Ahead of DuPont speaking at the PV CellTech 2018 meeting in Penang, Malaysia on 13-14 March 2018, PV Tech spoke with Guangyao Jin, Chief Scientist at DuPont Photovoltaic & Advanced Materials, on the company’s views on PV cell manufacturing.
Taiwan-based materials suppliers are benefiting from increased demand for diamond wire cut wafers for higher efficiency solar cells that is supporting higher prices in recent months.
Although profitability for many remains elusive sales have rebounded in September.
Conductive inks specialist PV Nano Cell is joining forces with major materials firm, Merck to develop and deploy its single-crystal, nanometric inks such as copper and silver to expand its applications.
Wickon Hightech has developed a new model of the ‘SPEEDFilm’ inspection platform specifically for PV manufacturers. The ‘SPEEDFilm Solar’ system ensures 100% inspection of screen printed paste structures with a very high throughput that is able to handle thinner and thinner printed structures on c-Si solar wafers.
After several months of lacklustre sales from many key PV manufacturers in Taiwan, indicating an expected boom in China’s downstream PV market had yet to gain momentum, March sales data indicates improving market demand, yet not at the levels seen in the prior year quarter.
Major metallization paste producer Heraeus Photovoltaics said its recently launched ‘SOL9631J’ series front-side metallization paste had been adopted by leading ‘Silicon Module Super League member, JinkoSolar.
Heraeus Photovoltaics has launched a new PERC (Passivated Emitter Rear Contact) metallization paste. The SOL9631 front-side paste has a new and unique glass chemistry combined with a new organic vehicle system. Due to a denser microstructure it is tailored for ultra-fine line printability for screen printing.
Heraeus Photovoltaics will be featuring its new range of metallization pastes for PERC-solar cells as well as for low-temperature heterojunction and organic solar cell applications at Intersolar Europe 2016.
DuPont Photovoltaic Solutions developed and launched a new advanced ‘DuPont’ ‘Solamet’ PV19B photovoltaic metallization front side paste that has a highly conductive silver composition and part of the PV19x family of pastes, with innovative material science which enables finer line design and excellent printability.
Major metallization paste producer Heraeus Photovoltaics' new APAC Technology Development Center (APAC TDC) in Shanghai, China is aiming to further reduce lead times for product modifications and deliveries to around only one week.
Silicon heterojunction solar cells demonstrate key advantages of high conversion efficiency, maximum field performance and simplicity of processing. The dedicated materials, processes and technologies used for the metallization and interconnection of this type of cell are reviewed in this paper.
Major PV metallisation paste producer Heraeus Photovoltaics says it has bolstered its multi-supplier sourcing strategy for silver powder after an accident in early January 2016 at one of the largest producers, Dowa Hightec, left two workers dead and two injured. The plant was subsequently shut down and could be out of commission for several months, pending investigations.
