We theoretically designed four new A-A-D-A-A type electron donors by side-by-side combination of strong electron-withdrawing groups. The electronic structures and optical absorption spectra of donors ...
Solar cells based on organic semiconductors have attracted much attention. The thickness of the active layer of organic solar cells is typically only 100 nm thin, which is about 1000 times thinner tha...
