New understanding of energy losses in emerging light source

The light-emitting electrochemical cell (LEC) can be fabricated in a sustainable and cost-effective way on both rigid and flexible surfaces making it suitable for a broad range of applications, like illumination, health care, and signage. Despite its potential, this technology faces a significant challenge: a decrease in emission efficiency at higher electrical currents, a phenomenon known as "efficiency roll-off."
