CETC Solar Energy, green power unlimited

Solar Cell

High performance solar cells - the decisive factor for top quality solar modules.

At a very early stage CETC Solar Energy addressed the question of how they could optimise its Solar Modules. The answer: by ensuring the constant, uniform efficiency of all the incorporated cells. This has been duly achieved in the form of our multicrystalline and monocrystalline solar cells that are available in a variety of formats and output classes and are manufactured in our production facilities equipped with the world's latest solar cell manufacturing systems.

Recently, CETC Solar Energy has also improved the current state-of-the-art by integrating a high-efficiency rear surface design - the PERC (passivated emitter rear cell) structure. The PERC structure offers a 1% efficiency boost and has steadily gained traction in recent years and is compatible with common screen printing techniques. Its variations include bifacial P-type PERC solar cells. The PERC design currently accounts for only 10% of worldwide crystalline silicon solar cell production but is expected to be the dominant cell architecture by 2024, projected to reach a market share of 45%.

Features

  • Outstanding surface quality.
  • Advanced diffusion technique ensuring the homogeneity of energy conversion efficiency of the cell.
  • Advanced PECVD film forming, providing a dark blue silicon nitride anti-reflection film of homogenous color and attractive appearance.
  • High quality metal paste for back surface and electrode, ensuring good conductivity, high pulling strength and ease of soldering.
  • Efficiency-increasing 3-busbar, 4-busbar and 5-busbar technology that optimises electricity collection and ensures optimal electricity yield from your system.
  • First-rate efficiencies and superlative output consistency.
  • Excellent anti-PID performance (under the following conditions: 60°C, 85% humidity, -1000V, 96 hours).
  • Lower power loss through encapsulation. Appropriate electrical performance parameters (high voltage and low voltage). Current evaluation and positive tolerance for the cell performance compensation guarantee a very low loss from cells to modules.
  • Outstanding solderability. Application of double-printing technology in production improves solderability.
  • Meticulous tolerance and quality checks guarantee a constantly high solar cell output capability and the resultant excellent quality of CETC Solar Energy Modules.
