Advantages and Cell Efficiency of Longi HPBC Solar Cells
The core advantage of LONGi Green Energy's HPBC (Hybrid Passivated Back Contact) technology, particularly in its second-generation (HPBC 2.0) products, lies not only in high laboratory efficiency but more importantly in its ability to deliver higher and more stable real-world power generation value throughout the entire lifecycle of a photovoltaic system.
The table below summarizes the main advantages of this technology:
| Advantage Category | Specific Performance |
|---|---|
| Technical Core & Efficiency | No front-side busbars, refined backside design. Mass-produced module efficiency reaches 24.8%. HIBC modules based on this platform achieve even higher efficiency, up to 25.9%. |
| ✨ High Power Generation Yield | Power generation per unit area is over 10% higher than conventional TOPCon modules. Relative efficiency gain of 1.9% under low-light conditions (200W/m²). |
| ⚡ Excellent Reliability ("Triple Protection") | Anti-dust accumulation: Frame design enables self-cleaning with rainwater, providing an average power gain of 2.04%. Anti-shading: Current can bypass obstacles, reducing power loss by 70% compared to TOPCon. Anti-fire/hotspot: Temperature at shaded spots is about 50°C lower than TOPCon. |
| Platform-based Scalability | Serves as a foundational platform for integration with future technologies (e.g., perovskite), paving the way to the tandem cell era. Has spawned scenario-specific products like lightweight and anti-glare versions. |
HPBC technology is a platform-based back-contact cell technology. Its core structure involves moving all electrode busbars to the back of the cell, resulting in a front side completely free of busbar shading, thus achieving 100% light-receiving area.
Cell Efficiency: Currently, mass-produced modules using HPBC 2.0 technology can achieve a maximum conversion efficiency of 24.8%. Building on this platform, LONGi has also launched even higher-efficiency HIBC modules, with mass production efficiency reaching 25.9% and power exceeding 700W. According to the company's senior management, modules based on HPBC 2.0 represent the last product to achieve a more than 1% efficiency improvement for crystalline silicon cell modules. The next leap in efficiency will depend on perovskite tandem technology.
Technological Positioning: LONGi believes BC technology (Back Contact, the broader category including HPBC) is currently the technology closest to the theoretical efficiency limit of single-junction crystalline silicon cells, offering significant advantages over mainstream TOPCon and HJT technologies. It already has the capability to push laboratory cell efficiency to 27.0%.

The advantages of HPBC technology are specifically reflected in actual power generation and system safety:
Delivers Higher Actual Power Generation: High conversion efficiency means higher-power modules can be installed on the same roof or land area, directly increasing total power output. Empirical data shows its power generation per unit area can be over 10% higher than conventional TOPCon modules. Furthermore, the technology features excellent low-light response, maintaining good performance during low-light conditions like early morning, evening, or cloudy weather, effectively extending daily power generation hours.
"Triple Protection" Ensures System Safety & Stability: This is a key innovation of HPBC technology addressing pain points in distributed PV applications:
Anti-dust Accumulation: A special frame design allows modules to utilize rainwater for self-cleaning, reducing dust buildup. This not only lowers maintenance costs but also provides an average power gain of 2.04%.
Anti-shading: When part of a module is shaded, its unique circuit design allows current to "detour," preventing a sharp power drop in the entire cell string. It reduces power loss by 70% compared to TOPCon products.
Anti-fire (Anti-hotspot): This anti-shading capability significantly reduces the risk of high-temperature "hotspots" caused by shading. Tests show that under the same shading conditions, HPBC module hotspot temperatures are about 50°C lower than those of TOPCon modules, greatly enhancing the fire safety of power plants.
Strong Platform Scalability: HPBC is not just an independent cell technology but an open technology platform. Its front-side electrode-free structure provides a natural advantage for integration with next-generation perovskite tandem technology, seen as an inevitable path toward even higher efficiencies. Currently, LONGi has developed differentiated products based on this platform for various scenarios, such as lightweight modules for roofs with low load-bearing capacity and anti-glare modules suitable for light-sensitive areas like airports and highways.
When selecting products, you can focus on different product series based on the application scenario: For standard commercial and industrial rooftops, the Hi-MO X10 series with "Triple Protection" features is the primary choice; for older factory buildings with limited load-bearing capacity, the Hi-MO X10 lightweight module should be considered; for large-scale ground-mounted power plants, the highly efficient bifacial Hi-MO 9 series can be considered.
In summary, the core value of LONGi's HPBC technology lies in shifting the focus of PV competition from pure "efficiency numbers" to "power generation value" and "safety & reliability" over the entire power plant lifecycle. Whether pursuing higher investment returns or needing to handle complex installation environments, it offers a highly competitive solution.
If you have more specific questions about particular application scenarios (like residential rooftops or large power plants), I can provide more detailed analysis for you.
