This review analyzes the predominant pathways that contribute to voltage and current losses due to poor interfaces and also due to non-radiative recombination losses arising from inferior perovskite morphology and its inherent polycrystalline and highly defective nature.
Characterization and Photoelectrochemical Properties of Nanostructured Thin Film Composed of Carbon Nanohorns Covalently Functionalized with Porphyrins
Carbon nanohorns (CNHs) covalently functionalized at the conical tips with porphyrin (H2P) moieties were used to construct photoelectrochemical solar cells. Electrophoretic deposition was applied to…
Supramolecular architectures featuring the antenna effect in solid state DSSCs
Hybrid artificial antenna systems, with implementation of nature's basic concept of self-organization of chromophores, attract vast interest due to their potential application in solar cells. Herein,…
