Heraeus Photovoltaics has introduced specially developed metallization pastes for ‘knotless screen’ printing of solar cells. The new SOL9641AX/BX series is designed to realise the full advantages of knotless printing screens and were developed in close collaboration with screen vendors and customers.
Sungrow’s 1500VDC string inverter is designed to significantly reduce installation and balance of system costs for utility-scale PV systems. Sungrow was the first inverter manufacturer to introduce a 1500VDC string inverter with its SG80HV, which has a power output of 80KW. The latest inverter, SG125HV, puts 125kW of capacity in a suitcase-sized cabinet weighing just 68kg. At a higher rated voltage, the SG125HV is claimed to further reduce installation and balance of system costs.
PLANT PV, has introduced its first major product to enable significant improvements in conventional solar cell power output. PLANT PV’s new ‘Silver-on-Aluminum’ paste is designed for easy implementation with no added investment cost for cell producers and is claimed to lead to a 1% increase in relative power output for c-Si solar cells. The company, which was incubated out of the Molecular Foundry at Lawrence Berkeley National Laboratory, will present its Ag-on-Al paste concept and test results at the SNEC 11th International PV Power Generation Conference in Shanghai, China.
Singulus Technologies has launched its new ‘GENERIS’ PVD inline sputtering system for heterojunction (HJ) solar cells. The system is suited for challenging transparent conductive oxides (TCO) layers like ITO and AZO hat can produce HJ cells with conversion efficiencies of more than 22%, as well as reduce manufacturing costs. New system will be presented at SNEC 2017 in Shanghai, China.
Alfartec has introduced its BlueSky-MT240 solar simulator to the market that is based on LED and Halogen technologies, making it ideal for production, research and certification centers, globally. Its long flash duration up to 500 millisecondes and short cycle time are suitable for all module technologies.
Ingeteam has launched its new PV string inverter, which will make it possible to achieve a power output of 100kWAC in a single, 75kg unit. This new three-phase inverter comes under the name ‘INGECON SUN 100TL’, and is suitable for indoor and outdoor installations and is primarily directed at commercial, industrial and large-scale projects.
REC Group has introduced an all-black variant of its ‘TwinPeak 2’ Series PV module for US and European residential markets. The REC TwinPeak 2 BLK2 Series has a nominal power rating of up to 285Wp, using its half-cut cell and PERC (Passivated Emitter Rear Cell) technology and uniformly black-colored multicrystalline cells.
Sharp is making available its NQ-R256A (256W) monocrystalline PV module to the European market, which incorporates back contact cell technology for efficiencies of 19.8%. The 48-cell configuration has proved popular in Japan and can maximize rooftop area, compared to conventional 60-cell configured modules.
von Ardenne’s ‘SCALA’ platform has been designed to close the gap between R&D and production of Silicon heterojunction (HJ) solar cells. The modular platform provides a pathway via a technology approach, the tuning of the PVD processing and the complementary technology steps such as texturing, PECVD and metallization processes for 22% conversion efficiencies on 6-inch substrates and thus to ease the path to commercialization.
