Femtosecond Lasers Solve Solar Panels' Recycling Issue

Cars That Think

Manufacturers achieve the seal by laminating a panel’s silicon cells with polymer sheets between glass panes. But the sticky polymer is hard to separate from the silicon cells at the end of a solar panel’s life, making recycling the materials more difficult. This partial recycling wastes the most valuable materials in the modules. “At

New partnership to advance high-temperature PEM fuel cells; focus on heavy-duty applications

Green Car Congress

Traditional PEM fuel cells have a relatively low operating temperature, which makes for a low tolerance to hydrogen fuel impurities and makes waste-heat rejection a challenge for vehicles. Artist’s concept of a heavy-duty vehicle equipped with high-temperature proton exchange membrane (HT-PEM) fuel cells.
