A reflective photovoltaic colour filter could boost display efficiency in smartphones and e-readers, according to a new research project.
A team at the University of Michigan have developed a reflective colour filter device by adding organic semiconductor solar cells to an ultra-thin colour filter. This is composed of nano-thin sheets, measuring just 200 nano-metres thick, thinner than traditional filters. These then convert 2% of the display backlight to power, making the display more efficient, reports R&D.
The findings of the study are published in the paper 'Photonic Colour Filters Integrated with Organic Solar Cells for Energy Harvesting'.
