Gate-Tunable Polarity-Reconfigurable Photovoltaic Response With Dual Linearity in NbS₃/WSe₂ Heterostructures for In-Sensor Image Processing. [PDF]

Adv Sci (Weinh)
An NbS3/WSe2 van der Waals heterostructure realizes a continuously gate‐tunable self‐powered photovoltaic response through interfacial band‐alignment modulation and reversible built‐in electric‐field switching. The short‐circuit photocurrent scales linearly with incident power density, while short‐circuit photoresponsivity varies linearly with gate ...

Optimization the performance of photovoltaic panels using aluminum-oxide nanofluid as cooling fluid at different concentrations and one-pass flow system

Results in Engineering, 2022
The photovoltaic panel's efficiency will drop when the surface temperature rises, that will also have an adverse effect on the panel's performance and lifespan. Therefore, the cooling of the photovoltaic panel will increase the electrical efficiency.
