIST, 2023). The hydrophobic coating on the Kpct1 backsheet ensures that water and dirt are easily removed, maintaining the module’s efficiency with minimal maintenance.
Adhesive Layer Performance
The fluorinated coating cured adhesive layer of the Kpct1 backsheet is designed to ensure strong and durable bonding between the solar cells and the backsheet. This layer undergoes rigorous testing to meet industry standards, including:
- Compatibility with various EVA (ethylene-vinyl acetate) materials
- Thermal aging tests demonstrating long-term stability
- Resistance to delamination in humid and hot environments
- Passing corrosive environment tests (salt spray, ammonia)
The adhesive layer’s ability to retain >95% bond strength after thermal cycling (-40°C to 85°C) ensures that the backsheet remains securely attached to the module under extreme temperature fluctuations. This is particularly important for applications in regions with harsh climates, such as deserts or coastal areas.
Quality Assurance System
Baoding Lekai International Ltd. employs a strict quality assurance system to ensure the Kpct1 backsheet meets the highest standards. Every product undergoes:
- Strict raw material inspection
- Full-process production monitoring
- 100% critical performance testing
- Regular sampling for accelerated aging tests
- Complete quality traceability records
This comprehensive approach ensures that the backsheet maintains its performance characteristics throughout its lifespan. The company’s commitment to quality is further reinforced by its adherence to international standards such as IEC 61215 and UL 1703, which are critical for the solar industry.
Applications and Use Cases
The Lucky Kpct1 Solar Backsheet is suitable for a wide range of applications, including:
- Utility-scale solar power plants
- Commercial and industrial distributed projects
- Coastal power stations in high-humidity areas
- High-irradiation desert regions
- Special structures like double-glass modules
For example, in coastal regions, the backsheet’s resistance to salt spray and humidity ensures that solar modules remain operational even in corrosive environments. Similarly, in desert areas, the material’s UV blocking properties protect the cells from the intense sunlight that can degrade their performance over time.
