Abstract Graphene/silicon (Gr/Si) photodetectors have attracted much attention recently for their simple fabrication and satisfactory performance. However, the responsivity is relatively low compared to other visible detectors. Herein, plasma effects are induced enhance photon absorption by covering random platinum nanoparticles (Pt NPs) on top of devices. Consequently, a stronger built‐in electric field in Gr/Si generated due high work function Pt. Their can reach up 1.68 × 10 7 AW −1 ,...
Considering the evaporation of solvents during fabrication perovskite films, organic ambience will present a significant influence on morphologies and properties films. To clarify this issue, various ambiences N,N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), chlorobenzene (CBZ) are introduced films by two-step sequential deposition method. The results reveal that an ambient CBZ atmosphere is favorable to control nucleation growth CH3NH3PbI3 grains while others negative effect....
Organic–inorganic halide perovskite solar cells have attracted great attention in recent years. But there are still a lot of unresolved issues related to the such as phenomenon anomalous hysteresis characteristics and long-term stability devices. Here, we developed simple three-layered efficient device by replacing commonly employed PCBM electrical transport layer with an ultrathin fulleropyrrolidinium iodide (C60-bis) inverted p-i-n architecture. The devices C60-bis electronic yield average...
Graphene/silicon (Gr/Si) solar cells have triggered considerable interest for their potential in low‐cost and high‐efficiency photovoltaic applications. However, the performance of Gr/Si is still limited by poor Gr conductivity carrier recombination at interface. In this study, a solution‐processable poly(3‐hexylthiophene‐2,5‐diyl) (P3HT) thin film employed as selective interlayer graphene n‐type Si cells, which can increase work function due to photoinduced p‐type doping under light...
