Hanwha Q CELLS' product portfolio delivers market-leading anti-LeTID performance in Fraunhofer CSP
Fraunhofer CSP Test Results
Both half-cell monocrystalline Q.PEAK DUO modules and multicrystalline Q.PLUS modules demonstrate market-leading anti-LeTID performances
Fraunhofer CSP independently tested two batches of nine different types of modules for in high-temperature conditions of up to 75 degrees Celsius
Hanwha Q CELLS Co., Ltd. CTO Daniel Jeong remarked: "The performance of our Q.PEAK DUO and Q.PLUS modules demonstrates Hanwha Q CELLS' continued commitment to tackling the toughest challenges in the industry and highlights the importance of focusing our R&D efforts in areas where we can deliver the most added value to our customers."
BERLIN, Dec. 6, 2018 /PRNewswire/ -- Hanwha Q CELLS (collectively referring to Hanwha Q CELLS Co., Ltd. (NASDAQ: HQCL) as well as Hanwha Q CELLS & Advanced Materials Corporation) (or the "Company"), one of the largest solar cell and module manufacturers in the world, today confirmed that its leading range of solar modules have delivered exceptional performance in a recent test conducted by Fraunhofer Center for Silicon Photovoltaics (CSP) to benchmark light and elevated temperature induced degradation (LeTID) in solar cells.
Hanwha Q CELLS' modules were tested by Germany's Fraunhofer CSP and found to display negligible power loss during high-temperature testing conditions of up to 75 degrees Celsius. Both Hanwha Q CELLS' half-cell monocrystalline Q.PEAK DUO modules and multicrystalline Q.PLUS modules exhibited market-leading anti-LeTID performances among the nine module types tested (comprising seven mono-Si and two multicrystalline silicon modules), including modules produced by various leading solar brands. The final test batch included two modules from each category, resulting in 18 different measurements.
The results of this test were presented at the EU PVSEC conference in September titled: Benchmarking Light and Elevated Temperature Induced Degradation (LETID).
Hanwha Q CELLS: anti-LeTID pioneer and market leader
The effects of light induced degradation (LID) on PERC (passivated emitter rear cells) solar technology are well-known in the PV industry, and are tested for during standard IEC certification of solar cells. However, LeTID -- which is a degradation effect identified on both monocrystalline silicon (Cz-Si) and multicrystalline silicon (mc-Si) cells at temperatures above 50 degrees Celsius -- can account for cell degradation of up to 10%, but is less understood across the industry.
Hanwha Q CELLS was the first solar cell developer in the industry to link the degradation of PERC cells to high temperatures and was thus the first company to devise a solution to suppress LeTID in 2015, using its Q.ANTUM cell technology that suppresses LID as well as LeTID. While the exact root cause of LeTID is still a topic of much debate among photovoltaic researchers, Hanwha Q CELLS' Yield Security pledge guarantees that the Company's mono and multi Q.ANTUM products are certified anti-LeTID -- a claim that few other manufacturers can make.
