During the past few years, the migration from multi to mono, replacing Al-BSF p-type cells with rear passivation layers (PERC), and having the capability of bifacial light absorption, have been the very obvious technology shifts seen within the PV industry.
Major PV materials supplier Heraeus Photovoltaics has collaborated with German company, Cell Engineering to develop metallisation pastes for its ‘LECO’ (Laser Enhanced Contact Optimization) technology that can increase multiple solar cell architectures conversion efficiencies by up to 0.15%.
PV is increasingly becoming the cheapest energy source and therefore has become the energy source with the highest yearly capacity additions! Even in 2018, after some scepticism right after SNEC 2018, due to the announcement of the Chinese Government to stop supporting PV as intensively as in 2017, more than 100GW (109GW) have been installed worldwide (we actually bet a crate of beer on that!) and 125GW has been forecasted to be installed in 2019.
PV CellTech 2019 takes place in Penang, Malaysia on 12-13 March 2019, and once again will feature keynote presentations from CTOs and heads-of-R&D from the leading multi-GW cell producers of the industry in 2019.
European research and innovation hub centre imec has detailed a path for its nPERT (n-type Passivated Emitter and Rear Totally diffused) solar cell technology to reach conversion efficiencies in excess of 24% for volume production applications.
Jolywood (Suzhou) Sunwatt Co., (Jolywood) has introduced several new innovations into its N-type monocrystalline bifacial modules that boost cell and module efficiencies, improve durability while lowering balance of material (BOM) cost and overall levelized cost of electricity (LCOE).
As the solar industry has grown from a 50GW market to 100GW in just a few years, the desire to have differentiated production has increased, especially for companies entering the market or repositioning strategies.
Henkel Adhesive Electronics has developed a series of ECAs (electrically conductive adhesives) designed to facilitate lower-cost, improved reliability and process-friendly assembly of solar devices. The LOCTITE ABLESTIK ICP 8000 series ECAs have been designed to elevate module performance and accommodate various assembly processes including cell interconnect ribbon bonding and shingled solar modules.
The International Solar Energy Research Center Konstanz e.V. (ISC Konstanz) has signed a technology transfer agreement with PV module assembly equipment supplier based in Finland for R&D centre’s advanced ‘BiSoN’ (Bifacial Solar cell On N-type) and ZEBRA (diffused n-type IBC) solar cell technology.
Specialist semiconductor and PV equipment supplier Intevac reiterated that its 12 unit ‘ENERGi’ solar ion implant tool order valued at around US$23 million that was booked in March, 2017 remained in its order backlog at the end of the first quarter of 2018.
Specialist semiconductor and PV equipment supplier Intevac has reported delays in supplying a 12 unit order for its ‘ENERGi’ solar ion implant tool to a customer in China planning to ramp N-type mono IBC (Interdigitated Back Contact) solar cells and modules.
