Perovskites turn visible light into electricity

Contribution grade

Solar energy · Scoped scientific or research-capability contribution

Reference score25,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Used organolead-halide perovskites as light absorbers in photoelectrochemical solar cells, with a reported conversion efficiency of 3.8% for the iodide-based cell.

Scientific scope

Used organolead-halide perovskites as light absorbers in photoelectrochemical solar cells, with a reported conversion efficiency of 3.8% for the iodide-based cell. Scope limitation: The reported liquid-electrolyte devices differ from later solid-state perovskite cells. Efficiency here does not establish lifetime, scalability or environmental safety.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The reported liquid-electrolyte devices differ from later solid-state perovskite cells. Efficiency here does not establish lifetime, scalability or environmental safety.
