Degradation effects in sc-Si PV modules subjected to natural and induced ageing after several years of field operation [PDF]

, 2012
This paper presents ageing effects observed in sc-Si PV modules operating in field conditions for 18 and over 22 years. The effects of both natural ageing processes and induced ageing by external agents, causing partial or total shading of cells for a ...

New organic matter degradation proxies: Valid in lake systems? [PDF]

, 2004
We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...

A practical degradation based method to predict long-term moisture incursion and colour change in high power LEDs [PDF]

, 2018
The effect of relative humidity on LEDs and how the moisture incursion is associated to the color shift is studied. This paper proposes a different approach to describe the lumen degradation of LEDs due to the long-term effects of humidity.
