“…Other than Pt(II), researchers have also investigated the PV performance of Ru(III), Hg(II), etc. based di-, oligo-, and poly-ynes. − The introduction of a metal ion in an organic framework is likely to show synergistic effect on the PV performance, mainly through the intermixing of orbitals and the delocalization of excitons. A metal ion also provides redox-active sites that generate species for charge transport and the auxiliary ligand imparts solubility that helps in the device fabrication .…”

A new A−π−D−π−A small molecule, denoted as MV72, has been designed and synthesized. The molecule comprises a Zn−porphyrin central donor unit and dicyanovinylene-substituted rhodanine (RhCN) endcapping acceptor units linked by bisthienylenevinylene groups as π-conjugated bridges. The optical and electrochemical properties of MV72 have been investigated as an electron donor for solution-processed organic solar cells (OSCs), and the results were compared to those of MV71, which consists of the same molecular backbone but with different rhodanine end-capping acceptor units. The effects of the end-capping terminal units on the absorption spectra, molecular crystallinity, frontier molecular energy levels, charge transport properties, morphology of active layers, and photovoltaic performance have been investigated. The OSCs based on optimized active layers of MV71/PC 71 BM and MV72/PC 71 BM (donor and acceptor weight ratios and solvent vapor annealing) deliver overall power conversion efficiencies (PCEs) of 7.61% and a remarkable 8.80%, respectively. MV72/PC 71 BM showed impressively low energy loss, with a value as low as 0.57 eV; accordingly, a high open-voltage (V OC ) of 0.88 V was achieved. The low energy loss in the MV72-based OSCs is related to the increased dipole moment change for MV72, which in turn results in low exciton binding energy.

Organometallic complexes (OMCs) consisting of organic and metal active moieties have shown immense potential for application in solar cells. The diverse structure, rich porosity, and unique charge centers of OMCs enable them to be functional in solar cells. In this review, we introduced four types of OMCs, such as crown organometallic complexes, β-diketone metal complexes, cyclometallic complexes, and main chain metal-containing polymers, providing an in-depth analysis of the structure-performance relationship. OMCs could serve as active or interlayer materials in a variety of solar cell systems such as organic solar cells, perovskite solar cells, and dye-sensitized solar cells, especially some metals to improve the photoelectric performance of the device as dopants. In the end, perspectives on the opportunities and challenges of OMCs are given.
