NO PID & NO LID DUE TO HETEROJUNCTION TECHNOLOGY

HETEROJUNCTION CELL NUCLEUS STRUCTURE

Heterojunction technology is based on an N-doped crystalline silicon wafer, which is coated with very thin amorphous crystalline layers. This cell structure is responsible for the efficiency advantage over conventional cell technologies.

Photovoltaic cells differ in their layer structure in negatively charged N-type cells and positively charged P-type cells.
If the base-layer is doped with boron, it is a P-type cell. This has one electron less than silicon. This creates an electron hole and the positive charge carriers predominate. With N-type cells, the base layer is doped with phosphorus. This has one more electron than silicon, which creates free electrons.

These free electrons enable the higher efficiency of the N-type cells.
They are responsible for the extremely low power losses and prevent phenomena such as PID and LID.

BETTER TEMPERATURE BEHAVIOR

BETTER TEMPERATURE BEHAVIOR

HIGHER EFFICIENCY

Heterojunction cells combines the advantages of two technologies. The crystalline N-Type based cell core allows more direct sunlight to be converted into electricity.

The amorphous cell layers also ensure better weak light behavior and significantly higher resistance to high temperatures.

The temperature coefficient describes the performance of the modules at fluctuating temperatures. As the temperature rises, the power drops.

 

HIGHER BIFACIALITY = HIGHER YIELD

Heterojunction cell achieves optimal bifaciality thanks to its symmetrical structure. Indirect light is absorbed by the solar cell on both sides.

The bifaciality factor of heterojunction solar modules is up to 95%.
