Abstract (EN):
For the first time laser assisted sealing using lead-free glass frit was successfully applied for producing a
DSC panel with a total sealed area of 1638 cm2 and active area of 990 cm2
. The panel comprises 90 DSCs
individual glass sealed cells (140 mm 13 mm) arranged in 10 sub-modules (150 mm 150 mm).
Indoor aging of individual sub-modules in dark and at ambient temperature for 100 days showed rather
small decrease of the photocurrent conversion efficiency: 1.23 104 day1
. The DSC panel was tested
under outdoor working conditions during 47 days in summer time (Porto, Portugal), where the average
day illumination level was about 6 kW h m2
. After 47 days of continuous power production the assembled panel kept 86% of the initial efficiency. No leakage of electrolyte or visual defects in the sealed glass
frit were detected. Glass sealed DSCs performed superior stability under 1000 h of ageing in a climatic
chamber when compared to polymer sealed cells. The results show that the laser assisted sealing can
be applied to large area DSC modules.
