TOPCon: The Future Leader in Photovoltaic Technology
Trina Solar is betting on TOPCon(Tunnel Oxide Passivated Contact) technology in the photovoltaic sector. These modules can produce up to 3.4% more electricity per month, compared to rear-contact BC modules. A later field consideration conducted by the company shows that TOPCon modules offer higher control generation by a normal of 3.15% per watt compared to back contact (BC) modules, with a relative pick up of up to 3.4% in one month. This analysis demonstrates the superior power generation of TOPCon modules and the added value they will bring to customers in the years to come.
TopCon Modules
The test was conducted from July 16 to September 10, 2024, in Changzhou, China. Trina Solar compared the performance of Vertex N 600W bifacial dual-glass modules, based on the advanced n-type technology, i- TOPCon, with 620W tunnel back contact (TBC) bifacial dual-glass modules from another manufacturer.
Testing Setup: Conditions and Parameters Explained
To ensure accuracy, the test site was designed to closely recreate normal installation conditions. It included a concrete floor with a reflectivity of around 30%, with the modules mounted on fixed mounting frames at a tilt angle of 23° and installed 0.5 meters over the ground. There was no shading on the front or raised rows, and power generation information was collected using an IV tracker.
TOPCon Modules Perform Better in Low Light
TOPCon modules demonstrated superior performance under low irradiance conditions, such as in the morning and late evening hours. From 7 a.m. to 8 p.m., the power output per watt of TOPCon modules was 6.9% higher than that of TBC modules, and from 5 p.m. to 7 p.m., their relative pick-up was 8.3% to 8.4%. This is reliable with past field tests showing TOPCon beats BC by around 5% under low irradiance conditions.
TOPCon’s Bifaciality Boosts Overall Power Generation
TOPCon ’s higher bifaciality also contributes to its higher power generation: indeed in the early afternoon, when sunlight is strong, TOPCon modules offer a 2.6% advantage in control generation over BC options. The combination of high facility and tall execution at low irradiance enables TOPCon modules to provide a control generation pick-up of 2% to 3% per watt compared to BC modules under real-world working conditions.
China’s Testing Confirms TOPCon as Future PV Leader
These findings are reliable with results from the National Photovoltaic and Energy Storage Test Stage and the National Solar Photovoltaic Product Quality Review Center, both based in China. The test results provide strong proof that TOPCon will be the overwhelming PV innovation in the another five long time, with advanced efficiency changes and cost decreases still to come. Trina Solar expects that cell efficiency will increase by an extra 1% in this time.
TOPCon Modules: Leading the Way in Solar Advancements
The control of TOPCon modules will develop by more than 30 W in the same period. In five years, the company expects TOPCon-based n-type perovskite-silicon pair solar cells to end up being the benchmark for high-quality improvement in the photovoltaic industry. The solar photovoltaic industry is booming and innovations in the sector are the order of the day. TopCon modules are a good example of this.
