TL;DR: Three novel solution-processable small molecules, which contain π-bridges with gradient-decreased electron density and end acceptors substituted with various fluorine atoms, exhibit excellent inverted device performance and an average power conversion efficiency of 11.08% are reported.

TL;DR: All-small-molecule ternary solar cells consisting of two compatible small molecules DR3TBDTT (M1) and DR3tBDTT-E (M2) as donors and PC71BM as acceptor are reported, which provides an important strategy to design high-performance ternaries which contains one molecule which performs a preference to appear at the D-A interfaces hence builds cascade energy levels.

TL;DR: It is demonstrated that ternary organic solar cells exhibit great potential for large-scale fabrication and future applications and large-area devices are successfully fabricated using polyethylene terephthalate (PET)/Silver gride or indium tin oxide (ITO)-based transparent flexible substrates.

TL;DR: In this paper, a simple approach to control BHJ morphologies with optimized phase distribution for small molecule: 6,6]-phenyl-C71-butyric acid methyl ester (PC71 BM) blends by enhancing the substrate temperature during the spin-coating process is presented.
