A transparent MoS(2)-graphene nanosheet (GNS) nanocomposite counter electrode (CE) was incorporated into a Pt-free dye-sensitized solar cell (DSC). The DSC assembled with the transparent MoS(2)-GNS CE therefore exhibited an impressive photovoltaic conversion efficiency of 5.81%, up to 93% of that obtained using the conventional Pt CE (6.24%).

Fabrication of carbon-based perovskite solar cells via the solvent-extraction crystal growth approach attained great device performance and intrinsic enduring stability.

We designed a dimeric porphyrin dye based on an efficient push–pull zinc porphyrin with extended π-conjugation so that the light-harvesting ability exhibits a panchromatic feature covering a broad spectral region from 400 nm to 900 nm.

The Z907-sensitized solar cells attained power conversion efficiencies exceeding 10% with the HDP-ML and HD1-BL film configurations.
