Single-Junction Organic Solar Cells with 19.17% Efficiency Enabled by Introducing One Asymmetric Guest Acceptor

Rui Sun et al.

Summary: The ternary strategy is an effective approach to achieve high-efficiency OSCs, but the nonradiative voltage loss limits further efficiency improvements. By incorporating an asymmetric guest acceptor BTP-2F2Cl, the OSCs show improved photoluminescence quantum yield, exciton diffusion length, and absorption spectrum, leading to enhanced power conversion efficiency.

Versatile Sequential Casting Processing for Highly Efficient and Stable Binary Organic Photovoltaics

Chengliang He et al.

Summary: This study investigates the advantages of using the sequential casting (SC) method for bulk heterojunction (BHJ)-based organic solar cells (OSCs). It is found that SC processing can achieve better morphology and device performance compared to the widely-used blend casting (BC) method. The observations on phase separation and vertical distribution inspire the proposal of the swelling-intercalation phase-separation model to explain the morphology evolution during SC processing. Moreover, the vertical phase segregation is found to improve device performance through affecting charge transport and collection processes.

The effect of alkyl substitution position of thienyl outer side chains on photovoltaic performance of A-DA′D-A type acceptors

Xiaolei Kong et al.

Summary: The side chain configuration of organic small molecule acceptors (SMAs) has been found to significantly impact their intermolecular interaction and aggregation morphology. In this study, two isomeric A-DA 'D-A type SMAs with thienyl outer side chains were designed and synthesized to investigate the effects of thienyl conjugated outer side chains and the alkyl substitution position on SMA properties. It was found that the beta-substituted m-TEH SMA exhibited stronger intermolecular interaction and higher electron mobility compared to the alpha-substituted o-TEH SMA. Furthermore, the m-TEH blend film with the PBQ6 polymer donor showed more suitable phase separation, enhanced molecular packing, and improved hole and electron mobilities compared to the o-TEH blend film. Organic solar cells based on PBQ6:m-TEH achieved a significantly higher power conversion efficiency (PCE) of 18.51% compared to PBQ6:o-TEH based solar cells. This study demonstrates that m-TEH with 2-ethylhexyl beta-substituted thienyl outer side chains is an excellent high-performance SMA for organic solar cells.
