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 Cell Tester Model CT300

Photo Emission Tech., Inc. produces various illumination areas and wattages of class B Solar Simulators also known as sun simulators that meets ASTM E927 (Japanese Standard JIS C8912 and European Standard IEC 60904-9). The nine (9) models of solar simulators marketed by PET provide illumination areas of from 50mmx50mm through 400mmx400mm.

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. The class B of PET’s solar simulators that are covered by two years factory warranty, are Micro-Processor based systems which allows the user to digitally control the entire operations of the light source through a controller, while recording the obtained data in the host computer through a RS232.

PET is also worldwide distributor of seven (7) models of class A solar Simulators manufactured by Yamashita Denso, Japan’s leading producer of class A sun simulator for the past 25 years.

These solar simulators can be used for checking light-sensitive devices such as solar (photovoltaic) cell performance. These solar equipments 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.

PET also manufactures and markets various models of quality I-V measurement systems to be used in conjunction with its models of solar simulator for measuring the electrical characteristics of solar cells or other semiconductor devices. PET’s I-V Measurement Systems for Cell Testing are capable to test up to 400mm X 400mm area, with optional temperature control, -350° C to 120° C, optional robotic cell handling and sorting. Custom fixtures are also available with Uniformity measurement fixture and software, and temporal stability measurement and software.

These Solar Cells I-V Measurement testers are very high quality products, easy to use, and are reasonably priced. PET’s technical staff gladly would provide information to assist the customer to meet its need of I-V Measurement needs.

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.

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.

PVE300 is a monolithic, turnkey solution for photovoltaic device research in industry and academia, permitting the quick and accurate characterization of photovoltaic devices and materials.

The ISR300, an Integrated Spectro-radiometer is composed of a single TMc300 monochromator with a two–channels transimpedence amplifiers/ADC. Various models with a range <400nm to more than 21μm are available.
