Many people are curious to know what is a ToPCon solar cell? TOPCon is an exciting new advancement in the solar power industry. First proposed in 2014 by Fraunhofer ISE, this N-type silicon cell technology was scaled five years later and is now being used by some of the biggest names in the business. Suntech, Trina Solar, JA Solar, and LONGi Solar are all utilizing TOPCon to bring efficient models that outperform even their high standards.
January 2022 will mark a monumental point in history due to TOPCon’s ability to reach impressive efficacy levels above 22%. These findings could potentially be a game changer when it comes to global renewable energy production; as more and more leading companies turn towards this advanced technology, we can look forward to a future with cutting-edge solar power panel capabilities.
TOPCON, which is also called a passivated contact, is a solar cell technology that has been hailed as the future generation of energy-efficient cells in Germany, 2013 by the researchers Fraunhofer Institute for Solar Energy Systems.
Unlike some of the other possible novel technologies like IBC & HJT, TOPCON can be realized with line upgrades from the existing PERT or PERC production lines, resulting in considerable savings in capital investment costs. Furthermore, excellent gains in efficiency are also achievable – reported improvements range from 1 percent in absolute value according to recent studies.
TOPCON is an acronym for “Tunnel Oxide Passivated Contact”, and if future developments prove successful, it could be a cornerstone of the industry’s progress going forward.
A few modifications are necessary to transform an n-PERT solar cell into an n-TOPCON solar cell. Specifically, adding an ultra-thin SiO2 layer and a doped poly-Si layer is sufficient.
The ultra-thin SiO2 layer acts as a surface passivation layer, separating the rear Si surface and the poly-Si layer, which functions as the rear contact. For the current to tunnel through it quantum mechanically, the SiO2 layer must be thin enough.
The heavily doped poly-Si layer generates a highly conductive layer that functions as a contact for the current collection. In an n-type TOPCON, the poly-Si layer is infused with a touch of phosphorus to offer the perfect blend of back surface field & field passivation. The Fraunhofer Institute for Solar Energy Systems observed a 1% increase in the absolute efficiency of solar cells by adding a tunnel oxide layer.
When you choose TOPCON solar cells, you’re not just investing in renewable energy – you’re investing in a brighter, cleaner, and more sustainable future for all.
In conclusion, the TOPCON solar cell is an exciting new addition to the renewable energy landscape. With its impressive characteristics and features, it could play a huge role in helping us make strides toward meeting our climate goals. Plus, this powerful technology is becoming more accessible every day thanks to increased availability on the market and the willingness of communities around the world to invest in sustainable energy sources.
