Summary: Two coumarin-functionalized DPP derivatives, DPP-Cou and Cou-DPP-Cou, were designed, synthesized, and characterized. The absorption range of the symmetrical Cou-DPP-Cou was extended to 750 nm (E(g)(opt) = 1.67 eV), compared to 700 nm (E(g)(opt) = 1.78 eV) for the asymmetric DPP-Cou. The symmetrical conjugates also showed higher thermal stability and achieved higher power conversion efficiencies (PCE) in organic solar cells due to appropriate morphology for faster charge extraction and lower charge recombination.

Summary: Lead halide perovskite and organic solar cells are seen as promising candidates for clean energy applications, but improvements are needed in the near-infrared photon loss and photovoltage deficit. By integrating low-bandgap organic bulk-heterojunction layers into inverted PSCs, high-performance hybrid solar cells can be constructed. These hybrid solar cells demonstrate excellent power conversion efficiency, extended photoresponse, and superior long-term stability compared to single-component PSCs and OSCs. With the highest efficiency reported for flexible solar cells to date, flexible HSCs can be integrated as a power source for wearable sensors, demonstrating real-time temperature monitoring capabilities.

Summary: This study investigates the thermally-induced degradation of organic photovoltaic devices and its effect on their optical properties, photophysics, and morphology. The results show that the degradation limits the open-circuit voltage and fill factor of the devices, while the short-circuit current density is only slightly affected. Energy-resolved electrochemical impedance spectroscopy measurements reveal a higher energy barrier for charge transfer in the degraded samples. Furthermore, the study finds that field-dependent charge generation significantly limits device performance.

Summary: Poly(triarylamine) (PTAA)-wrapped single-walled carbon nanotubes (SWCNTs) served as both an efficient hole-transporting layer and electrode in perovskite solar cells (PSCs). The dopant-free PTAA used in this dual-role SWCNTs electrode resulted in a well-matched energy level, increased hole-transporting mobility, and hydrophobicity, leading to improved efficiency and stability compared to reference standards using LiTFSI-doped Spiro-OMeTAD. This dopant-free PTAA-applied SWCNTs electrode not only enables efficient utilization of SWCNTs electrodes in PSCs, but also reveals the mechanism of interaction between the hole-transporting layer and SWCNTs.

Summary: This paper introduces a graphene-based interfacial layer material, cationic nitrogen-doped graphene (CNG), and evaluates its performance on inverted perovskite solar cells. The device with a CNG interfacial layer achieved a power conversion efficiency of 13.5%, higher than a state-of-the-art reference using bathocuproine interfacial layer. Mechanistic studies showed that the CNG interfacial layer can efficiently collect electrons, improve conductivity, and smooth out the interface contact to enhance the performance of the inverted perovskite solar cells. Furthermore, the unencapsulated CNG-applied device demonstrated good long-term stability, with 96% efficiency retained over 1000 hours in a nitrogen atmosphere at room temperature.
