Daniel Corzo and coauthors replace the solvents for fabrication of organic solar cells and printed organic electronics. Normally, researchers fabricate these devices using aromatic solvents that contain chlorine, known for their severe acute toxicity, causing cancer, and to induce birth defects. Friendlier alternative solvents are hard to use because they tend to reduce the performance of organic printed electronics. D. Corzo introduced the Hansen Solubility framework to screen over 100 k compounds, thus finding that some terpenoids can do the job. These compounds are extracted from plants or recombinant bioreactors as a byproduct of the photosynthesis from CO2. Their safe nature allows their usage as food and cosmetic additives. This is a big step forward towards making safer organic electronics that can be incorporated as part or a circular carbon economy.
