Special Issue Information

Dear Colleagues,

This Special Issue will cover the most recent trends in the development of emerging photovoltaic technologies which utilize different types of organic and hybrid materials. A particular focus will be made on the design and advanced characterization of new materials for solar cells, as well as promising strategies for improving device efficiencies and extending their lifetimes. Technological approaches to upscaling flexible organic and perovskite solar cells, enabling their large-scale production using high-throughput roll-to-roll coating and printing techniques and perspectives of their commercialization will be discussed.

You may choose our Joint Special Issue in Organics.

Abstract

Measurements of XPS survey, core levels (N 1s, O 1s, Pb 4f, I 3d), and valence band (VB) spectra of CH₃NH₃PbI₃ (MAPbI₃) hybrid perovskite prepared on different substrates (glass, indium tin oxide (ITO), and TiO₂) aged under different light-soaking conditions at room temperature are presented. The results reveal that the photochemical stability of MAPbI₃ depends on the type of substrate and gradually decreases when glass is replaced by ITO and TiO₂. Also, the degradation upon exposure to visible light is accompanied by the formation of MAI, PbI₂, and Pb⁰ products as shown by XPS core levels spectra. According to XPS O 1s and VB spectra measurements, this degradation process is superimposed on the partial oxidation of lead atoms in ITO/MAPbI₃ and TiO₂/MAPbI₃, for which Pb–O bonds are formed due to the diffusion of the oxygen ions from the substrates. This unexpected interaction leads to additional photochemical degradation. Full article

Abstract

Star-shaped donor-acceptor molecules are full of promise for organic photovoltaics and electronics. However, the effect of the branching core on physicochemical properties, charge transport and photovoltaic performance of such donor-acceptor materials in single-component (SC) and bulk heterojunction (BHJ) organic solar cells has not been thoroughly addressed. This work shows the comprehensive investigation of six star-shaped donor-acceptor molecules with terminal hexyldicyanovinyl blocks linked through 2,2′-bithiophene π-conjugated bridge to different electron-donating cores such as the pristine and fused triphenylamine, tris(2-methoxyphenyl)amine, carbazole- and benzotriindole-based units. Variation of the branching core strongly impacts on such important properties as the solubility, highest occupied molecular orbital energy, optical absorption, phase behavior, molecular packing and also on the charge-carrier mobility. The performance of SC or BHJ organic solar cells are comprehensively studied and compared. The results obtained provide insight on how to predict and fine-tune photovoltaic performance as well as properties of donor-acceptor star-shaped molecules for organic solar cells. Full article
