Single‐Crystalline Structure Assisted Revealing the Critical Factors for the Properties of All‐Small‐Molecule Organic Solar Cells

All‐small‐molecule organic solar cells have attracted great interests due to their well‐defined molecular structures and suitability for investigating the relationship between the structure and properties. Herein, two small‐molecule donors (SMDs) based on DTBDT core with chlorine atoms and alkylsily...

The power conversion efficiency (PCE) based on IDIC‐4Cl is higher than that of Y6 systems due to low driving force between the donors and Y6.
