UtmoLight Leaps Ahead in Trillion-Yuan Photovoltaic Market with Launch of 3 Game-changing Techniques

WUXI,China,May 13,2021 -- Wuxi UtmoLight Technology Company ("UtmoLight" or "the Company"),a world-leading perovskite photovoltaic module company,held a press conferenceon May 13in Wuxi,Jiangsu Provinceto launch itsinnovative perovskitephotovoltaictechnology. The integrated solutions,named Utmorigin,can ensurelarge-area preparation,high efficiency and high stabilityof perovskite solar cells and include three novel techniques.

During the conference,UtmoLight signed strategic cooperation agreementswith partners including SVOLT,anemergingforce inlithium batteries,FTXTwho specializes in hydrogen energy and fuel cell technology,as well asGreatwall Estate. Together they will explore the applicationof perovskite solar technologyin hydrogen production,energy storage,green constructionand estabilish an ecological circle of green energy.

According to Dr. Zheng Ce,co-founder and deputy general manager of UtmoLight,"Methylamine-free perovskite solar cells warrant higher efficiency and better stability in theory,but large-area preparation of methylamine-free perovskite film has been a challenge for the industry. In addition to the optimal precursor proportions from theoretical calculations,the UtmoLight formulation contains phase stabilizer and passivation agents which guarantee the stability,high efficiency and large-area preparation of perovskite solar cells."

"In-situ filmcrystalization" is an innovative preparation techniqueforlarge-area,high-quality and high-stabilityperovskite film layer. The technique ensures satisfying conformity and yield,and is compatible with perovskite-silicon tandem cells. The nanoparticleconductive ink for the charge transport layer is made from a uniqueformulation by UtmoLight. The charge transport layer made from the ink is highly conductive,dense and protects the perovskite layer,thus improvesthe conversion efficiency and long-term stability of perovskite solar cells," added Dr. Zheng.

Adopting these techniques,UtmoLight perovskite solar modules achieve a certified efficiency of 20.5% with an area of 63.98cm². Thisefficiency record leadsthe industry by a wide margin. Presently,the team is also applying thesametechniques to30cm2 perovskite modulesand expects to exceed 19% efficiency soon. Meanwhile,construction of a pilot line of one-square-meter size perovskite modules is commencing in the third quarter of 2021with the product expected to reachmarket next year.

UtmoLight is invested by Great Wall Holdings,and is engagedinthe commercialisation of perovksite photovoltaics,optoelectronics and materials. UtmoLight takesinnovation asitsdriving force,industrialization as itspropulsion,and endeavors totransform energy and build a green ecology.
