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: A novel non-fullerene electron acceptor (ITIC) that overcomes some of the shortcomings of fullerene acceptors, for example, weak absorption in the visible spectral region and limited energy-level variability, is designed and synthesized.

TL;DR: This review summarizes the developments in small molecular donors, acceptors, and donor-acceptor dyad systems for high-performance multilayer, bulk heterojunction, and single-component OPVs and focuses on correlations of molecular chemical structures with properties, such as absorption, energy levels, charge mobilities, and photovoltaic performances.

TL;DR: A new soluble C(60) derivative, indene-C( 60) bisadduct (ICBA), with a LUMO energy level 0.17 eV higher than that of PCBM is synthesized and indicates that ICBA is an alternative high-performance acceptor and could be widely used in high- performance PSCs.

TL;DR: In this paper, a solution-processable core-shell quantum dots with a CdSe core and a ZnS or CdS/ZnS shell were used as emissive layers in the devices.
