First, TOPCon has significant technological advantages that drive its efficiency and costs down. At present, the average efficiency of P-type PERC cells is around 23.5%, while the average efficiency of TOPCon cells mass-produced by the head enterprise has reached more than 25.5%. DAS Solar’s CTO Song Dengyuan told the media that the empirical data applied in various environments show that TOPCon’s power generation is about 5%-7% higher than PERC’s. Next year, a large amount of new TOPCon capacity will enter the market, and the pace of dominant N-type capacity replacing P-type will accelerate, but there are still concerns about whether TOPCon can be a one-shot deal in the next few years. The first is the problem of falsely high module power. Different types of module products have different “standards” for power testing, and PERC technology and products have been in the market for a long enough time to have a unified standard, with less deviation in testing by different organizations. According to recent research data from the China Academy of Weights and Measures (CAWM), the power values measured by different third-party organizations for the same module vary from the actual power of the module —— in some products, the measured power value is nearly 14W higher than the actual power, which means that the buyer of the product will have to pay for the non-existent power of 14W. Second, the dispute between PECVD and LPCVD process route has no result. The new TOPCon puts forward new process requirements for the production preparation link, and most of the process adjustments can be achieved by slightly upgrading on the basis of the original PERC. However, the thin film deposition process, which is the core of the TOPCon battery technology, should be especially careful in the selection of process routes. Additionally, it is worth noting that free busbur is a cost reducing universal technology that can be used on TOPCon, HJT, and even on PERCs that are gradually fading out of the market. As Song Dengyuan said, “Photovoltaic technology is a wealth of humanity, and its core is the exploration and efficient use of solar energy for power generation.

TopCon Technology Explained: Why the 160W Next-Gen Panel Wins

Solar technology is evolving fast, and one of the most important breakthroughs in recent years is TOPCon (Tunnel Oxide Passivated Contact) cell technology. TOPCon panels deliver higher power output, better performance in low-light conditions, and improved long-term reliability. Another major advantage of TOPCon technology is its improved durability and lower long-term degradation. Because the cell design reduces stress on the silicon and minimizes power loss over time, TOPCon panels typically maintain higher output levels for more years compared to conventional panels. In traditional panels, some of the electricity created by sunlight is lost when electrons recombine before they can be used. TOPCon technology adds a very thin oxide layer and a special polysilicon layer that help guide electrons more efficiently, so more energy becomes usable power. When paired with a battery or a power station, it can also help run appliances for off-grid setups, RVs, boats, or emergency situations. TOPCon technology represents a major leap in solar efficiency, which offers higher power output, better low-light performance, and longer-lasting durability compared to traditional panels.

🌞 Introduction: Why You Should Know About TOPCon Solar Cells Solar energy is one of the best ways to produce clean electricity. But to get the most from your solar panels, you need the right kind of solar cells. One of the newest and most powerful types is called TOPCon solar cells. One of the biggest reasons people are excited about TOPCon technology is its high efficiency. TOPCon panels can reach 22% to 23.5% efficiency. Standard panels like polycrystalline reach only 15%–17%. Monocrystalline and PERC usually reach 18%–21%. That means with TOPCon, you get more power using the same space. Here are the top reasons why more people are choosing TOPCon technology: TOPCon cells are more efficient. You get more power per panel. Many TOPCon panels are bifacial, which means they generate electricity from both the front and the back side. That adds even more power! Even though TOPCon is amazing, it’s not perfect. ... Slightly Higher Price – Because of the advanced structure, TOPCon costs more than regular panels. Newer Technology – Not all installers are familiar with it yet.

Designed for energy yield improvement, these panels consistently outperform conventional technologies in real-world conditions. TOPCon modules typically achieve 23%-25% efficiency at the cell level, with some advanced models approaching 26% in controlled environments. This means they can produce more power from the same installation area, making them ideal for locations with limited roof or ground space. Businesses benefit from the durable and efficient nature of TOPCon technology. Whether powering factories, office complexes, or warehouses, industrial solar systems using TOPCon panels help reduce electricity bills and carbon footprints. Their superior temperature tolerance also ensures steady energy output in harsh environments. TOPCon technology also integrates well with energy storage systems, enabling hybrid solar solutions. Combining TOPCon solar panels with batteries allows for reliable, round-the-clock power supply, making them suitable for off-grid or grid-tied setups requiring energy independence and backup. The broad applicability of TOPCon solar technology across these segments underscores its position as a leading choice for sustainable and efficient solar power generation.

As we have seen in our previous article, there are several types of cell technologies battling on the market. Manufacturers are looking for new alternatives to reach higher efficiencies because the limits of PERC cells have been reached. TOPCON is one of the trending cell technologies getting more and more market share. TOPCon cells have a better power increase in bifacial modules than PERC modules. It is an important factor as bifacial solar modules are getting more and more popular on the market. TOPcon modules have a higher efficiency in low light condition, which extends the electricity generation period during the day and improve the performance of the installation over time. Figure 2 – World market share of PERC/PERL/PERT/TOPCon technology (Source: researchgate.net) The temperature coefficient is the percentage of power output lost by a solar panel for each degree of temperature increase. It impacts the power generation of PV modules in hot conditions. TOPCon cells have a better resistance to high temperatures, which means the efficiency of TOPCon modules will be higher in hot climates compared to PERC modules. To manufacture TOPCon cells, tunnel oxide, and polysilicon layers are added to the rear side of the cell. It helps the cell handle higher voltages, which increases power production.
