TL;DR: In this paper, a ladder-type electron-deficient core-based central fused ring (Dithienothiophen[3.2-b]- pyrrolobenzothiadiazole) with a benzothiadiadiazoles (BT) core was proposed to fine-tune its absorption and electron affinity.

TL;DR: The results show that the introduction of highly crystalline small molecule donors into ternary OSCs is an effective means to enhance the charge transport and thus increase the active layer thickness of ternARY Oscs to make them more suitable for roll-to-roll production than previous thinner devices.

TL;DR: The delocalization of exciton and electron wavefunction due to strong π-π packing of Y6 is the key for the high performance of this state-of-the-art OSC system.

TL;DR: A new n-OS acceptor, Y5, with an electron-deficient-core-based fused structure is designed and synthesized, which exhibits a strong absorption in the 600-900 nm region with an extinction coefficient of 1.24 × 105 cm-1 and an electron mobility of 2.11 × 10-4 cm2 V-1 s-1, which indicates that Y5 is a universal and highly efficient n- OS acceptor for applications in organic solar cells.

TL;DR: In this article, an efficient and highly stable OSC, containing a novel polymer donor and a non-fullerene acceptor system, is reported, which is based on an inverted device structure that utilizes a self-assembled fullerene monolayer (C60-SAM) as the cathode modification layer.
