Summary: In this study, a bithiophene-cored compound (BTR-TPA) was introduced as an interlayer between Sb2S3 and the hole transport layers to passivate the trap states, thereby improving the efficiency of solar cells. The results show that the introduction of this interface layer leads to suitable energy levels, inhibited antimony oxide impurity phase, and lower trap states, significantly enhancing the photoelectric properties of Sb2S3 solar cells.

Summary: Sb2S3 is regarded as a promising absorber layer in solar cells, especially in tandem devices, but the thin-film solar cells based on Sb2S3 are still lagging behind in power conversion efficiency compared to other technologies. Further research and improvement are needed to fully unleash the potential of Sb2S3 in solar technology.

Summary: A general correlation between trap densities and charge transfer dynamics is established in high-efficiency organic photovoltaic blends. The electron transfer rates decrease with increased trap densities, while the hole transfer rates are independent of trap states. The local charges captured by traps induce potential barrier formation, suppressing electron transfer.

Summary: Organic solar cells (OSCs) have shown great promise for powering IoT and off-grid devices under indoor light. However, the performance of indoor devices may be underestimated due to trap-assisted charge recombination caused by differences in incident light. This study demonstrates that regulating the donor-acceptor interfaces is crucial for reducing trap density and improving the performance of indoor OSCs. The results provide novel optimization guidelines for high-performing indoor OSCs.

Summary: This study investigates the photoinduced charge generation process in nonfullerene acceptor (NFA) based organic solar cells (OSCs). The results show that there is dominant ultrafast and lossless Forster resonance energy transfer (FRET) from photoexcited polymer donors to Y6, followed by reverse hole transfer (HT). This two-step process facilitates spectral uniform photocurrent generation and lowers the non-radiative recombination energy loss.

Summary: This review provides an overview of the current understanding of entropy-driven charge separation in organic solar cells, focusing on the investigation of the entropy effect on exciton dissociation mechanism from both theoretical and experimental aspects. It explores factors such as the dimensionality of the organic semiconductor, energy disorder effect, morphology of the active layer, and the nonequilibrium effect, and discusses how they contribute to compensating the Coulomb dissociation barrier for charge transfer exciton separation and charge generation process. This review offers insights into the underlying mechanisms of exciton separation and provides pathways for enhancing the efficiency of organic solar cells.
