Summary: This work presents the first highly efficient single-crystal cesium tin triiodide (CsSnI3) perovskite nanowire solar cell. The single-crystal CsSnI3 perovskite nanowires possess a perfect lattice structure, low carrier trap density, long carrier lifetime, and excellent carrier mobility, making them a promising candidate for flexible perovskite photovoltaics. By using CsSnI3 single-crystal nanowire in combination with highly conductive wide bandgap semiconductors, an unprecedented efficiency of 11.7% under AM 1.5G illumination is achieved. This study demonstrates the feasibility of tin-based perovskite solar cells and opens up possibilities for powering flexible wearable devices in the future.

Summary: The electrical characteristics of quad-crescent-shaped silicon nanowire solar cells were analyzed numerically to optimize performance, resulting in increased optical absorption and power conversion efficiency. The core-shell junction design showed an improvement of approximately 80% in conversion efficiency due to the high back surface field layer, with minimal impact from nanowire surface recombination compared to the axial junction.

Summary: As the efficiency of perovskite/Si tandem solar cells exceeds the practical limit of single-junction cells, stability becomes crucial for real-world application. Recent studies have shown that potential-induced degradation and partial recovery can occur in PVSK/Si TSCs based on external potential, highlighting the necessity to address previously understudied PID issues for successful commercialization.

Summary: In this study, Ag/Ti/n+/p-Si NWs/MoOx/Ag solar cells were fabricated with a highly luminescent 2D perovskite (C18H35NH3)2SnBr4 applied to the front surface. This 2D perovskite passivates the Si NWs surface and also causes a downshifting and energy-transfer effect, resulting in improved conversion efficiency.

Summary: Through optical simulation, we found that a solar cell with a CZTSe shell has a higher ideal short circuit current value than a CZTS cell; a shell design using both CZTS and CZTSe is proposed to nearly double the maximum ideal current value of the solar cell compared to a planar solar cell; the investigated solar cell still performs well as long as the incident angle does not exceed 60 degrees.

Summary: This study investigates the influence of nanoscale Si pyramid textures on the performance of perovskite/Si tandem solar cells. It is found that excessive texture size leads to non-uniform top-cell formation and reduced performance. However, reducing the texture size within a certain range can suppress reflection and enhance the open-circuit voltage and current of the cell.

Summary: This study introduces a core-shell GaAs/GaInP nanowire solar cell grown by molecular beam epitaxy on a patterned Si substrate, and investigates its optoelectronic properties and limitations. The results show a power conversion efficiency of almost 3.7% and an open-circuit voltage of 0.65 V, which are state-of-the-art values for a nanowire array solar cell on Si. The study also quantifies the quasi-Fermi level splitting in the nanowire array solar cell and provides insights into the main absorption and electrical losses.
