Adding guanidinium thiocyanate to mixed tin-lead perovskites to improve solar cell efficiency

A team of researchers affiliated with several institutions in the U.S. has found a way to improve the efficiency of perovskite-based solar cells—by adding guanidinium thiocyanate to the mix. In their paper published in the journal Science, the group describes their work with perovskite-based solar cells and how well they worked.
