ALSOLAR®

Outline

This is an ink for forming the rear electrode aluminium on crystalline silicon solar cells. Its main ingredients are aluminium powder, organic binders and solvent. When ALSOLAR® is coated onto silicon wafers then dried and fired, it is not only effective as the rear electrode, it is also possible to form a high quality and uniform BSF layer. It is therefore an essential product for the manufacturing of high quality solar cells.

Characteristics of fired cells using ALSOLAR®

It is possible to manufacture cells that have excellent resistance to weather.
Adjustments can be made for customers to suit the environment of use and improvements can be made to meet requirements.
