    Chemical Analyzing in Photovoltaics for the Solar Power Industry

    In the earlier days, the chemistry involved in solar cell manufacturing was relatively simple, using commodity chemicals. With cell efficiencies continuously on the rise and new cell concepts slowly being introduced with increased speed of processing, precise chemical concentration control is becoming crucial to obtain consistency and more cost-effective manufacturing of solar panels. This is possible by monitoring on-line the etching bath composition, a small but genuine step forward in your competitive advantage.

  • TESTS ON THE FIELD FOR PV PLANTS

    There is no legislation to control of the proper functioning of pyranometers used to measure solar radiation installed in the PV field. The control can be effectively carried out with portable instruments suitable to avoid uninstalling pyranometers set in areas normally inaccessible as placed at the side of panels. A quick test on the field assesses whether a good maintenance is sufficient to obtain a reliable measurement of the solar radiation or if it is necessary to send radiation sensors to the manufacturer for a control. In order to make a test on the field and verify the proper operation of a photovoltaic system, Delta Ohm provides a set of tools that allow an easy and flexible use.

  • Water treatment research for microelectronics industry

    As devices get smaller and the fabrication plants get larger, the purity of the water required for ultrapure water systems increases. In terms of water reuse, the industry has relatively conservative attitudes towards recycling water for ultrapure water applications, but wastewater is treated and reused for cooling and other less critical purposes. Besides semiconductors, two other silicon-based sectors of the microelectronics industry need large volumes of highly pure water: flat panel displays (FPD) and photovoltaics (PV). Although, both sectors are in the process of maturing we anticipate that the increasing complexity of FPD and PV devices will create demand for even higher purity water.
