Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells
Advanced Functional Materials, EarlyView.Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational

, 1977 This report describes an automated solar tracking system which is adaptable to most solar collectors which require alignment with the sun's radiation. The system uses partially shaded photovoltaic solar cells to produce error signals for both elevation and azimuth tracking with a high degree of accuracy.

Lattice‐Matched 2D Template Enables Efficient Cesium Tin Halide Perovskite Solar Cells
Advanced Materials, EarlyView.Lattice‐matched 2D perovskite PEA2CsSn2I7 templates the out‐of‐plane growth of inorganic 3D γ‐CsSnI3 along the (110) plane, forming highly oriented 2D/3D tin halide perovskite heterostructures. With reduced trap states and mitigated δ‐phase impurities, the CsSnI3‐based solar cells achieve a power conversion efficiency of 15.27% and maintain stable ...
