SOLKRAFT INNOVATIONS AS

Solkraft Cool Module
 The Solkraft Cool Module is a high efficiency solar panel with integrated passive cooling system. The cool module is a 160Wp or 220Wp solar panel that can perform optimally at high temperatures.
Heat Losses
As the sun heats up an ordinary silicon cell module during the day, the cell voltage drops and the power output is dramatically reduced. Research shows an average ""temperature coefficient loss"" in the power output of -0.5%/°C for all modules with silicon cells. To solve this heat-loss problem, Solkraft has developed a passive cooling system which significantly reduces the cell operating temperature.
Cooling Fins
The unique design of the patented Solkraft Cool Module transports heat from the cells to the module backside where an aluminum fin heatsink disperses the heat through radiation and convective air flow. Local air movements will further enhance the heat dissipation from the module. The passive cooling counteracts the voltage reduction caused by rising temperature and increases the power output with 10% to 15% in warm climates.
The Solkraft Cool Module is a frameless module with integrated aluminum fins. The module has a low NOCT and thus a longer life time due to the lower operating temperatures. The module has a higher rigidity due to the aluminum fins firmly attached to the module.

Solkraft was established in 2005 with the aim to become one of the leading solar companies offering innovative products and high quality services to the global photovoltaic industry. With headquater in Oslo, Norway, and branch offices in Italy, Greece & Spain, Solkraft counts on experienced engineers, researchers, project managers, solar energy experts and business development managers who evaluate and develop professional projects and investments in solar energy.  Solkraft develops large-scale photovoltaic plant projects in Eurpean countries with high IRR potential, i.e. with high irradiation and profitable governmental incentives. We are always in search of new projects and partners for the development of large scale photovoltaic projects across Europe. Solkraft´s innovation division has so far successfully developed professional products for the photovoltaic industry market. The first products, launched in the summer of 2007, have been the Solkraft aluminium mounting structures for both roof and ground mounted projects. Solkraft has further developed and patented the first photovoltaic panels with a passive cooling system, the "Solkraft Cool Module". The system is designated to cool down the cells in the modules, and then improve the energy production.

STR GmbH

CGSim 9.02
The CGSim (Crystal Growth Simulator) package is specialized software for simulation and optimization of Czochralski (Cz), Encapsulated Czochralski (LEC, VCz, HPLEC), and various modifications of Bridgman crystal growth, including DSS for solar silicon. CGSim is rather unique tool as it successfully implements simultaneous, coupled modeling of the governing phenomena, which is generally hard to achieve in modeling of growth from the melt. Implemented is a wide range of models including quasi-steady and fully unsteady, 2D axi-symmetrical and fully 3D, with all of the suggested models thoroughly verified using extensive experimental data.
Due to it’s advanced modeling capabilities, CGSim allows the user to get precise information on temperature and heat flux distributions in the furnace, crystallization front geometry and evolution in time, control of single crystal growth (to avoid polycrystal), crystal twisting and generation of macrodislocations, melt, and gas convection coupled along interfaces, magnetic fields (DC, AC, traveling) to control melt flow, point defects in Cz Si and thermo-elastic stresses.
Providing an insight into the above physical processes, CGSim helps the user to solve engineering problems quickly and at low cost. It is particularly effective for design and composition of a crystal growth system, optimization of heater power history and balance between heaters to achieve better crystallization front dynamics, as well as optimization of crystal and crucible rotation rates, crucible position and design, species transport.
In casting of multi-crystalline silicon ingots for solar cells, 3D unsteady analysis of melt convection in a squared mould, coupled with the calculation of the crystallization front shape allows us to predict crystallization front evolution during casting of silicon ingots and flow characteristics in the melt, that affect the quality of the multi-crystal, in particular, the dislocation density in crystal grains, growth shape of grains, the content and uniformity of impurities in a multi-silicon crystal.

PolySim
PolySim is a powerful simulation tool for design and optimization of polycrystalline silicon deposition from chlorosilanes by Siemens process. PolySim is largely oriented to engineers and researchers, and does not require expertise in modeling. Simple and convenient user interface for the problem specification, solution control, and visualization of the results, works in ""engineer-friendly"" terms similar to those used in real reactor operation, which makes getting familiar with the software a matter of several hours.
Unique built-in chemical and thermal models are results of over a decade of experience in modeling Siemens process. All the relevant physical and chemical processes such as turbulent flow, heat and mass transfer, radiative heat exchange, electrical heating of the silicon rods, chlorosilane gas-phase decomposition and surface chemical reactions are accounted for. Importantly, a special model for analysis of the rod surface morphology (“popcorn” formation) was implemented.
PolySim allows the user to find all major process characteristics depending on varying operating conditions and main features of the reactor design, inclulding productivity, energy consumption, silicon conversion, electrical current parameters, gas-phase composition etc. Moreover, PolySim provides means for evaluation and analysis of the conditions non-uniformity and their effect on the growth in the different sections of the rod. Due to the unique approach used to model Siemens process, within a day, the user can analyze multiple trends visualizing the system’s response to the variation of input parameters, which makes PolySim very useful tool from the practical, engineering point of view. PolySim is used now by the leading polysilicon manufacturers and equipment/technology providers in Asia, Europe and USA.

The Linde Group / Linde Nippon Sanso

Generation-F® 3200 Modular High Purity Flourine production for large scale PECVD chamber cleaning
There is currently a high level of attention on the usage of NF3 by the electronics industry because of the very high Global Warming Potential (GWP) of this gas. Linde has been leading the replacement of NF3 with high purity fluorine since 2001, and its innovative technology makes thin film Si PV cell production more efficient and more environmentally friendly at the same time.

NF3 is typically used as a fluorine source for PECVD tool chamber cleaning because it is easy to package and transport. However NF3 has a very high GWP (17,200 x CO2), and it also requires a large amount of energy to release and activate its fluorine. The rapid increase in the use of NF3 due to growth of TFT-LCD display production, highlights the need for a more environmentally friendly cleaning agent for solar, where “energy payback” and reduction of environmental impact are key industry drivers.
Pure fluorine gas not only has zero GWP, but requires less energy to activate, reducing cleaning time and increasing CVD throughput, while reducing cleaning costs by up to 40%. Linde’s unique, patented, technology has been qualified on the major CVD OEM’s equipment and is proven in the demanding service of 300mm wafer and TFT-LCD display manufacture. Linde is pleased to announce the new Generation-F® 3200 module, which produces 40 tpa of electronic grade fluorine, offering even more cost effective cleaning for large scale solar fabs.
Linde has a large installed base of F2 generators with customers, including including Toshiba Matsushita Display, Samsung, and LG. Linde is working with key global solar customers to upgrade their processes to use F2. Modular Generation-F® systems are available immediately to supply any demand from R&D pilot lines up to a Giga-watt solar fab.

The Linde Group is a world leader in industrial gases and engineering with around 50,000 employees working in around 100 countries worldwide. In the clean energy field, Linde is at the forefront of the emerging hydrogen economy, active in CO2 capture & storage, and leading the development of innovative waste-to-energy schemes. In solar energy we supply materials to more than half of the major manufacturers worldwide. Linde’s mission is to develop and apply advanced gas and chemical technologies that help solar cell manufacturers move toward grid parity, while encouraging the adoption of environmentally sustainable manufacturing.
