An asymmetric wide-bandgap acceptor simultaneously enabling highly efficient single-junction and tandem organic solar cells

Jianqiu Wang et al.

Summary: Ternary and tandem strategies were used to improve the photovoltaic performance of organic solar cells (OSCs). A nonfullerene acceptor named AITC was synthesized and showed good complementary absorption spectrum and miscibility with another acceptor BTP-eC9. The large dipole moment of AITC enhanced the molecular packing in the blend films, improving the photoconductivity and reducing charge recombination in ternary OSCs.

Polymerized Small-Molecule Acceptor as an Interface Modulator to Increase the Performance of All-Small-Molecule Solar Cells

Ziqi Zhang et al.

Summary: The study introduces a polymerized small-molecule acceptor (PJ1) as an interface modulator to optimize the morphology of all-small-molecule organic solar cells (ASM-OSCs) and improve power conversion efficiency. Adding a small amount of PJ1 effectively condenses the morphology, enhances crystallinity, and decreases domain sizes in ASM-OSCs, ultimately leading to accelerated hole transfer and enhanced charge transport.

Understanding, quantifying, and controlling the molecular ordering of semiconducting polymers: from novices to experts and amorphous to perfect crystals

Zhengxing Peng et al.

Summary: The molecular ordering in semiconducting polymers plays a critical role in device performance. The article emphasizes the importance of quantifying molecular ordering and introduces consistent terminology for describing crystallinity, semi-crystallinity, and paracrystallinity. By combining X-ray scattering and calorimetry, a deeper understanding of molecular ordering can be achieved, leading to the classification of polymers based on quantitative analysis of disorder parameters and thermal transitions. Challenges in designing perfect polymer crystals are outlined, along with a proposed molecular grafting approach akin to epitaxy in classic semiconductor thin film growth.

Combining chlorination and sulfuration strategies for high-performance all-small-molecule organic solar cells

Ruimin Zhou et al.

Summary: In this study, three small-molecule donors based on DTBDT unit were designed and synthesized, with chlorinated or/and sulfurated substitutions, along with a non-fullerene acceptor IDIC-4Cl. By combining chlorination and sulfuration strategies, energy levels, molar extinction coefficients, and crystallinities of donors can be effectively altered, with ZR1-S-Cl showing the best performance. The corresponding all-small-molecule organic solar cells achieved a high power conversion efficiency of 12.05% with IDIC-4Cl as an acceptor.

Solvent Annealing Enables 15.39% Efficiency All-Small-Molecule Solar Cells through Improved Molecule Interconnection and Reduced Non-Radiative Loss

Jinfeng Ge et al.

Summary: The study found that solvent annealing with solvents of good solubility is more beneficial for molecular migration and crystallization than thermal annealing, leading to improved efficiency and performance of solar cells. CS2 solvent is better at optimizing donor domain size, improving molecular interconnection, reducing trap states, and decreasing non-radiative recombination. CS2 solvent treatment also helps enhance overall solar cell performance by reducing non-radiative recombination and improving efficiency.
