Set micro-grid news, the world's leading supplier of metallized solar PV industry Heraeus photovoltaic recently announced that with China's solar wafer manufacturer Rongde New Energy Co., Ltd. signed a comprehensive cooperation agreement under which the agreement will Rongde new energy Heraeus's latest high-purity SiO2 diffusion coating, HeraGlaze®, is used to upgrade its manufacturing process for the mass production of polysilicon wafers, marking the beginning of Heraeus's move to the upper reaches of the PV value chain An important step.
The first step in photovoltaic cell production is the melting of the polycrystalline silicon ingot to form a silicon ingot, and HeraGlaze®, which Heraeus successfully developed in 2017 as a breakthrough in the process, offers the HeraGlaze® Non-diffusive coatings help Sonder New Energy increase wafer capacity by 3% and cell efficiency by 0.05%. HeraGlaze® is applied as a non-diffusive coating to the porous surface of crucibles to dramatically increase ingot and final product (solar silicon Sheet.) HeraGlaze® acts as a barrier to the ingress of impurities, such as iron, from melting into the ingot during the melting and crystallization of the ingot.As the coating increases the availability of the ingot Cross section, Rongde new energy silicon production will increase 3%, its customers battery efficiency will increase 0.05%, making Rongde new energy in the fierce price competition with monocrystalline wafers to stabilize its leading market of polycrystalline silicon Share.
• Continued increases in wafer throughput and cell efficiency • More concentrated conversion efficiency for polysilicon PERC backslugged cells • Reduced iron impurity content and LID effects to absorb more solar energy.
In addition, Heraeus PV will also work with Rongde New Energy to develop a number of cutting-edge research and development projects on the new generation of highly efficient silicon based HeraGlaze® technology Dr. Zhang Weiming, senior vice president and chief technology officer of Heraeus photovoltaic : 'Rongde New Energy and Heraeus share the common belief that promoting the popularization of solar energy needs the cooperation of all walks of life, which is an important reason for both parties' commitment to long-term cooperation. HeraGlaze® will manufacture wafer for Rongde New Energy The process has led to subversive changes that have helped the latter solidify its lead in the 'fully melted' polysilicon manufacturing process.
