Enhancing quality control in PV cell production was a key topic at PV CellTech 2018. After the conference, we caught up with Gordon Deans, founder and chief operating officer of inline solar cell measurement equipment specialist Aurora Solar Technologies to discuss some of the requirements when moving towards smart factories.
Researchers at Solliance and ECN have fabricated a 6 inch industrially processed c-Si cell with a perovskite top layer that is mechanically stacked using ECN’s MWT-SHJ (metal-wrap-through silicon heterojunction) design that has achieved conversion efficiencies of 26.3%. The work was published during the Silicon PV/nPV conference, in Lausanne, Switzerland.
Researchers at the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) have announced the development of a significantly low-cost technique to texture nanoscale features on multicrystalline silicon (mc-Si) wafers after diamond-wire wafer cutting.
Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar is planning further capacity expansions across wafer, cell and module assembly in 2018, including a module assembly plant in the US, after strong capital expenditures in 2017 that totalled US$480 million.
As previously reported there was a significant slowdown in global solar PV manufacturing capacity expansion announcements in the third quarter of 2017, which we highlighted was hardly surprising due to significant level of expansions plans announced in the first half of the year. However, despite increased concerns over the potential imposition of restrictive trade practices in the US and India in the fourth quarter of 2017, there was a significant rebound over the previous quarter, leading to the highest recorded gigawatts of new expansion announcements.
‘Silicon Module Super League’ (SMSL) member Canadian Solar may not be expecting any shipment growth in 2018, yet significant revenue growth is expected from selling a major part of its US$1.5 billion PV power plant assets.
‘Silicon Module Super League’ (SMSL) member Canadian Solar has lowered nameplate capacity expansion plans in 2018 for both in-house solar cell production and module assembly as total module shipment guidance for 2018, indicates marginal growth.
Leading polysilicon and solar wafer producer GCL-Poly Energy Holdings has reported a significant increase in nameplate wafer capacity in 2017, going from 18.5GW in 2016 to 30GW at the end of 2017, a 62.2% rise.
Advanced doping technologies for high efficiency n-type cell architectures was a key topic at PV CellTech 2018. After the conference, we caught up with Christian Buchner, Vice President of the Photovoltaics BU at leading PV equipment supplier SCHMID Group, to tap into some key takeaways.
OPES Solutions a supplier of off-grid solar modules for grid independent power supply, has developed an ultra-light solar module together with the Fraunhofer Center for Silicon Photovoltaics CSP. The new ultra-light solar module reduces module weight by two thirds when compared to conventional crystalline modules.
Aurora Solar Technologies has introduced the ‘Veritas Insight’, a new product that is designed to provide a fully integrated quality control system for high-efficiency solar cells such as PERC (Passivated Emitter Rear Cell).
‘Silicon Module Super League’ (SMSL) member JA Solar is getting closer to de-listing from NASDAQ and going private after over 90% of the ordinary shares held had voted to agree a merger with its Cayman Islands registered parent company, owned primarily by JA Solar’s founder, chairman and CEO, Baofang Jin.
