Manz showcased its new equipment for wet-chemical processing of crystalline silicon solar cells at SNEC 2012 in Shanghai this May. The IPSG CEI 4800 is designed for chemical edge isolation (CEI) and phosphor silicate glass (PSG) post process removal. The tool is capable of handing 4800 wafers per hour and sold as a bundle with the Manz SpeedPicker for loading and unloading.
Konica Minolta Sensing Americas has introduced the AK-300 PV Reference Cell, which is claimed to be the world's first for dye-sensitized solar cells. The AK-300 was developed in conjunction with the National Institute of Advanced Industrial Science and Technology (AIST) and utilized Konica Minolta Sensing’s advanced optical filter technology. The reference cell has been designed using an optical filter mounted on a stable crystalline silicon solar cell rather than using traditional dye materials.
Teamtechnik is to debut its new stringer system at SNEC PV 2012. The ‘STRINGER TT1200 HS’ is claimed to solder crystalline solar cell strings in a 2.5 second cycle on just one track. Compared to its previous model throughput, it has been boosted by 200 cycles and is claimed to currently be the fastest single-track stringer system on the market.
Eyelit has made available its ‘Intelligence Mobile Web Portal,’ which provides operational information in real-time through tablet devices and smart phones using iPhone, Android, or BlackBerry technologies, enabling ‘anywhere access’ to key manufacturing and quality data from the manufacturing floor.
Declining prices whether on the spot market or long-term supply agreements are making business conditions very tough for polysilicon producers, regardless of their market size or purity of the material they produce. According to the latest financial results of Dow Corning, its JV subsidiary, Hemlock Semiconductor expects overcapacity in the sector to continue throughout 2012.
AlsoEnergy has developed several new reporting and collaboration enhancements to its cloud-based ‘PowerTrack’ Energy Management Services software. The newest features allow developers and investors in solar energy systems to create performance models and compare operation between sites and models to quickly detect underperforming components and generate better system returns.
Delayed fourth quarter and full-year results at LDK Solar show the full extent of the challenges facing the integrated PV manufacturer. Having already revised downwards its fourth quarter figures, the company missed revenue guidance and guided first quarter revenue to levels not seen since the second quarter of 2009. Loss from operations for the fourth quarter of fiscal 2011 was US$531.4 million on the back of heavy write downs across the company, leading to a net loss of US$588.7 million. Revenue reached US$2.15 billion in 2011, compared to US$2.5 billion in 2010.
As part of plans to increase hyperpure polysilicon production to meet customer demand, Wacker has officially started volume production at its latest plant in Nünchritz, Germany. Wacker said it had invested €900 million in the facilities, creating more than 500 new jobs. The 15,000MT polysilicon plant should reach full capacity within the next few weeks, Wacker said.
Poor demand for silver paste, primarily used in solar cell production, was highlighted by Ferro management as a key reason for lower quarterly earnings at Ferro Corporation. The company reported net sales of US$466 million for the three-month period ended March 31, 2012, compared with net sales of US$573 million in the first quarter of 2011.
DuPont Microcircuit Materials (MCM) has introduced ‘DuPont Solamet PV416’ photovoltaic metallization paste used to raise the efficiency of thin film photovoltaic cells. The front-side silver paste material has the capability to be processed at temperatures below 140°C, and is designed to provide improved contact resistance, conductivity, adhesion and fine line resolution when printed on Transparent Conductive Oxides (TCOs). The new paste has been claimed to have boosted CIGS thin-film manufacturer, Midsummer AB’s cell efficiencies by as much as 0.5%.
