Trina Solar Launches N-Type i-TOPCon Advanced Technology with 26% Production Efficiency

28 Aug 2023

On 8 June 2023, Trina Solar, a Chinese photovoltaics company, made a significant announcement by introducing its latest N-Type i-TOPCon advanced technology. It was unveiled for the first time at the International Solar Photovoltaic Power Generation and Smart Energy Conference and Exhibition in Shanghai on 24 May 2023.

With the growing demand for solar cells with the upper level of efficiency and flexible manufacturing process with TOPCon technology, the solar cells market is witnessing exceptional demand. 

According to data insights from BIS Research, the global TOPCon solar cells market was valued at $7.54 billion in 2022 and is anticipated to reach $40.69 billion by 2032, witnessing a CAGR of 19.8% during the forecast period 2023-2032.

Here’s the Story 
At the latest N-Type i-TOPCon advanced technology launch, Dr. Chen Yifeng, Associate Vice President of Trina Solar, highlighted the importance of four key innovations that underpin the N-Type i-TOPCon advanced technology, which includes:
•    210R rectangular cell
•    selective boron emitter
•    backside microstructure reflector
•    highly doped TOPCon structure with Plasma-enhanced chemical vapor deposition (PECVD)

These advancements have enabled the new-generation i-TOPCon advanced technology to achieve an impressive production efficiency of up to 26%, with module power output reaching 700W.

Research suggests that TOPCon solar cells have the potential to reach maximum efficiencies ranging from 28.2% to 28.7%, surpassing the 24.5% efficiency of Passivated Emitter and Rear Contact (PERC) solar cells. This higher efficiency leads to increased energy harvesting per unit area.

According to BIS Research, the N-type segment is expected to lead the TOPCon solar cells market in the forecast period 2023-2032, owing to growing demand from end-use industries such as commercial and residential and its higher efficiency and improved passivation. 

In recent times, there have been notable improvements in the electrical output, thermal coefficient, and absorption speed of N-type solar products. Ongoing research suggests that N-type products offer increased reliability and the ability to generate power at a higher rate, approximately 3% more than P-type products.

The introduction of the Vertex N modules with power capacities exceeding 700W holds significant implications for utility power plants. These high-performance modules contribute to a reduction in the levelized cost of electricity (LCOE) for solar installations. Moreover, these modules also bring the promise of mass production in the coming year, 2024. 

During the exhibition, Trina Solar shared updates on its ongoing projects. For instance, Phase II of the company's 15GW monocrystalline silicon ingot project, located in Xining, Qinghai province, has commenced. 

Moreover, work has begun on the 10GW N-Type high-efficiency cell and 10GW N-Type module project in Yangzhou, Jiangsu province. These initiatives demonstrate Trina Solar's commitment to expanding its production capacity and advancing the development of innovative solar technologies.

Trina Solar revealed that starting in 2024, the Vertex N-Type series will undergo an upgrade, with the most powerful module in the series generating over 700W of power.

Trina Solar also demonstrated its leadership in establishing a net-zero system by initiating the Environmental Product Declaration and carbon footprint certification for its Vertex N-Modules. This initiative showcases the company's dedication to promoting its sustainable practices and reducing environmental impact within the solar industry.

The TOPCon solar cells market is witnessing growth as organizations seek alternative solar cell technologies that offer lower manufacturing costs, simplified operations, and improved effectiveness.

Moreover, providers in the TOPCon solar cells market are focusing on developing more efficient and durable cells to meet changing industry demands. While the market is currently consolidated, established providers may face competition from emerging companies working on advanced and highly efficient TOPCon solar cells.
