Tools for Improved Use of Photovoltaics

Now available from Ocean Optics is a complete line of optical-sensing systems and components that addresses the needs of the growing market for photovoltaic solar cells – from characterisation of the thin films comprising such cells to measurement of the spectral output of solar simulators. Ocean Optics is the creator of the world’s first miniature fibre optic spectrometer. Its extensive line of low-cost, small-footprint modular spectrometers and accessories can be configured for millions of different UV-Vis-NIR applications. In particular, users can mix and match spectrometers and accessories to monitor photovoltaic thin films used in the manufacture and assembly of solar panels and to measure the spectral output of both the sun and radiant sources such as solar simulators.

For solar cell production, Ocean Optics spectrometers can be configured for thin film thickness measurement and endpoint detection – important quality control parameters that, if managed well, can help manufacturers reduce waste, eliminate off-specification product and increase yield. For many manufacturers, small savings or improvements in processes can drive the difference between being successful versus merely surviving in such a competitive market.

Ocean Optics spectrometers, including the company’s flagship USB4000-series spectrometers and the new Jaz modular sensing suite, are also useful for monitoring the absolute and relative spectral irradiance of both the sun and artificial sunlight sources such as solar simulators. With the former, measurement of solar characteristics – the sun’s spectral output at various wavelengths and under varying conditions – can help solar system installers ‘tune’ (or position) photovoltaic panels most effectively. With solar simulators, the value is in monitoring how reliably the simulators mimic the sun’s light in various environments. Indeed, the promise of simulators is in making it possible to test solar panels and other components inexpensively, so accurate output of such simulators is critical.
