The appearance of bubbles is usually due to chemical reactions that release gases, which typically appear at back of the module and accumulate in the encapsulant, but may occasionally appear on the front between the glass and the cell [6,68]. Fig. 15 illustrates the Bubble formation affecting the photovoltaic module.
• Bubble formation is one of the cause of delamination, major problems linked to PV module reliability. • Gas chromatography-mass-spectrometry (GC-MS) is used to determine and quantify the VOCs emanating from EVA at 160 C and therefore to understand the origin of the bubbles during the lamination process.

Home » Common problems of photovoltaic backsheet: bubbles, bulging Common problems of photovoltaic backsheet: bubbles, bulging The long-term stability of photovoltaic modules is key to the continuous production of electricity from a photovoltaic system.
As an important part of the PV panel, the backside protects the cells, but there are some common problems during production and later use. Below is a list of common problems with PV backplates that Maysun Solar has compiled for you. 1. Yellowing
