Summary: Multijunction solar cells can surpass the efficiency limits of single-junction devices. Metal halide perovskite solar cells, in combination with silicon and copper indium gallium selenide (CIGS) or as all-perovskite tandems, have shown promising results. Narrow-gap non-fullerene acceptors have also significantly improved the efficiencies of organic solar cells. In this study, perovskite-organic tandem cells with high efficiency and voltage are demonstrated, utilizing optimized charge extraction layers and an ultrathin metal-like indium oxide layer for interconnection. This milestone work outperforms the best perovskite single junctions and is comparable to perovskite-CIGS and all-perovskite multijunctions.

Summary: This study presents various low-temperature approaches for metallization and interconnection of high-efficiency solar cells, such as silicon heterojunction (SHJ) or perovskite silicon tandems. By using fine line screen printing and Ag-free or reduced interconnection technologies, the potential of these approaches for SHJ and perovskite silicon tandem cells is demonstrated. Furthermore, low temperature or ultra-low-temperature processes are utilized to treat these temperature-sensitive solar cells with reduced energy consumption. The findings also provide a basis for successful module integration of perovskite silicon tandem solar cells with different interconnection technologies.

Summary: Two types of triphenylamine-derived solid-state emissive carbon dots (CDs) are synthesized through solvothermal treatment, exhibiting orange and yellow color. The nonplanar structure and good carrier mobility of the triphenylamine unit effectively inhibit the direct pi-pi stacking and enhance the fluorescence properties of the CDs in aggregation state. Using the CDs as single emissive layer, high-performance orange and green electroluminescent light-emitting diodes (LEDs) are fabricated, achieving high brightness, current efficiency, and low turn-on voltage. This work provides a versatile platform for the construction of novel solid-state emissive CDs with potential applications in photoelectric devices.

Summary: Due to its safety, economy, flexible design, and eco-friendliness, the organic redox flow battery (ORFB) is considered a technology with huge development potential. However, its mass transfer behavior has been a limitation. A novel spindle electrode structure was designed to enhance mass transfer and improve battery performance. Numerical modeling revealed that the spindle electrodes increased discharge voltages by 8% and reduced charge voltage by 5.5%, compared to conventional cuboid electrodes. The average concentration of 2,6-reDHAQ in the spindle electrode was 107% higher, and the uniformity factor was 46% higher than in the cuboid electrode. This study concluded that the spindle electrode can improve the battery performance of ORFB and provide a new design idea beneficial for its industrialization and commercialization.

Summary: In this study, a systematic method is introduced to design semitransparent tandem solar cells (ST-TSCs) and CsPbI2Br/PTB7-Th:IEICO-4F-based perovskite/organic tandem solar cells (P/O-TSCs) with outstanding color-fidelity are successfully developed. A numerical method is established to construct the device structure and evaluate ST-TSCs' color-fidelity and photovoltaic performance. By introducing a PTB7-Th layer on CsPbI2Br, neutral-colored semitransparent P/O-TSCs with balanced efficiency and good color neutrality are achieved. The synergistic effects of the transmittance fluctuation factor and light-absorption selectivity open the path to design and fabricate these high-performance semitransparent solar cells.

Summary: Utilizing bromine-based quasi-2D perovskite is a feasible strategy for achieving efficient and stable blue PeLEDs. The phase distribution is modulated by introducing alkali-salt to reduce the n = 1 phase, and a novel Lewis base is proposed as a passivating agent to decrease defects. As a result, the EQE dramatically improves due to the suppression of severe non-radiative recombination losses. Efficient blue PeLEDs with a peak EQE of 3.82% at 487 nm are obtained.
