Main Technical Index: Spectral Level: Over Class BBA Effective Irradiation: 2000×1350mm (W×D) or more Irradiance range: 600~1100W/m2 (full lamps) Irradiance resolution: 1W/m2 (200W/m2 at low irradiance performance test by using neutral filters or metallicscreen) Spectral calibration range: 400~1100nm or 300~900nm Testing temperature: 20~60°C±2°C Irradiance and temperature control model: PLC programmable controller & PC control Irradiance measure: by standard cell I-V measuremen: Isc, Voc, Pm, Imp, Vmp, FF, η, Rs, Rp Automatically generating and storing I-V-P curve Xenon lamps matrix is arranged, optimization xenon lamps lighting fixtures angles adjustable.
Automatic non-uniformity measurement system (see right): mechanical transmission system program control, along the X-Y axis horizontal - longitudinal reciprocating scanning, data acquisition and processing. Scanning time can be set. Measurement point more than 64 (IEC 60904-10). automatic alarm when more than 5%.
Shading plate for hot-spot endurance test: ① Crystalline silicon module Can satisfy the 0 ~ 100% within 5% increasing or decreasing. ② Thin-film module 1~5 pieces cell shaded plates horizontal transmission (see right) Ordinal sequence covering 1~5 pcs cells, according to current find Imp×99%, determine shaded plates number. Electric control displacement shaded plates to suitable current. Adjust the shaded plates to suitable current. Data processing system: current automatic collection & analysis
