In defiance of a significant trend by a growing number of leading PV manufacturers to either completely replace P-type multi c-Si cell technology with P-type mono c-Si with PERC (Passivated Emitter Rear Contact) technology, or hedge their bets and do PERC on both wafer substrates, Silicon Module Super League member Canadian Solar is placing a potentially risky bet on pushing ahead with the migration to P-type multi c-Si PERC cell technology using diamond wire saw (DWS) and ‘Black Silicon’ texturing under its ‘ONYX’ cell branding.
Specialist PV manufacturing equipment supplier RENA Technologies has secured several major orders from Asia-based PV cell manufacturers for its alkaline texturing and junction isolation tools in the first quarter of 2017.
Leading PV manufacturing equipment and technology supplier Meyer Burger has recently announced a swathe of new orders that encompass diamond wire saw equipment, PERC upgrade technology and Heterojunction (HJT) cell technology.
PV manufacturing equipment specialist SCHMID Group has launched a new texturing tool for diamond-wire-cut multi-c-Si wafers that has already secured orders in the 500MW range and expects significant order intake through the first half of 2017.
While there is no shortage of leading indicators in the PV industry that can be used to predict future trends in manufacturing and across the various companies involved in this space, one of the most pertinent ones relates to capital expenditure (or capex).
Solar cells produced using p-type multi c-Si wafers retained their dominant market-share position in 2016, despite significant investments into p-type mono and advanced cell production, such as PERC. The transition to increased mono wafer use is now expected to be seen more clearly during 2017 and 2018, but depends still upon the relative end-market demand from the domestic Chinese market.
Taiwan-based multicrystalline wafer producer Green Energy Technology (GET) has said had terminated a sub-contracting wafer supply deal with another Taiwan-based wafer producer, Eversol Corporation
According to the ongoing analysis of global PV manufacturing capacity expansions by PV Tech, high-efficiency solar cell migrations, whether monocrystalline or multicrystalline with PERC (Passivated Emitter Rear Contact) and N-type mono heterojunction (HJ) have been gaining strong momentum since 2015.
Key Taiwan-based PV manufacturers have reported December, 2016 sales and indicated fourth quarter and full-year sales figures, which were primarily impacted by a slump in demand in the second half of the year.
Leading polysilicon and wafer producer GCL-Poly reported a 15% cut in production of polysilicon in the third quarter of 2016, compared to the prior year period, due to weak China end-market demand.
