Abstract Dopant‐free hole transport materials (HTMs) are ideal for highly efficient and stable n‐i‐p perovskite solar cells (PSCs), but most current design strategies tailoring the molecular structures of HTMs limited to single strategy. Herein, four based on dithienothiophenepyrrole (DTTP) core devised through dual‐strategy methods combining conjugate engineering side chain engineering. DTTP‐ThSO with ester alkyl that can form six‐membered ring by S⋅⋅⋅O noncovalent conformation lock...
We demonstrated one-step method to fabricate two different sizes of graphene quantum dots (GQDs) through chemical cutting from oxide (GO), which had many advantages in terms simple process, low cost, and large scale manufacturing with higher production yield comparing the reported methods. Several analytical methods were employed characterize composition morphology resultants. Bright blue luminescent GQDs obtained a produced as high 34.8%.

Colloidal quantum wells (CQWs) have emerged as a promising family of two-dimensional (2D) optoelectronic materials with outstanding properties, including ultranarrow luminescence emission, nearly unity yield, and large extinction coefficient. However, the performance CQWs-based light-emitting diodes (CQW-LEDs) is far from satisfactory, particularly for deep red emissions (≥660 nm). Herein, high efficiency, ultra-low-efficiency roll-off, luminance, extremely saturated CQW-LEDs are reported. A...
The photocatalytic degradation of TiO2 as the best method to solve pollution dye wastewater has been widely studied.

TiO2/MXene composites were synthesized by low temperature hydrothermal reaction using (P25) and MXene nanosheets raw materials for methylene blue (MB) dye. removal rate MB was effectively combination with materials. achieved at a mass ratio (4:1) MXene. composite...
Abstract Perovskite interfaces where defects enrich are pivotal for both device efficiency and stability. Herein, a high‐molecular‐weight polyvinyl pyrrolidone (PVP) is proposed as robust multi‐functional interlayer to engineer the buried interface. Besides well‐known defect passivation, perovskite crystallization intriguingly modulated via formation of hydrogen‐bond‐based polymer‐ammonium intermediates (e.g., PVP‐FA+ or PVP‐MA+, MA FA methylamine formamidine, respectively). The interaction...
