For Heraeus, the agreement represents a major step to expand its presence upstream in the solar photovoltaic value chain.<\/p>\n<p>Developed in 2017, HeraGlaze&reg; represents a breakthrough innovation the very first step of the of the solar cell manufacturing process, when poly-crystalline silicon blocks are melted into a single silicon ingot. To deliver the highest quality of the ingot and the eventual end product, the solar wafer, HeraGlaze&reg; is applied as a slurry on the porous surface of the crucibles. HeraGlaze&reg; acts as a barrier and prevents thermally-induced impurities, such as iron, from transferring from the crucible to the silicon ingot during the melting and crystallization of silicon. By increasing the usable section of the silicon ingot, Heraeus will be able to increase Rietech&rsquo;s wafer output yield by 3% and its customers&rsquo; cell efficiency by 0.05%. This will enable Rietech&rsquo;s multi-crystalline wafers to defend its market share against aggressive price competition from mono-crystalline wafers.<\/p>\n<p>In less than a year, the HeraGlaze&reg; coating has gone from the research lab to the real world to produce impressive results for wafer manufacturers, including:<\/p>\n<ul>\n<li>Consistent increases in yield and cell efficiency<\/li>\n<li>Tighter distribution of efficiency in multi-crystalline PERC cells<\/li>\n<li>Lower levels of iron, resulting in higher energy harvest due to lower light induced degradation (LID)<\/li>\n<\/ul>\n<p>Additionally, Heraeus Photovoltaics will work with Rietech on advanced research and development programs to produce the next generation of high-efficient wafers based on the HeraGlaze&reg; technology. Dr. Weiming Zhang, EVP and CTO of Heraeus Photovoltaics, said, &ldquo;Rietech and Heraeus both share the belief that advancing the adoption of solar energy cannot occur in isolation, which is why we are committed to working together. HeraGlaze&reg; can be a game-changer for Rietech&rsquo;s wafer manufacturing process and will help them consolidate their leadership in &lsquo;full-melt&rsquo; process for manufacturing multi-crystalline wafers.&rdquo;<\/p>\n<h5 class=\"green\">Source<\/h5>\n<p><span><a href=\"https:\/\/www.heraeus.com\/en\/hpt\/press_media_photovoltaics\/photovoltaics_news_2017\/11_heraglaze.aspx\"
