Core technology breakthrough: Architecture Innovation and Performance Reshaping
Traditional solar cells are limited by the design of the front grid lines, resulting in optical losses of 5-8% and parasitic resistance effects. The all back contact cell has achieved a revolutionary reconstruction of the carrier transport path through a three-dimensional stacked back-contact architecture, completely solving the problem of front surface recombination loss.
The all-domain light absorption interface:
By adopting a nanoscale velvety light-trapping structure and spectral conversion coating, the effective photon capture rate is increased to 98.5%, and the quantum efficiency remains above 90% within the 300-1180nm wavelength range-further enhancing the energy conversion advantages of the all back contact cell.
Quantum tunneling conduction mechanism:
By constructing a titanium nitride/molybdenum oxide composite electrode system through atomic layer deposition technology, the contact resistance is reduced to 0.15mΩ·cm², and the power output curve maintains superlinear characteristics within the range of 0.1 to 1.5 standard solar intensities.
Breakthrough in micro-light power generation performance:
It still maintains a peak power output of 78% at an irradiance of 50W/m², and the effective power generation time during day and night is 2.8 hours longer than that of conventional PERC cells.
Full life cycle reliability engineering
We adopt aerospace-grade reliability design standards and have established a comprehensive guarantee system covering everything from the intrinsic properties of materials to system integration.
Intelligent thermal management system:
Equipped with a distributed micro thermoelectric cooling module, it can keep the battery operating temperature within 45°C even at an ambient temperature of 60°C, with the temperature coefficient optimized to -0.25%/°C.

Marine-grade protective system:
The carbon-based protective layer of diamond-like carbon prepared by plasma enhanced chemical vapor deposition technology has been certified to maintain performance degradation of less than 3% for 25 years in an alternating acid-base environment with pH4-11.
02
Mechanical stress adaptive structure:
It adopts a bionic spider web support framework, with wind pressure resistance increased to 8000Pa and hail impact resistance passing the 35m/s impact test of a 45mm ice ball.
03
Digital life prediction platform:
Implanted with 5G iot chips, it can monitor over 200 performance parameters in real time. Based on digital twin technology, it achieves a remaining life prediction accuracy of over 95% and provides a 35-year output power guarantee.
