A test platform for reused solar modules was established in Wuhan in order to study the appearance changes, aging problems and degradation rate in electrical properties of the reused modules. The photovoltaic modules were mono-Si modules produced by Siemens in 1996. It was found that there was moisture at the edge of the modules. The aging of tin-coated copper strip was obvious, and there was blackening phenomenon. There were many white spots on the solar cells around the tin-coated strip, and the solar cells turned blue locally. The average annual power attenuation rate of different modules varied greatly, but it was mainly related to the increase of series resistance of modules. The integrated average annual power attenuation of PV modules was about 3.59% during 4 years.
Reversible superwettability on non-coated metallic surfaces has a broad range of engineering applications, yet achieving a rapid reverse of superwettability is still technically challenging on different metals. Here w...

Flexible conductive composites were fabricated using polyester/cotton (T/C) fabric coated with reduced graphene oxide (RGO) via a repeated dipping-drying Graphene oxide (GO) and sodium dithionite reduction process. The resulting reduced graphene oxide / fabrics (T/C-RGO) exhibited electrical conductivity while retaining mechanical flexibility, making them well-suited for serving as the substrate and electrode in electroluminescent devices. Key fabrication parameters, including GO concentration and dipping-drying cycles were optimized to enhance conductivity. The results revealed that increasing the GO concentration and the number of dipping-drying cycles significantly enhanced the RGO loading, improved the electrical conductivity, which enhanced the luminance performance of fabricated electroluminescent devices. Stability evaluations confirmed excellent luminescence retention, bending durability and water resistance, supporting the reliability and practicality of the electroluminescent devices for wearable applications. This work provided a simple, scalable approach to developing flexible, washable conductive fabrics for wearable optoelectronics.
