US Solar Future in Focus at RE+ 2025

TaiyangNews will explore the US solar market amid evolving regulations at the upcoming RE+ 2025 event in Las Vegas. We are co-organizing the 2025 Solar Made in USA Summit in collaboration with RE+ and EUPD Research. Scheduled for September 8, 2025, this physical event will bring together leading solar industry experts to discuss the future of US solar and storage manufacturing, as well as strategies for navigating regulatory challenges posed by the OBBBA. Registrations are now open here.

Local Advantage Key to Success

Panel Discussion

TaiyangNews’ Head of Technology, Shravan Chunduri, asked the panelists for their advice on setting up solar cell production lines outside China. Among the key messages from DKEM’s Director of New Technology Development, Fangqing Guo; Leadmicro's CTO, Dr. Jerry Liao; and RCT Solutions Sales Director, Sukumar Madugula, was an emphasis on cost management, strong engineering, and skilled teams. Leveraging local sourcing offers an edge, while stressing the importance of friendly local policies and reliable supply chains for smooth operations. 

India’s Solar Expansion in Focus

With proper local strategies and engineering, CapEx and timelines for module lines can improve as per RCT's Sukumar Madugula

Sukumar Madugula, Sales Director at RCT Solutions, highlighted India’s rush to set up solar cell lines amid 100+ GW installed capacity, >45 GW annual demand, and DCR requirements. He questioned the focus on branding modules, suggesting that the market can consider cell-only lines or partnerships instead. With proper local strategies and engineering, CapEx and timelines for module lines can improve. Madugula believes module line investments remain viable with the right approach.

Protecting Cells from UV-ID

Cybrid Technologies’ Raybo encapsulant film is designed to address UV-induced degradation in TOPCon cells.

Cybrid Technologies’ Raybo encapsulant film is designed to address UV-induced degradation in TOPCon cells. The film significantly reduces UVID while keeping the cell’s UV sensitivity intact, resulting in a power boost of about 1%, said Deputy CTO Dr. Hisanari Onouchi of Cybrid. The company also offers EPE encapsulant, which he said ensures excellent lamination and anti-PID performance for double-glass modules, enhancing reliability for long-term use.

Lower Cost, Higher Output For TOPCon

Chun Zhang, CTO of CETC Red Solar, detailed the company’s TOPCon equipment portfolio, including ALD and PECVD coating solutions.

Chun Zhang, CTO of CETC Red Solar, detailed the company’s TOPCon equipment portfolio, including ALD and PECVD coating solutions. He claims that the company's patented stacked graphite boat PECVD system increases throughput by 15%, achieving up to 500 MW, while reducing total cost of ownership by 10% and improving material utilization.

40% Throughput Gain For LPCVD

Dr. Jerry Liao, CTO at Leadmicro, discussed the development of the company’s latest LPCVD tool designed for back contact technology

Dr. Jerry Liao, CTO at Leadmicro, discussed the development of the company’s latest LPCVD tool designed for back contact technology. The new tool delivers 40% higher throughput of 8000 pieces per tube, achieved through innovations such as an updated double-paddle design and an improved furnace hot zone, which ensures better film uniformity with just 3% deviation, he claimed.

DKEM Pushes Copper Forward In Solar Cells

Fangqing Guo, Director of New Technology Development at DKEM, speaks at TaiyangNews Conference

Copper continues to dominate discussions as the leading alternative to silver in solar cells, thanks to its lower cost and good conductivity. The challenge? Oxidation and the sensitivity of its firing process to the atmosphere, along with concerns about module reliability. Fangqing Guo, Director of New Technology Development at DKEM, revealed the company's solution: an ultra-low silver seed layer followed by high copper paste. This approach is already in mass production, and both cells and modules have passed reliability tests.

PECVD Powers TOPCon Leadership:

TOPCon cell technology is set to lead the solar PV market for the next 10 years as per Shenzhen S.C New Energy's Homer Chen

TOPCon cell technology is set to lead the solar PV market for the next 10 years, says Homer Chen, Associate Dean of Research Institute at Shenzhen S.C New Energy. Highlighting PECVD’s lower cost of ownership among other benefits compared to LPCVD, he claims that his company is the sole supplier of PECVD tools to major manufacturers with multi-GW capacities, and that its equipment enables 25.5% TOPCon cell efficiency and over 98% yield in mass production.

TOPCon Leads Over Back Contact

Demand for TOPCon and TOPCon+ is higher

Back contact technology is more challenging to master and requires 120% more manpower compared to TOPCon, notes Dr. Josua Stückelberger, Director of Technology – International Business Unit at LAPLACE. As a result, demand for TOPCon and TOPCon+ is higher. Despite the complexity, he stressed that LAPLACE remains fully compatible with TOPCon+ and XBC integration.

Patent-Safe Tech For Global Sales

Dr. Josua Stückelberger, Director of Technology – International Business Unit at LAPLACE, speaks @TaiyangNews Conference

Dr. Josua Stückelberger, Director of Technology – International Business Unit at LAPLACE, highlights how the company ensures patent security for its customers. He stressed that LAPLACE’s proprietary LPCVD with ex-situ doping technology enables seamless adoption of innovations and allows customers to sell in the US and Europe without patent concerns.

ITRPV Forecasts 750 GW DC Shipments for 2025

Silver consumption is expected to fall further in PV production as per ITRPV's Markus Fischer

In 2024, the solar sector used around 6.15 tonnes of silver, equivalent to 9 mg per watt for 703 GW DC of modules shipped at $0.08/W. Actual installations, however, were 570 GW DC. With tandem cell technologies on the horizon, silver consumption is expected to fall further, thanks to their higher efficiency and reduced silver requirement per watt. ITRPV’s Steering Committee Chair, Markus Fischer, says that silver is not going to be in short supply. For 2025, ITRPV forecasts 750 GW DC of module shipments at $0.09/W, while installations are likely to range between 560 GW DC and 650 GW DC.
