Description

Introduction

One promising technology for improving solar cell efficiency is Tunnel Oxide Passivated Contacts (TOPCON). Those high efficiency solar cells address the challenge of passivation contact by utilizing N-type silicon wafers.

Light intensity reliability

Features

TOPCON technology offers several advantages over traditional solar cells:

• High conversion efficiency:

TOPCON can significantly boost the efficiency of N-type solar cells, reaching up to 24.5%. This translates to a 210mm TOPCON cell generating a rated power of 10.76 watts, a notable improvement over previous technologies.

• High reliability and durability:

TOPCON cells exhibit high reliability due to their resistance to light-induced degradation, a common issue with some solar cells. Additionally, tight process controls ensure uniform cell performance across production batches.

• Strong low-light performance:

Even in low-light conditions, TOPCON cells deliver excellent power generation, making them suitable for a wider range of environments.

• Low hot spot risk:

TOPCON cells are less prone to hot spots, which can damage solar panels in certain conditions.

Applications

Due to their impressive efficiency and durability, TOPCON solar cells are ideal for various applications, including:

• Rooftop solar panels:

TOPCON’s high efficiency can maximize power generation in residential and commercial rooftop solar installations.

• Utility-scale solar farms:

Large-scale solar farms benefit from TOPCON’s ability to generate more electricity from the same amount of sunlight.

• Building integrated photovoltaics (BIPV):

TOPCON cells integrate into building materials, enabling the direct generation of solar power on rooftops or facades.

210mm TOPCON High Efficiency Solar Cells

The 210mm TOPCON solar cell is a larger format cell that  leverages the efficiency benefits of TOPCON technology. The increased size enables the use of fewer cells per panel,  potentially simplifying manufacturing and reducing interconnection losses. Because the panels are rated at 10.76 watts,  they can form more powerful solar panels. In conclusion, TOPCON technology represents a significant advancement in solar cell design.
