ABSTRACT
During 2008 more than 6140 flashes were performed for research programmes (test centre and other
projects), I-V measurements for third-parties and maintenance measurements (accreditation maintenance).
A total of 458 I-V measurement, 18 determination of the temperature coefficients, 15 I-V
characterization at different irradiances (200, 400, 600 and 800 W/m²), 11 outdoor initial degradation
(30-60 kWh/m²) and 72 I-V determination with multiflash method were performed for third-parties.
In October 2008 the eighth quality audit, for the ISO17025 accreditation maintenance, supervised by
the Swiss Accreditation Service, was successfully passed. The accreditation of the I-V measurements
at different irradiances has been postponed in order to conform the laboratory to the new version
(2008) of the IEC 60904-3 standard. In particular, a new procedure for the irradiance uniformity verification
with two special reference modules and electronics have been designed.
The spectrale response (SR) measurement with automate filter positioning and data acquisition will
be implemented with the new Pasan IIIB sun simulator. A solution, in collaboration with two industrial
partner, consisting in a composition of two CCD spectroradiometers sensitive in ranges 200-1100nm
and 900-1700nm respectively, was selected for the monitoring of the flash spectrum of the sun simulator
In 2008 a new 15 months test cycle (no.11) began. Thirteen different module types were chosen, in
an attempt to include the greater part of available technologies: 4 mc-Si (one with EWT backcontact),
4 sc-Si, 1 HIT (new version), 1 a-Si/a-Si tandem module, 1 a-Si/µc-Si (micromorph) and 2 CIS.
In test cycle 11 the power at the purchase of crystalline silicon technologies (including HIT) was on
average -2.6% lower with respect to Pn but ranging from +0.5% to -10.5%. In 8 of 27 cases power at
purchase was outside production tolerance.
In order to built the test stand for outdoor measurements comparison of the ER for industry, 60pcs of
the new MPPT3000 have been produced.
