Characterization for next-generation solar cells

Open Instruments delivers high-performance imaging and spectroscopy equipment designed specifically for perovskite, silicon, and perovskite-silicon tandem solar cells

We work alongside top researchers to develop our products, ensuring the specifications meet the demands of cutting-edge research. Three such products, ready for order today, are LUMiKON, EleQuant and AURA.

LUMiKON MAX and LUMiKON MINI are photoluminescence (PL) imaging systems that produce images of key solar cell parameters within seconds. They incorporate the latest algorithms and are the only systems on the market capable of contactlessly imaging spatial variation of the true implied open-circuit voltage. LUMiKON MAX is targeted at R&D on commercial solar cells and is available with multiple optional additions, including EL, IV, and hyperspectral imaging for material uniformity and composition. LUMiKON MINI is a compact glovebox-compatible unit intended for rapid high-throughput screening of new materials.

AURA is a photothermal deflection spectrometer capable of measuring the absorption of thin film samples, with a sensitivity up to 1000x higher than conventional optical absorption spectrometers. This unique property enables researchers to uncover performance-limiting non-radiative defects in their materials, not detectable by luminescence-based methods.

EleQuant measures the absolute photo or electroluminescence quantum yield (PLQY, ELQY) of semiconductor films and devices. It enables users to determine their true radiative efficiency, as well as the area-averaged implied open-circuit voltage. The system is capable of measuring these properties under various environmental (temperature, light) conditions.
