XI'AN, China, April 25, 2026 /PRNewswire/ -- Taiyang News, a globally authoritative photovoltaic media outlet, officially released its April 2026 edition of the "TOP SOLAR MODULES LISTING". LONGi's EcoLife series modules (LR7-54HJD-510M), built on HIBC technology, have firmly claimed the top spot with a mass production efficiency of 25%. This milestone marks international recognition of LONGi's innovation strength in the back-contact (BC) technology pathway and ushers in a new "25%+" era for PV module efficiency.

Since 2022, Taiyang News has published its monthly "TOP SOLAR MODULES Listing," now widely recognized as an authoritative efficiency ranking in the global PV industry. The ranking imposes stringent inclusion criteria: only products that have achieved large-scale mass production, have complete technical data, and deliver conversion efficiency of ≥21.5% are considered. Moreover, all data must come from commercial products already delivered to end customers. With "real and deliverable" as its baseline, the ranking holds high industry reference value and credibility, serving as a barometer for global PV module efficiency levels. LONGi's top position proves that its HIBC products have reached the world's highest efficiency in real mass production.

Behind this achievement lies LONGi's persistent efforts in BC technology. HIBC (High-temperature/Low-temperature Hybrid Interdigitated Back-Contact) cell technology is a major innovation along LONGi's BC roadmap. It combines the high passivation performance of heterojunction (HJT) technology with the superior light utilization of the back-contact structure, achieving the world's first mass production of such modules. In April 2025, the ISFH (Institute for Solar Energy Research in Hamelin) certified LONGi's HIBC cell efficiency at 27.81%, setting a new world record for this technology and approaching the theoretical limit of single-crystalline silicon cells.

Li Zhenguo, Founder and Chief Technology Officer of LONGi, commented: "This is another peak that LONGi has reached in technological innovation, as well as another major breakthrough in our BC technology journey. We have taken PV module efficiency to a significantly higher level, fully demonstrating the high scalability of BC technology and the substantial room for further efficiency gains."

The EcoLife series modules, designed specifically for residential applications, deliver a maximum power output of up to 510W. The EcoLife series modules increase the cell-to-module area ratio from 93.2% to 95.1%, thereby significantly enhancing light absorption. To address shading issues, the modules feature a unique quasi-bypass diode structure that enables current routing. Under shading, power loss is reduced by more than 70% compared to TOPCon products, making them highly resistant to soiling and shadows. With a leading power density of 250W/m², the modules effectively solve the challenge of generating more power on limited roof areas, substantially reducing household electricity costs.

Martin Green, known as the "Father of PV" and a professor at the University of New South Wales in Australia, has praised the technology: "On the 'Solar Cell Efficiency Tables' list, LONGi's HIBC technology dominates, taking the number one spot. This is also attributable to LONGi's persistent efforts on the BC technology track."

To date, LONGi's HIBC and BC series modules have gained extensive market validation worldwide. In January 2026, the LONGi EcoLife won the German Excellence Award 2026 in the "Energy & Environment" category. The jury's citation read: "LONGi EcoLife: Higher Power Generation, Higher Safety – Modules for an Uncertain Climate Future," specifically acknowledging the product's technical leadership and application value. In February, LONGi renewed a three-year framework agreement with Energy 3000, a well-known European energy solutions provider, to continuously supply a total of 2GW of high-efficiency PV modules, focusing on HPBC 2.0 and LONGi EcoLife modules based on HIBC technology.

At present, HIBC cell technology has already achieved large-scale mass production. LONGi has built a complete BC technology matrix ranging from HPBC 2.0 to HIBC. Moving forward, LONGi will continue to drive technological innovation, further boost module efficiency and power density through its BC technology platform, deepen global market applications of high-efficiency products such as HIBC, and strive to deliver more valuable clean energy solutions to customers worldwide, contributing to the global energy transition and the realization of carbon neutrality goals.

Die Aktien von Siemens haben zur Wochenmitte neuen Auftrieb erhalten. Am Montagvormittag stieg der Kurs an der Dax-Spitze um rund drei Prozent auf 250,30 Euro und markierte damit den höchsten Stand seit Mitte Februar. Zum Rekordhoch von knapp 276 Euro, das kurz zuvor erreicht worden war, bleibt zwar noch etwas Luft, doch die jüngste Analystenunterstützung schürt Erwartungen auf weitere Kursgewinne.

Auslöser der Bewegung ist eine neue Studie von Bernstein Research. Analyst Alasdair Leslie erhöhte sein Kursziel für den Technologiekonzern von 290 auf 300 Euro und bestätigte die Einstufung mit "Outperform". In seiner Analyse verweist er darauf, dass sich die Siemens-Aktie seit Jahresbeginn schwächer entwickelt hat als die Papiere von Wettbewerbern. Gründe dafür seien Sorgen über mögliche Auswirkungen von Künstlicher Intelligenz auf das Softwaregeschäft, kurzfristige Zyklusrisiken sowie die zunehmende Komplexität des Konzerns nach dem anstehenden Umbau.

Leslie hält diese Zurückhaltung des Marktes jedoch für nicht gerechtfertigt und erwartet in den kommenden sechs bis zwölf Monaten eine Neubewertung des Unternehmens. Aus seiner Sicht könnte eine Reihe von Kurstreibern den Bewertungsabschlag gegenüber der Konkurrenz verringern. Konkrete Details zu diesen potenziellen Treibern nennt die Studie zwar nicht, sie verweist aber darauf, dass Siemens vor einer Phase stehe, in der Investoren die Struktur und Ertragskraft des Konzerns neu einordnen dürften.

Zusätzliche Unterstützung für die Investmentstory sieht Bernstein in möglichen weiteren Aktienrückkäufen. Leslie erkennt Spielräume, um die Rückführung von Kapital an die Aktionäre auszuweiten. Dies könnte die Nachfrage nach der Aktie zusätzlich stützen und den vom Analysten erwarteten Prozess der Neubewertung am Markt beschleunigen. Die Kombination aus erhöhter Kurserwartung, unverändert positiver Einstufung und der Aussicht auf Kapitalmaßnahmen verleiht dem Siemens-Papier damit neue Dynamik.
