The “Framing” (local discoloration along cell edges) was induced by a simple sequential accelerated stress test (consisting of hygrothermal- and UV-stressors) applied to the PV modules with high OTR (oxygen transmission rate) backsheet, irrespect

Publikováno v: 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC).
Cu(In,Ga)(S,Se) (CIGS) photovoltaic (PV) mini modules sensitive to positive voltage stress were subjected to positive voltage stress in dark conditions, followed by light soaking. The maximum power output (P max ) of the mini modules decreased under

Application of stress factors in the combinations and sequences as they occur in the natural environment better reproduces failures seen in the field. Further, choice of sample type for testing that best represents the final product is most likely to

Accelerated Outdoor PID Testing of CIGS Modules and Comparison with Indoor PID Tests
Autor: Atsushi Masuda, Shuuji Tokuda, Hajime Shibata, Darshan Schmitz, Kinichi Ogawa, Keiichiro Sakurai, Hiroshi Tomita
Publikováno v: 2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC).
In order to accelerate the PID tests of commercial CIGS modules outdoors, water was regularly sprayed on modules during the PID test. We could increase the leakage current more than 10 times by water spraying. Comparison of leakage current suggests t

Recently there has been increased interest in using thermoplastic encapsulant materials in photovoltaic modules, but concerns have been raised about whether these would be mechanically stable at high temperatures in the field. Recently, this has beco
