Researchers test laminated bamboo structures for floating PV platforms Chinese researchers tested thin-plate glued laminated bamboo (glubam) assemblies for use in floating PV platforms, assessing their flexural behavior under different plate and bolt configurations. The results show that plate configuration, bolt spacing, bolt diameter, and thickness distribution can significantly affect the structures’ ultimate load capacity.

Peeling back the layers As part of a PV module’s construction, front and rear encapsulants are used to bond solar cells to the front (typically glass) and rear (glass or polymer backsheet) surfaces. When these components degrade, delamination or bubbles can occur, opening new channels for moisture and oxygen ingress, drastically accelerating other failure mechanisms such as cell metallization corrosion.
