In the past few years, Solardeland has launched the N-topcon series of products, driven by the increasing demand for renewable energy and the advancement of photovoltaic (PV) technology, while the solar industry has experienced unprecedented growth and innovation. In this dynamic landscape, N-type tunnel oxide passivated contact (N-TopCon) solar technology has become a leader due to its superior efficiency, durability and cost-effectiveness. The rise of N-TopCon is a breakthrough that solves several technical limitations of traditional PERC (Passivated Emitter Rear Cell) technology. However, as the industry has evolved, other high-efficiency alternatives have emerged, such as heterojunction (HJT) and back contact (BC) technologies, each of which has unique capabilities and potential advantages.
Solardeland started with the advantages of N-TopCon technology and investigated whether the newer HJT and BC technologies have the potential to surpass N-TopCon. To understand this, it is necessary to evaluate the advantages of each technology in terms of efficiency, manufacturing complexity, cost and scalability. The goal is to clarify N-TopCon’s place in today’s solar market and its long-term prospects in the face of competition from HJT and BC.
Explain the evolution of N-TopCon, which emerged to address the limitations of traditional PERC technology, including efficiency droop and temperature sensitivity.
Briefly describe the working principle of N-TopCon cells, focusing on the tunnel oxide layer that enhances electron flow and reduces recombination losses.
Detail how N-TopCon’s efficiency exceeds PERC by 1-2% due to lower droop and higher bifacial gain, while production costs remain competitive.
Highlight N-TopCon’s long-term stability, providing better long-term performance in large-scale installations.
N-TopCon typically achieves efficiency levels of 24–25%, approaching the performance of HJT and BC, but with lower manufacturing costs.
Describe the simpler production process of N-TopCon, which can often be retrofitted to PERC production lines, reducing the need for a large number of new equipment.
Discuss how N-TopCon provides better temperature stability and lower light-induced degradation (LID), making it reliable in different climate conditions.
Solardeland mainly launches 590W-730W series products, which support customized services and can basically meet all customers' photovoltaic needs.
Explain the structure of HJT, which combines crystalline silicon with thin film layers to achieve extremely high efficiency (up to 26%) and excellent temperature coefficient.
Analyze the high cost and manufacturing challenges faced by HJT, especially the need for advanced materials and specialized processes that hinder its scalability.
Describe the BC architecture, which places all contacts on the back of the cell to increase front light absorption, thereby improving efficiency.
Note the challenges faced by BC, such as increased production complexity and sensitivity to shadowing, which may affect the performance of some installations.
Compare the efficiency level of N-TopCon (24–25%) to HJT and BC cells, noting that while HJT can achieve higher efficiencies, the difference is small and may not justify the cost in many markets.
After in-depth market research, Solardeland found that HJT technology is slightly better than N-topcon technology in terms of efficiency, but N-topcon technology is higher than HJT technology in terms of price.
Discuss how N-TopCon is more scalable due to compatibility with existing PERC production lines, while HJT and BC require large capital investments.
Market Adoption and Demand: Emphasize how the current market demand for efficient, cost-effective solutions favors N-TopCon, especially for large utility projects.
Solardeland analyzed the maturity of N-TopCon compared to HJT and BC and found that N-TopCon has reached a more stable production stage, while HJT and BC are still in the development stage for large-scale implementation.
Understand the future cost reduction trends of HJT and BC and how they affect their market feasibility.
In the end, it is believed that although HJT and BC have slightly higher efficiency, N-TopCon's balance of cost, scalability and performance ensures its relevance and resilience in the short term.
N-TopCon technology has achieved significant growth, proving its capabilities as an efficient and cost-effective solar solution. Although HJT and BC technologies offer impressive performance in niche areas, they face challenges in scalability and production costs, which may limit their mainstream applications. N-TopCon combines advanced performance with lower production costs, making it the dominant technology in the industry for the foreseeable future. However, as HJT and BC develop, the industry will need to pay attention to any breakthroughs that may change the competitive landscape.
