New article out in ACS Energy Letters! Using stroboSCAT to image charge transport in two lead-free double halide perovskites, we find that carrier diffusion lengths exceed 1 micron despite shallow trap-limited transport. These diffusion lengths combined with good absorption properties suggest that halide double perovskites are viable candidates to rival the archetypal lead halide perovskites for photovoltaic applications.
