Solar Simulators & Solar Cell Characterization

Product development in line with emerging solar cell technologies

S o l a r s i m u l a t o r s
LOT-QuantumDesign supply a variety of solar simulators. These light sources provide a uniform,
collimated output beam with a close spectral match to sunlight.

Features:
• Small beam area; 25 mm, 35 mm, 40 mm, 45 x 45 mm, 51 x 51 mm, 80 mm
• Large beam area: 110 x 110 mm, 160 x 160 mm, 210 x 210 mm, 260 x 260 mm
• Class ABA/AAA
• AM1.5G or AM0 filters available

Solar cell characterization
LOT-QuantumDesign, in partnership with ReRa Solutions, can offer a variety of components for solar
cell I-V characterization.

• Silicon/GaAs reference cells LIGHT & LASERS
• Kelvin probes with a range of tips to suit a variety of cell contacts
• User friendly I-V software for measurements of Voc, Isc, Jsc, Impp, Vmpp, FF, efficiency
• Variety of probe stations (low cost, temperature controlled, automated/multiplexed setups)

SpeQuest: A turn-key quantum efficiency (QE) measurement system
The SpeQuest system is suited for all types of cells. Based on monochromatic light sources and
depending on the application, it can be equipped with a halogen lamp or with an additional xenon light
source for measurements in the UV range.
Features:
• 350-1800 nm standard spectral range (can be extended down to 280 nm with dual lamp configuration) 40
• Multi-colour bias light for triple junction cell measurements
• Integrated detection electronics (dual-channel lock-in amplifier, IV converter)
