Perovskite solar cell

JapanEvidence: high confidenceChecked July 2026

Tsutomu Miyasaka introduced perovskite solar cells, lightweight photovoltaic devices made through solution-based coating rather than conventional crystalline-silicon processing. The Kyoto Prize credits his work with opening new frontiers in high-efficiency conversion, while his university research group records his 2024 Japan Academy Prize for the technology.

01

What Tsutomu did

Introduced solar cells using organo-metal perovskite materials and solution-based coating processes.

02

Why it matters

The Kyoto Prize identifies his perovskite cell concept as a next-generation power-source platform that overturned assumptions about photovoltaics.
