Perovskite solar cells are the best candidate for solving the problem that you pointed out. The best perovskite/silicon tandem cells in the laboratory have 33% efficiency, and the theoretical limit for this type of cell is 43%.
Do you know if there is any (even theoretical) work to solve the lifetime issue? Perovskites degrade in sunlight (order of months) making it seem unlikely they would ever be useful outside the lab.
