Concentrating Solar Power

Concentrating Solar Power

Concentrating Solar Power (CSP) plants generate electricity by concentrating sunlight onto a focal point. CSP plants are generally located in desert regions – consequently, the mirrors used to reflect and focus the sunlight get soiled with sand and dust, and thus require regular cleaning. The current method simply uses water and brushes; however, water is a scare and precious resource in such arid terrains.

Plasma Cleaning of the mirrors may offer an alternative, water-free solution.

In collaboration with researchers at Cranfield University, we are developing our Air Plasma technology to explore the characteristics of a novel atmospheric pressure plasma system for the reduction of water use in the cleaning of CSP mirrors.

The Global CSP market was valued at over $3bn in 2016, with growth of 13% anticipated by 2025. The development of an appropriate and effective atmospheric plasma system will be a disruptive and game-changing technology for the CSP market.

With the M-CCMD affixed to a robotic arm, and a CSP mirror to soil and process, we are able to perform experiments using a lab-based setup that accurately recreates how this method of cleaning may occur in situ on a CSP plant. With the air plasma both removing residue and creating a self-cleaning surface, the results are not only fascinating, but hugely promising.

The 4 Quadrants on the result seen here demonstrate clearly and powerfully the benefits an air plasma process has on a sample.

Top Left: Soiled, processed, Top Right: Soiled, unprocessed, Bottom Left: Not soiled, processed, Bottom Right: Not soiled, not processed

→ Successful cleaning of the mirror → A hydrophilic surface has been achieved → A hydrophilic surface = a self-cleaning surface

Our paper "Cleaning Concentrating Solar Power Mirrors Without Water" has been published in American Institute of Physics

      Surface Treatments

      Steel Plate

      Cold Atmospheric can be used to increase the surface energy of a material, a characteristic fantastically demonstrated by this clip of water preferentially sticking to the treated area of this steel plate


      Cold Atmospheric Plasma has a strong and remarkable ability to increase the wettability of a material – this allows us to bond materials that were previously impossible to join

      • Plasma treatment may help to improve bonding for metal plates.
      • Stainless steel treated with plasma was tested by TWI to improve wet etching.
      • Carbon contamination is removed from surface.
      • XPS result shows Carbon contamination on SUS surface is reduced by plasma treatment


      Broad spectrum and with a phyisical mode of action, resistance is unlikely. Gas plasma has proven santistation efficacy for disinfection and hygiene applications. 3 min treatment can reduce 109 order bacterial load. 2 min treatment of biofilm reduces microbial load by 50% on 24H biofilm. No micro-organisms detected after 5min plasma treatment of 24h and 72 h cultivated biofilms


      Adtec first introduced our gas plasma technology to the Max Planck Institute in 2004 leading to a joint development in plasma medicine. The MicroPlaSter plasma medical device was the first device to be used in clinical trials worldwide for infection management of wounds and surgical site infections. With over 9 years of scientific and clinical research, Adtec's microwave powered argon plasma medical device has been proven to be safe for clinical use. The same technology is now used in the Adtec SteriPlas medical device adopted for use in infection management by hospitals in Europe.

      RF Plasma Generation

      When Adtec first started making RF Power products in 1990, our goal and core concept was to be world-leaders in the design and manufacture of Radio Frequency Plasma Generation equipment.

      We wanted to make products that were rugged and reliable – products that the user had full confidence in to deliver consistently, in the toughest of environments. As critical dimensions and process windows shrink, and the cost of down-time grows, it is more important than ever to have RF products that can take the strain the industry demands. This goal remains at the core of everything we do. We are confident that we are continuing to deliver – all RF power products come with a 2 year warranty as standard.

      Adtec RF Products are essential facilitators of plasma processes across Semiconductor, Flat-Panel, Data-Storage, MEMS, Solar, Sputter and Industrial Coatings.

      RF Plasma Generators

      Solid State linear amplified RF power supplies give superior power control and reliability, with less spurious noise. Careful component choice, coupled with our meticulous amplifier reduces strain, greatly increasing the MTBF. The stability of the amplifier gives greater scope to provide low-duty, microsecond pulsed RF, with superb control at outputs as low as 1W.

      Depending on a customer's need the following items can be added:

      • Vp-p/vp sensor
      • Vdc sensor
      • Vdc arc detection
      Communication options that Adtec supply are:

      • Analogue RS-232C
      • Profibus
      • Adtec AMV Control Software


      AC Power on

      Matching unit is idle and waits for RF power from the generator


      RF Power on

      Matching unit's sensor picks up the RF power signal and activates the automatic tuning mode. By adjusting CLOAD and CPHASE it finds the ignition point of the plasma - normally the highest point of VPP throughput to the reactor


      Plasma Ignites

      Matching unit tunes to the lowest reflected power point - normally where network impedance (ZM)+ the reactor impedance (ZC) is 50ohm


      Plasma ignites

      The matching unit monitors the power signals and automatically re-tunes the system when ZC changes


      RF Power off

      Matching unit returns to idling

      Tuning parameters are stored internally on the matching unit and by using the AMV Control Software, parameters can be modified to change the matching speed, start point (via presets), matching range, and many more. For troubleshooting it is also possible to switch the system between manual and automatic setting. The AMV Control Software can be used to monitor the capacitor positions, forward power, reflected power, Vpp and Vdc (depending on customer requests) from the matching unit.
      Presets and monitoring can be done via analogue control/RS232 control/Profibus (depending on customer request) and the AMV Control Software.

      Cold Plasma Technology

      What is Cold Plasma?

      A cold plasma is a plasma that exists in a state of non-equilibrium. In contrast to a hot plasma, the temperature of the electrons is a cold plasma is some two orders of magnitude greater than the temperature of the ions and molecules, whose temperature is roughly ambient. The result is that these plasmas can exist at as low as 30°C! In fact, they are completely safe to touch!

      Cold Plasma Products

      At Adtec, we are passionate about Plasma Technology; specifically non-thermal atmospheric pressure gas microwave powered plasma (gas plasma). This technology was first developed in the Innovation department of our parent company in Japan and we at Adtec Europe are commercializing this technology.

      Over the years, we have been involved in a number of research projects, investigating the merits of Plasma Technology in various industries. Our portfolio consists of two core technologies, designed, developed and manufactured at Adtec Europe. Non-thermal (also called cold plasma) has many different applications including surface treatment, cleaning and antimicrobial treatments. We look forward to collaborating with partners to develop new applications for plasma technology.

      What is Plasma?

      Consider water. When you apply energy to a solid (ice), you get a liquid (water); apply further energy, you get a gas (steam). But what happens if you keep going?

      Continue to apply energy (heat or charge) to a gas, and the matter will eventually became a plasma – hence Plasma’s title as the “4th State of Matter”. Here on Earth, Plasma can be found in the form of lightning, the Northern Lights, and the stuff in fluorescent lamps; in fact, Plasma is a fundamental state of matter, and it is believed that over 99% of the known Universe (think stars!) exists in this state!

      The continued supply of energy used to generate plasma artificially is most often in the form of an electromagnetic field. This causes a breakdown of the atomic shells and electrons disassociate from the nucleus. In addition to unbound negative electrons, there are now, importantly, positive charged ions. Plasma can therefore be considered a charged, or ionized, gaseous state. It is electrically neutral and highly conductive.

      Plasmas are characterized by their electron density and the average electron energy; broadly, we can speak of “hot” and “cold” plasmas.

      The development of Non-Thermal (Cold) Plasma technologies is hugely exciting, and is an area Adtec specialise in. Incredibly, it is possible to generate a plasma that is safe to the human touch!
