Lead-based perovskite solar cells had reached a bottleneck and demonstrated significant power conversion efficiency (PCE) growth matching the performance of traditional polycrystalline silicon solar cells. Lead-containing ...

In the past decade, 2D materials such as graphitic carbon nitride, transition metal dichalcogenides, layered metal oxides and hydroxides, hexagonal boron nitride and MXenes have garnered a great attention with the discovery ...
