Major polysilicon and merchant solar cell manufacturer, Tongwei Group and subsidiary Tongwei Solar are to significantly increase high-purity polysilicon production and high-efficiency solar cell production over the next five years.
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.
The fifth PV CellTech event takes place in Penang, Malaysia on 10-11 March 2020, and will be happening at a time when PV is going through its most dramatic realignment yet, in terms of manufacturers dominating the cell supply landscape, and the technologies being deployed in mega mass-production.
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 module and major backsheet manufacturer, Jolywood (Suzhou) Sunwatt Co, reported a strong rebound in revenue and profits in the second quarter of 2019, with first half year results tempered by a weak first quarter.
Major PV materials supplier Heraeus Photovoltaics had launched six, next-generation, high-performance metallization pastes at this year’s SNEC PV Power Expo, which characterises the rapid pace of the upstream PV industry’s renewed focus on technical advancements and cost reductions.
Trina Solar has launched a new high-performance module series using large-area n-Type monocrystalline TOPCon (Tunnel Oxide Passivated Contact) cell technology in both half-cut 144 (72-cell) and 120 half-cut (60-cell) configurations.
‘Solar Module Super League’ (SMSL) member, Trina Solar has set a conversion efficiency record of 24.58% for an i-TOPCon (Industrial Tunnel Oxide Passivated Contact) bifacial solar cell using a super-sized 244.62 cm2 wafer.
‘Solar Module Super League’ (SMSL) member Risen Energy has recently reported a decline in 2018 annual revenue and net profit, due to the overall decline in PV installations in China, which also led to pricing pressure across its PV module, PV encapsulant and EPC business divisions.
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.
‘Silicon Module Super League (SMSL) leader JinkoSolar has achieved a record conversion efficiency of 24.2% for a large-area N-type TOPCon (Tunnel Oxide Passivated Contact) solar cell, verified by the Photovoltaic and Wind Power Systems Quality Test Center at the Chinese Academy of Sciences (CAS).
