TIANJIN, China, May 25, 2026 /PRNewswire/ -- TCL Zhonghuan ("TCL Zhonghuan Renewable Energy Technology Co., Ltd.") announced the launch of its next-generation BC (back-contact) high-efficiency module at its Tianjin manufacturing base this month, marking a major milestone as the company transitions BC technology from advanced development into large-scale commercial production. Featuring a unique combination of proprietary BC architecture and in-house silicon wafer technology, the new module delivers up to 25.2% module efficiency and 680W power output, offering a high-performance solution for utility-scale and commercial & industrial (C&I) solar applications.

The launch further strengthens TCL Zhonghuan's position in next-generation PV technology and underscores its commitment to driving higher efficiency, greater reliability, and lower lifecycle energy costs across the solar industry.

Advancing BC Technology Through Integrated Innovation

Unlike conventional BC products available in the market, TCL Zhonghuan's BC platform is built on a fully integrated technology foundation spanning wafers, cells, and modules. The company's competitive advantages include a robust portfolio of more than 1,600 foundational BC patents, dedicated BC wafer development, and decades of research and manufacturing expertise.

The newly launched modules are manufactured using TCL Zhonghuan's proprietary high-efficiency silicon wafers. Based on the company's advanced low-carbon wafer technology platform, these wafers feature minority carrier lifetimes exceeding 1,000 μs, providing an ideal foundation for high-efficiency BC cell architectures. Combined with an optimized cell design, the technology supports conversion efficiencies exceeding 27% at the cell level while maintaining a temperature coefficient as low as -0.26%/°C.

To further enhance system reliability, TCL Zhonghuan has introduced a next-generation hotspot mitigation design that can reduce hotspot temperatures by up to 50°C compared with conventional modules. The modules also demonstrate excellent low-irradiance performance, with a weak-light response factor exceeding 95%, enabling stable energy generation under diverse operating conditions.

Setting a New Benchmark for High-Efficiency Modules

The new N-type BC modules combine TCL Zhonghuan's proprietary N-type wafer technology with advanced BC cell architecture, delivering strong performance across multiple dimensions.

With a mass-production efficiency of up to 25.2% and maximum power output reaching 680W, the modules are on par with mainstream BC products in terms of power rating. They incorporate enhanced resistance to fire risk, partial shading, and dust accumulation, while offering a 30-year linear power warranty and a 15-year product warranty.

The modules also achieve a bifaciality factor of 80% ± 5%, enabling higher rear-side energy generation and increased overall energy yield. Long-term reliability has been further strengthened through advanced PID-resistant design, limiting lifecycle power degradation to below 1% under testing conditions. The products have successfully passed rigorous certification and validation processes conducted by internationally recognized testing organizations.

In addition to performance advantages, the modules feature a busbar-free front surface that creates a clean, all-black appearance, making them particularly suitable for BIPV and premium rooftop applications. Their versatility also allows deployment across utility-scale, commercial, and distributed generation projects, helping customers reduce LCOE and maximize long-term project value.

Reinforcing Leadership in BC Technology

As an early pioneer and long-term innovator in BC technology, TCL Zhonghuan has leveraged more than four decades of semiconductor materials expertise and extensive photovoltaic manufacturing experience to establish a distinctive BC technology platform. By combining advanced BC cell architecture with proprietary strengths in large-format wafers, N-type materials, and intelligent manufacturing, the company has created a vertically integrated innovation ecosystem that accelerates technology commercialization and performance improvement.

TCL Zhonghuan possesses one of the industry's most comprehensive BC intellectual property portfolios. Since achieving the world's first commercial-scale production of IBC cells in 2004, the company has continued to expand its innovation footprint, securing more than 1,600 globally authorized BC patents covering crystal growth, cell structures, manufacturing processes, and module packaging technologies.

As global demand for high-efficiency solar solutions continues to grow, TCL Zhonghuan remains committed to advancing solar innovation through continuous technology development and manufacturing excellence. Working closely with customers and industry partners worldwide, the company will continue to accelerate the adoption of next-generation PV technologies and contribute to a more sustainable, low-carbon energy future.

Zwölf Jahre Bühnenabstinenz und dann ein Neustart im Rockabilly-Tempo: Dick Brave, die Kunstfigur des deutschen Popsängers Sasha, ist nach langer Auszeit nach Stuttgart zurückgekehrt. Im Wizemann eröffnet er den Abend mit „Back for Good“ von Take That – ein programmatischer Einstieg, der das versprochene Comeback bereits im Titel trägt. Brave, der seine Rock’n’Roll-Persona Anfang der 2000er-Jahre etablierte, setzt damit an die Zeitreisen an, mit denen er seit 2002 das deutsche Publikum bedient: bekannte Pop- und Rocksongs werden konsequent auf einen Retro-Sound ausgerichtet.

Musikalisch trägt ihn dabei eine eingespielte Formation: The Backbeats. Ein Kontrabassist, der nur kurz zum E‑Bass wechselt, ein Pianist mit hoher Anschlagsdichte, knallige Gitarren und ein Schlagzeuger, der den geradlinigen Beat betont, formen das Fundament. Das Repertoire reicht von Originalen der 1950er- und 1960er-Jahre bis zu aktuellen Popsongs, die Brave im Rockabilly-Stil neu zeichnet. Dabei versteht er sich laut Auftrittsbeschreibung gleichermaßen auf historisches Material wie auf moderne Charttitel, denen er ein „knapp geschneidertes Rockabilly-Hemd“ überstreift.

Konkrete Beispiele dieser Transformation liefert das Set im Wizemann reichlich. „Take On Me“ von a‑ha beginnt er in einer langsamen, rhythmischen Doo-Wop-Version, verziert mit Jodlern und später angezogenem Tempo. George Michaels „Freedom“ wird zu einem Cowboystück umgebaut, während Taylor Swifts „Shake It Off“ mit hämmerndem Piano und zuckenden Gitarren in Szene gesetzt wird. Brave behauptet dabei augenzwinkernd, die US-Sängerin persönlich getroffen zu haben – ein Verweis auf die Kunstfigur, der seinen Auftritten eine zusätzliche erzählerische Ebene gibt.

Im weiteren Verlauf des Abends tauchen Dick Brave and the Backbeats tiefer in die Vergangenheit ein und holen Elvis Presley musikalisch auf die Bühne. Versammelt um ein einziges Bühnenmikrofon, agieren sie deutlich leiser als im übrigen Programm, setzen jedoch auf Authentizität und Nähe. Titel wie „All Shook Up“ und „Teddy Bear“ werden so zum kompakten Rock’n’Roll-Block, der den historischen Kern des Projekts betont: eine stilisierte, aber handwerklich präzise Rückübersetzung moderner Popkultur in die Ästhetik der 1950er- und 1960er-Jahre.
