Diffusion engineering of ions and charge carriers for stable efficient perovskite solar cells
Ion migration in perovskite solar cells are known to cause hysteresis and instability. Biet al., report a charge extraction layer based on graphene, fullerenes and carbon quantum dots which suppresses ion diffusion and enhances charge carrier diffusion leading to efficient devices with improved stab...
