Nanomaterials and halide perovskites - can they really be useful for solar cells?

Both nanomaterials and halide perovskites have generated a tremendous amount of hype in the solar cell research community. Some of this attention is very much deserved, but in both cases there are also serious challenges left to be addressed before commercialization can be considered. This talk will highlight the big challenges remaining for solar cells, point to places where nanomaterials and/or halide perovskites provide some unique characteristics that may be able to address these challenges and end with a prospective on what big questions are left to address.
