Efficient recyclable organic solar cells on cellulose nanocrystal substrates with a conducting polymer top electrode deposited by film-transfer lamination

- Recyclable solar cells on cellulose nanocrystal substrates are fabricated.
- Conducting polymer top electrode is prepared by film-transfer lamination.
- The dry process of top electrode avoids swelling damage to the cellulose substrate.
- Solar cells exhibit a power conversion efficiency of 4.0%.
