Summary: In this study, aromatic rubrene was used to modify the Si surface to improve the junction quality of PEDOT:PSS/Si hybrid solar cells. The interaction of rubrene with Si dangling bonds reduced the binding energies and increased the work function of the PEDOT:PSS film, resulting in a stronger inversion layer and higher efficiency for the solar cells. The power conversion efficiency with rubrene was found to be significantly higher compared to cells without this modification.

Summary: Poly(3,4-ethylenedioxythiophene) (PEDOT):polystyrenesulfonate (PSS)/Si hybrid heterojunction solar cells (HHSCs) were fabricated using a solution-based synthesis method, combining the advantages of PEDOT:PSS and crystalline silicon. The optimized PEDOT:PSS-F4TCNQ hole transport layer (HTL) resulted in organic-silicon solar cells with a Jsc of 33.33 mA/cm2 and an eta of 13.23%. Addition of the electron-accepting dopant (F4TCNQ) increased the conductivity of the HTL films, leading to improved crystallinity and fewer defects. Furthermore, a one-step combination of F4TCNQ with a silane coupling agent (vinyltrimethoxysilane, VTMO) improved the textured device, achieving an efficiency of 14.46% and a Jsc of 33.88 mA/cm2. This study provides an alternative and easy way to develop organic-inorganic hybrid applications with excellent optoelectronic properties and enhances the understanding of organic semiconductors.

Summary: With the introduction of dopant-free carrier-selective contact, Si-based heterojunction solar cells can reduce production costs while maintaining high efficiency. Low-temperature solution processing using inorganic metal oxide semiconductor material ZnO has advantages over conventional silicon solar cells. However, research on low-cost and high-efficiency solar cells based on p-type crystalline silicon is relatively rare.

Summary: Good conductivity and transparency in the visible spectrum, along with low processing temperatures and ease of fabrication, make Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) a widely accepted polymer for organic-inorganic hybrid heterojunction solar cells. However, the PSS segregates more at the surfaces of the deposited film, leading to high contact resistivity with metal and silicon. In this report, we explore the effect of spin coating rates on the contact resistivity and performance of PEDOT:PSS/n-Si solar cells, achieving low contact resistivity and improved overall performance with optimized spin speeds.

Summary: The incorporation of a graphene oxide (GO) layer between the Ag electrode and PEDOT:PSS layer in Si/PEDOT:PSS HHSCs leads to the formation of a strong inversion layer near the Si/PEDOT:PSS interface, resulting in the Si/PEDOT:PSS junction converting into a quasi p-n junction. This structure enhances the built-in potential and suppresses carrier recombination at the interface, resulting in a high-efficiency solar cell with improved performance on textured Si substrate.

Summary: The management of reflectivity and parasitic absorption by adjusting the thickness of PEDOT:PSS film can improve light absorption of the active layer, thereby enhancing the performance of solar cells. Additionally, increasing the PEDOT:PSS film thickness can gradually weaken the quasi-Fermi level bending, stabilize hole concentration, and improve carrier separation efficiency to reduce carrier recombination. The power conversion efficiency (PCE) can reach 12.35% through applying the optimized rule obtained from simulation to the experiment, a 30% improvement compared to unoptimized PEDOT:PSS/Si hybrid solar cells.

Summary: The paper demonstrates a new method to extract specific contact resistance from the minority carrier collection region by using the expanded Cox and Strack method. By utilizing technology computer-aided design and a double equivalent circuit model, the method can separate electron and hole current densities, effectively determining the corresponding resistance for both polarities. The effectiveness of this improved method is further validated through experimental examples, establishing a general method for accurately extracting specific contact resistance in DFHJ silicon solar cells.

Summary: In this study, two dimeric acceptor materials, DIBP3F-Se and DIBP3F-S, were synthesized. Theoretical simulation and experimental studies showed that these dimers adopt O-shaped conformations, likely due to intensified intramolecular π-π interactions. PSCs based on DIBP3F-Se achieved a maximum efficiency of 18.09%, outperforming DIBP3F-S-based cells (16.11%) and ranking among the highest efficiencies for OA-based PSCs.
