A tolerance factor is usually used to evaluate whether a pseudocubic perovskite structure can be maintained: 51 t = r A + r X 2 (r B + r X), where t is the tolerance factor, r A is the effective radius of the A-site general cation, r B is the effective radius of the B-site metallic cation, and r X is the effective radius of the X-site halide anion. …
"Perovskite cells have the potential to be lightweight compared to silicon, by orders of magnitude," Bawendi says. Perovskites have a higher bandgap than silicon, which means they absorb a different part of the light spectrum and thus can complement silicon cells to provide even greater combined efficiencies.

The world record device efficiency of single-junction solar cells based on organic–inorganic hybrid perovskites has reached 25.5%. Further improvement in device power conversion efficiency (PCE) can be achieved by either optimizing perovskite films or designing novel device structures such as perovskite/Si tandem solar cells.
Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives.
Due to the reduction of the gap between industrial efficiencies of the current silicon cells, and the new perovskite-silicon tandem cells, as well as their improved theoretical efficiency cap of over 35 %, and their partial utilization of current production technologies (utilizing a silicon-based bottom cell), perovskite-silicon …
In a perovskite single crystal without grain boundaries, there are fewer defects. The trap density of the perovskite single crystal (MAPbI 3) was ∼10 10 cm −3, which is 6−7 orders lower than that of the polycrystalline film with the same chemical composition . Thus, the perovskite single crystal holds promise for efficient carrier …
