Product Description

The LC-LED-AAA-300S LED Solar Simulator is a high-precision photovoltaic testing system developed by Lecheng Intelligent, specifically optimized for perovskite solar cell and module characterization. Unlike conventional LED simulators that rely on direct LED emission, the LC-LED-AAA-300S integrates a complete optical shaping system, delivering highly collimated, uniform, and spectrally accurate sunlight simulation.

The system complies with IEC 60904-9 Edition 3 international standards and achieves an overall A+ rating across spectral match, irradiance uniformity, and temporal stability. With a wide spectral coverage from 350 nm to 1200 nm, it precisely matches the full-band absorption characteristics of perovskite photovoltaic materials, from ultraviolet to near-infrared.

Designed for both laboratory research and pilot-line verification, the LC-LED-AAA-300S supports steady-state long-duration testing (24–1000 h) as well as transient pulse testing (>200 ms), making it an ideal platform for efficiency calibration, device tolerance evaluation, and long-term stability studies of perovskite solar devices.

How long does it take from equipment ordering to official production when cooperating with Locsen?
The overall timeline varies depending on equipment specifications and production line scale. For standalone equipment, standard models require a 45-day manufacturing cycle, with total duration (including shipping and installation) of approximately 60 days. Customized equipment requires an additional 30 days based on technical requirements. For complete line solutions: • 100MW-level production lines require ~4 months for planning, equipment manufacturing, installation, and commissioning • GW-level production lines require ~8 months We provide detailed project schedules with dedicated managers ensuring seamless coordination. Example: A client's 1GW perovskite production line was completed 15 days ahead of schedule through parallel equipment manufacturing and facility construction.
Does Locsen offer suitable equipment and partnership solutions for startup perovskite companies
Locsen offers a "Phased Partnership Program" specifically designed for perovskite startups. For the initial R&D phase, we provide compact pilot-scale equipment (e.g., 10MW laser scribing systems) bundled with essential process packages to facilitate technology validation and product iteration. During scale-up phases, startups qualify for upgrade benefits: • Core modules from pilot equipment can be traded in with value deduction toward production-line machinery • Optional technical collaboration including process development support and experimental data sharing This program has successfully enabled multiple startups to transition smoothly from lab to pilot production while mitigating early-stage investment risks.
Can Locsen's equipment handle perovskite solar cells of varying sizes? What is the maximum supported dimension?
Locsen's laser equipment features exceptional size compatibility, capable of processing perovskite solar cells ranging from 10cm×10cm to 2.4m×1.2m.
