そもそもDSSC（色素増感太陽電池）とは？

色素が光を吸収して電子を動かし、その電子を酸化物半導体（例：TiO₂）に注入して電気を取り出すタイプの太陽電池です。
近年は「色素（分子設計）」「電極（触媒）」「電解質（イオン輸送）」の3点を工夫して、効率と耐久性を高める研究が盛んです。

What is a DSSC?

A dye‑sensitized solar cell (DSSC) generates electricity by letting a dye absorb light and inject electrons into a semiconductor (often TiO₂).
Current research improves performance by engineering (1) dyes, (2) electrodes/catalysts, and (3) electrolytes/ion transport, while suppressing recombination and enhancing stability.
