Solar Cells Testers

Photo Emission Tech can provide a turn-key integrated Solar Simulator and I-V Measurement System for cell testing. The advantage of a cell tester is that all that needs to be done to test a cell is to load the cell, make electrical probes contact and press “Measure” icon on the I-V Measurement System software. The software will automatically open the Solar Simulator shutter, perform the test and close the shutter after the test is complete.

Any of the Solar Simulator models listed herein can be integrated with any of the I-V Measurement Systems. We can also provide custom cell platen, usually at no extra charge.

Solar Simulation Systems

also known as: Sun Simulator, Simulator Solar, Solar Equipment, Full Spectrum Solution

Photo Emission Tech., Inc. designs, manufacures and markets various illumination areas and wattages of class A Solar Simulators also known as sun simulators that meets ASTM E927 (Japanese Standard JIS C8912 and European Standard IEC 60904-9). The six (6) models of solar simulators marketed by PET provide illumination areas of from 50mmx50mm through 300mmx300mm.

These solar simulator products simulate natural sun light in a variety of conditions, such as those in space or at sea level by providing the user the full spectrum light. PET’s solar simulators are covered by two years factory warranty. There are two versions of each model available. One version has a Micro-Processor based controller which allows the user to digitally control the entire operations of the solar simulator through a controller. The other version of each model has an Electro-Mechanical Control panel.

These solar simulators can be used for checking light-sensitive devices such as solar (photovoltaic) cell performance. These solar simulators can also be used to test and classify solar cells prior to assembly into solar panels. The other applications of these solar simulators are photochemistry for testing exposure to sun light, photobiology research of animals, plants, cells studies, material degradation research, semiconductor testing, phototoxicity studies, and sun light exposure testing and of color fastness and material stability for textile, plastics and paints.

Solar Simulators (Steady State for Cell Testing)

  1. Illumination area from 50mm x 50mm to 400mm x 400mm.
  2. Meets Class A requirements of ASTM E927, JIS C 8912-1989 and IEC 904 standards.
  3. Closest spectral match to the solar spectra.
  4. AM1.5G, AM1G and AM0 filters available.
  5. Built-in light feedback and control system.
  6. Microprocessor based (allows remote trouble shooting via internet connection) or Electro-Mechanical control for Solar Simulators.
  7. All six (6) various PET’s class AAA Solar Simulators offer external X-Y-Z axis feature, whereas the user can adjust the lamp while it is ON for optimum light intensity and uniformity. Since the focal point of lamp shifts as the lamp ages, by periodically adjusting the lamp, the uniformity can be maintained.
  8. All PET’s six (6) various Solar Simulator models are vertical (straight) system, unlike Folded systems offered by other manufacturers that use two reflective mirrors, which causes a loss of 10% to 20% light intensity, PET’s Solar Simulators save energy in the long run.
  9. All models of Solar Simulators and Cell Tester have small footprint.
  10. A two (2) warranty of all parts and lobar for all Solar Simulator and Cell Tester products.

Low Concentration Photo-Voltaic (LCPV) & High Concentration Photo-Voltaic (HCPV) Cell Testing

Testing of LCPV Cells require Solar Simulators that have intensity concentration of 2-10 suns (2,000-10,000 w/m² or 200-1,000 mw/m²). Testing of HCPV Cells require Solar Simulators that have intensity concentration of ≥200 suns (≥200,000 w/m² or ≥20,000 mw/m²). These Solar Simulators deploy concentrating optics consisting of Fresnel lenses that concentrate Solar Simulator output to intensities that match the LCPV or HCPV Cell testing requirements. These LCPV or HCPV Solar Simulators are very useful for applications such as concentrated PV cell testing, accelerated photo-degradation studies and materials testing.

Reference Cells

Reference cells are most commonly used for measuring and setting the intensity of solar simulators for one sun (or other user desired) intensity condition. They can also be used (with supporting equipment) to measure the temporal stability and/or non-uniformity of the light beam of solar simulator.

Surface Quality Monitors

PET also manufactures and markets non-destructive, non-contact surface contamination and thin film detection models and automated systems (Surface Quality Monitoring System) capable of detecting thin layer contamination, thin films and coating down to the Angstrom level. These systems represent a major breakthrough by providing, for the first time, a quantitative measure of surface cleanliness. As surface cleanliness verification instruments, in a part cleaning environment, these products are capable of validating the cleaning quality of all the part cleaning equipment available in the market.

Any of SQM model series is capable of verifying metal contamination; monitoring absence/presence of organic and/or inorganic on virtually on surfaces of all metals. They are, price/performance, the most sufficient product available for testing surface of metals for surface cleanliness. These systems operate in an ambient environment, require no sample preparation or deposit of any agents on the surface. In any parts cleaning environment where the quality and efficiency of part cleaning equipment for removal of surface contamination is highly desired, these systems provide a scientific solution by quantitatively measuring the surface cleanliness. The SQM series has the sensitivity and operational simplicity required to provide fast and cost effective surface evaluation for all metals.
