Specialist gallium arsenide (GaAs) PV manufacturer Alta Devices, a subsidiary of Hanergy Group, has achieved another new solar cell conversion efficiency record of 29.1%, which was certified by Fraunhofer ISE CalLab.
Technology investments into advanced PV cell manufacturing have been at record levels in the past few years, with high-efficiency concepts seeing investment levels not seen since the days of turn-key thin-film lines a decade ago.
Panasonic Eco Solutions of North America and SolarEdge Technologies have teamed to offer the Panasonic ‘HIT’ (Heterojunction with Intrinsic Thin layer) ‘S Series’ PV module, using power optimizers that offer greater design flexibility for higher power efficiency and lower installation costs with a higher ROI.
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.
Manz launched its third generation ‘SpeedPicker’ 3.0 from its SAS series equipment for the specific handling of crystalline silicon wafers in the manufacturing of solar cells. SpeedPicker provides an automation solution for almost contact-free handling of solar cells throughout their entire production process.
Meyer Burger’s patented SmartWire Connection Technology (SWCT) uses a patented foil-wire electrode with up to 24 round wires to electrically interconnect solar cells and is said to set a benchmark in terms of module performance and low manufacturing costs within the ‘Ibex’ SWCT stringer system.
PV module equipment measurement specialist Endeas Oy has developed a new method to measure the steady-state I-V curves in PV modules using high-efficiency solar cells such as PERC, and especially HJT or IBC as solar simulators currently in production applications have limited accuracy, according to the company.
China-based integrated polysilicon and merchant cell manufacturer Tongwei Group expects to begin pilot production of heterojunction (HJ) solar cells by the end of 2018, while the success of its 200MW Industry 4.0 fully-automated solar cell production line will lead to a longer-term migration of all cell production to intelligent manufacturing.
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.
Leading PV manufacturing equipment supplier Meyer Burger has secured an order for its ‘SmartWire Connection Technology’ (SWCT) from an international solar module manufacturer in Southeast Asia for use with heterojunction (HJ) solar cells.
Leading PV manufacturing equipment supplier Meyer Burger has said that the pioneer of heterojunction solar cell technology, Panasonic has decided to fast-track the evaluation of its ‘SmartWire Connection Technology’ (SWCT) in an effort to boost its cell and module performance.
