Small steps for electrons—big steps for the future? Ultrafast microscope reveals electron pathways in solar cells

In the search for more efficient and sustainable energy generation methods, a class of materials called metal halide perovskites have shown great promise. In the few years since their discovery, novel solar cells based on these materials have already achieved efficiencies comparable to commercial silicon solar cells. In the search for more efficient and sustainable energy generation methods, a class of materials called metal halide perovskites have shown great promise.
