Newly Developed Cello Technology™

Cello Technology™:Improved Absorption of Light

LG has introduced newly developed ‘Cello Technology™ (Cell connection with Electrically Low loss, Low stress and Optical absorption enhancement)’ which increases power output and improves appearance.

Cello Technology™ improves the absorption of light with circular shaped wires, which scatter light more effectively.

Newly DevelopedCello Technology™

Technology

LG NeON™LG NeON™ 2

LG NeON™ 2 has 12 wires instead of 3 ribbons. In addition, distance between

wires has been shortened.

Cello Technology™ reduces electrical loss by increasing the number of electrical paths in the cell.

Cello Technology™: Less Power Generation Loss

Double-sided Cell Structure

The boron (B) and oxygen (O) pair within the p-type cell eliminates the electrons that were created to generate energy. But inside the LG NeON™ 2, there are almost no B-O pairs. This is why LG NeON™ 2 has almost no LID*.* LID: Light Induced Degradation

When micro crack or finger electrode erosion happens by natural degradation of mechanisms in the outskirts of the solar cell,LG NeON™ 2 reduces down performance by blocking the electrical path due to the tight layout of wires.

LG NeON™ 2 cell produces energy from both the front and back. By absorbing light from even the backside, the cells raise efficiency. This makes LG NeON™ 2 cells particularly more efficient than conventional cells in mornings and evenings when the incident angle is lower.

Compared with conventional multi module with 72 cells, LG NeON™ 2 achieves higher power output with 60 cells, making it easy to manage space when installing large scale systems. Also, with lower Voc than 72 Cell module, LG NeON™ 2 increases module quantity per ‘1 string’ that decreases the total number of strings which leads to lower cost.

LG NeON™ 2 reduces the space needed for installation due to its high module efficiency. The size and efficiency of the modules allow users to consider the shadow of physical objects such as trees or a chimney, to get the best possible outcome from a deployment.* Comparison of Module quantity and space when installing 4.8kWp on the roof

LG NeON™ 2 has an enhanced performance warranty. The annual degradation has fallen from -0.7%/yr to -0.6%/yr. LG has also extended the warranty of the LG NeON™ 2 for an additional 2 years.

* The comparison between the IRR (Internal Rate of Return) was calculated internally at LG to compare the relative return rate between different modules. Therefore, this return rate is not guaranteed. Further, the rate may differ according to the area and date of the analysis.
