Summary: Research has found that current matching can be increased for perovskite silicon tandem solar cells by adding a perovskite silicon heterojunction bottom solar cell on top of a planar front/rear side-textured silicon heterojunction bottom solar cell. Optical simulation and planning were used to determine measures for improving the device and maximizing the tandem current density. Variations in the perovskite bandgap and thickness were investigated to achieve current matching between the two subcells. Analysis was also done on limitations such as nonradiative recombination at the perovskite's interfaces. Replacing the hole transport layer PTAA with 2PACz resulted in an increase in the overall certified power conversion efficiency.

Summary: The limited charge transport properties of block copolymers and double-cable conjugated polymers hinder the overall performance of single-component photovoltaic devices. This study investigates the barrier formed between the donor-acceptor covalent bond that hinders electron transport in single-component photovoltaic devices and clarifies the difference in transport mechanisms between single-component and bulk heterojunction devices. The study also demonstrates the exceptional advantages of block copolymer-based devices in terms of charge transport properties, stability to compositional variations, film uniformity, and device reproducibility, highlighting the enormous commercial viability of large-area single-component organic solar cells (SCOSCs).

Summary: A high-performance circularly polarized light detector is fabricated by designing a chiral polymer as a donor, enabling detection from ultraviolet to near-infrared. The detector shows excellent ability to distinguish right-handed and left-handed circularly polarized light, with optimized detectivity, responsivity, and electric current. The dissymmetry in electric current can be increased by an external magnetic field, which is a rare report for chiroptical detectors. The chirality-generated orbital angular momentum is a key factor determining the performance of circularly polarized light detection.

Summary: To solve the corrosion and diffusion issues in perovskite solar cells, a high amorphization ZrNx barrier film is introduced into p-i-n perovskite solar cells. Pattern recognition techniques are employed to quantify the amorphous-crystalline (a-c) interface density, revealing that reducing the a-c interface in the amorphous film leads to dense atom arrangement and uniform distribution of chemical potential, which can retard ion-metal interdiffusion and protect the electrodes from corrosion. The resulting solar cells exhibit improved operational stability, retaining 88% of initial efficiency after continuous maximum power point tracking under 1-Sun illumination at room temperature for 1500 hours.

Summary: Perovskite solar cells have gained significant attention for their rapid efficiency increase and convenient preparation. Among them, wide bandgap perovskites have advantages in tandem solar cell development and are the most promising candidate for commercialization. However, stability issues significantly hinder the further development of wide bandgap perovskites. Due to their ionic nature, wide bandgap perovskites experience severe photo-induced segregation and degradation under illumination. Therefore, we summarize the reasons for the instability of wide bandgap perovskites and discuss strategies for stability improvement. Finally, we provide prospects for the future development of wide bandgap perovskites.
