Summary Using AFORS‐HET v2.5 solar cell simulation software, four “p‐i‐n” structures configured as graphene/n‐MoS2/perovskite/p‐cSi/Au (perovskite: MAPbI3, MAPbI3−xClx, MASnI3, and FASnI3; p‐cSi=p‐type crystalline silicon) have been investigated for an efficient solar cell application. In these structures, graphene and 2D n‐type molybdenum disulfide (n‐MoS2) have been used as a front contact and an emitter layer, respectively. By optimizing the various parameters of graphene, n‐MoS2, perovskite materials, and p‐cSi, the highest power conversion efficiency (η) of 25.75% with VOC = 689.8 mV, JSC = 46.35 mA/cm2, and FF = 80.53% have been achieved for graphene/n‐MoS2/MAPbI3−x Clx/p‐cSi/Au structure. Further, to study the effect of the thickness of MAPbI3−x Clx on cell performance, the thickness has been changed from 100 to 20 nm. The maximum efficiency of 26.65% has been obtained at the thickness of 20 nm. This study provides a route for the application of graphene as front contact, n‐MoS2 as an emitter layer in MAPbI3−x/p‐cSi based “p‐i‐n” structure for solar cell application to obtain higher efficiency.

“…In this case, the output efficiency of the solar cell is always maintained at the maximum value (these technologies can increase the efficiency of the solar cells by 30–60%). To address the surface defects problem of conventional silicon heterojunction solar cells, the introduction of a thin intrinsic layer into the two doped layers of the heterojunction (the structure is called a heterojunction with an intrinsic thin layer, and the typical structures are graphene/MoS 2 heterostructure, [ 213 ] crystal silicon heterojunction [ 214–216 ] ) can greatly reduce the surface defects. With a thin intrinsic layer, Panasonic achieved the world's highest photoelectric conversion efficiency (25.6%) of solar cells.…”

Among diverse wearable techniques, insole‐based plantar pressure monitoring systems have surged as a leading technology to monitor patient's chronic disease progression. Such technological feat has been made possible due to the strong correlation between gait and disease status. Hence, insole‐based plantar pressure monitoring techniques are growing rapidly worldwide; with several research institutions and enterprises showing an increased interest in the field. This review intends to first explain the working principles of mainstream insole plantar sensing techniques and design considerations such as sensing material selection and electronics design requirements, and then the state‐of‐the‐art algorithms for plantar pressure distribution reconstruction. Following, this article will discuss disease monitoring applications and the extraction of disease features. Finally, insight regarding common challenges and their potential solutions within the field would be elucidated.

Graphene is one of the most prevailing materials to replace traditional transparent conductive films (TCFs). In order to improve the performance of graphene TCFs, it is proposed to directly deposit graphene on insulating substrates via assisted catalysis of Cu foil to avoid intricate transfer process, and further effectively enhance the optical performance by introducing the close‐packed antireflection array nanostructure. The graphene TCFs grown on bare quartz substrates have sheet resistance of 0.766 kΩ sq−1 and transmittance of 86.83 %. Graphene composite TCFs with transmittance of 95.79 % were obtained by introducing the close‐packed solid/hollow SiO2 nanospheres antireflection array nanostructure. Compared with graphene TCFs, transmittance of graphene composite TCFs increased significantly, while the sheet resistance remained at the same level. This method combining direct synthesis technique with novel antireflection array nanostructure provides a significant design idea to grow transfer‐free graphene with controllable optoelectronic properties and promotes the application and development of the future electronic devices.
