BiLight unveils perovskite curtain at CES 2026
At CES 2026, BiLight Innovations, a Chinese R&D firm specialising in perovskite photovoltaics, unveiled the world's first rollable photovoltaic curtain and a portable flexible photovoltaic panel.
The perovskite-based curtain is 0.1mm thick and weighs under 150g/sq.m, with a bending radius below 10mm, challenging the rigidity of conventional photovoltaic modules. According to the company, it achieves over 18 percent conversion efficiency with exceptional low-light performance.
The curtain mounts on standard curtain rails while generating power from natural or ambient indoor lighting to supply lamps, smart devices, and energy storage systems. It also provides thermal insulation and solar shading.
For outdoor use, BiLight debuted a portable flexible photovoltaic panel to provide on-the-go power. Users simply pull both ends of the scroll-type device to unfurl the compact unit into a full-sized generator.
With a fabric-like thickness that fits easily into a backpack, it is designed to eliminate the bulk of traditional rigid panels, making it a suitable power companion for hiking, camping, and beach excursions.
