An example of the perovskite layer is CsSnBr3 which has a bandgap of 1.75eV, ideally suited as a top layer on silicon thin-film which has a bandgap of 1.12eV. Such a tandem solar cell is capable in theory of 45% efficiency, though ST has set a more realistic 30% efficiency goal, higher than the best silicon wafer technologies such as PERC, PERL, HIT, HJ cells with 25-26.6% efficiencies. The efficiencies of today's solar cells on the market in general range from 14% - 25%. A cost effective 30% efficient solar cell with a simple design would revolutionize the solar energy industry by dramatically reducing the balance of system (BoS) costs, thereby eliminating the need for fossil fuel generated electricity entirely. Silicon wafer technology based on polycrystalline or monocrystalline silicon, which is 90% of today's market, would become obsolete.
That's hilarious since they're just way too naïve, no kidding.
