Back-contact module technology offers the advantage of lower yield loss, higher power conversion efficiency, and significantly faster manufacturing as compared to conventional H-pattern modules. In this paper we present results of a systematic accelerated ageing study of ECN back-contact metallization wrap through (MWT) modules. A series of fullsize (6×10 cells) MWT modules based on combinations of four different conductive back-sheet foils, two encapsulants, and two electrically conductive adhesives were manufactured and subjected to the damp heat conditions as defined in the IEC61215 edition 2 standard. Modules that combine conductive back-sheet foil with certain types of isolation lacquer (also referred to as inner layer dielectric, ILD) and EVA showed a high failure rate. It appears that a combined effect of moisture and EVA causes a weakening of adhesion strength at Cu/ILD interface and decisively contributes to delamination at Cu/ILD interface. This delamination puts stress on the interconnection and ultimately results in interconnection failure. Removal of ILD significantly improves the stability of MWT modules in damp heat, as up to 2000 hrs of testing only up to 2.4% relative power loss was observed, and also lowers the foil cost.

“…(1) SILICON-BASED Crystalline silicon modules are characterized by two voltage ranges: 40-45 V for open circuit voltage and 32-38 V at the maximum power point (for modules in systems with an operating voltage of 24 V), as well as 20-25 V for open circuit voltage and 15-17 V at the point of maximum power (for modules in systems with an operating voltage of 12 V). Typical efficiency values for modules based on multicrystalline silicon lie in the range of 13-17% [36], and for monocrystalline in the range of 16-19% [37,38].…”

The rapid growth and evolution of solar panel technology have been driven by continuous advancements in materials science. This review paper provides a comprehensive overview of the diverse range of materials employed in modern solar panels, elucidating their roles, properties, and contributions to overall performance. The discussion encompasses both traditional crystalline silicon-based panels and emerging thin-film technologies. A detailed examination of photovoltaic materials, including monocrystalline and polycrystalline silicon as well as alternative materials such as cadmium telluride (CdTe), copper indium gallium selenide (CIGS), and emerging perovskite solar cells, is presented. Furthermore, the impact of transparent conductive materials, encapsulation polymers, and antireflective coatings on solar panel efficiency and durability is explored. The review delves into the synergistic interplay between material properties, manufacturing processes, and environmental considerations. Through a comprehensive survey of materials utilized in modern solar panels, this paper provides insights into the current state of the field, highlighting avenues for future advancements and sustainable solar energy solutions.

This paper discusses the impact of several combinations of encapsulants, conductive adhesives and back-sheet foils on ECN's back-contact modules performance and reliability. Damp-heat (85˚C; 85% R.H) and thermal cycling (-40˚C; +85˚C) tests were performed up to twice as long as described in the IEC-61215 standard, i.e. 2000 hours of damp-heat and 400 thermal cycles. These tests have been identified as the most important tests for this technology. After climatic chamber testing, the modules were analyzed visually and by electro-luminescence imaging.
