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.
Talesun has launched a new double glass photovoltaic panel with aluminum frame that has achieved TÜV certification. The ‘TWINKLE’ (TD660P) 60-cell multicrystalline panel uses the aluminum frame as the sealing point for the panel’s edges, the double glass modules are therefore weather-resistant and easier to install and transport.
SMA Solar Technology has started offering the SMA Power+ Solution, which combines SMA inverter technology and intelligent PV module optimization in a cost-effective, comprehensive package. The basis of the intelligent SMA solution is the new Sunny Boy 3.0-5.0 with the new SMA Smart Connected service.
SCHMID has launched a cost-effective process for the texturing of diamond-wire cut multi-c-Si wafers that can be easily integrated into existing production lines. DW PreTex is being made available in two versions: as a separate single unit that roughens the surface of the wafers and then uses the available texture capacity, or as a combined line for complete texturing. Based on an in-line wet process, the process is suitable for both wafer and cell manufacturers.
Growatt has launched its new generation, three-phase solar inverter series, the Growatt 8K-11KTL3-S. The new inverters are designed with maximum efficiency of 98.4% and MPPT efficiency 99.5%, as well as a wide DC voltage range of 160-1000VDC, which maximizes the comprehensive efficiency of the inverter and provides longer electricity generation.
Aurora Solar Technologies has introduced an enhanced version of its ‘Decima’ inline measurement system for quality control of bi-facial solar cells during production. ‘Decima Gemini’ consists of a specialized pair of Decima CD measurement heads that enables the sheet resistance of the wafers' back-surface field and emitter to be measured accurately and simultaneously.
Fraunhofer ISE has developed a new software tool that determines the cell-to-module (CTM) effects that occur when solar cells are integrated into a module. The SmartCalc.CTM software enables manufacturers of PV modules and materials to optimize the assembly and material combination in a PV module before fabricating a prototype.
