Abstract: A capacitive flexible tactile sensor based on graded inclined micro-cylindrical structure, includes an upper electrode layer, a lower electrode layer and a dielectric layer between them. The dielectric layer is composed of an upper dielectric layer and a lower dielectric layer. The upper dielectric layer includes an upper dielectric layer base, upper dielectric layer long micro-cylinders and upper dielectric layer short micro-cylinders. The lower dielectric layer includes lower dielectric layer base, lower dielectric layer long micro-cylinder and lower dielectric layer short micro-cylinder. The upper dielectric layer long micro-cylinders and the lower dielectric layer long micro-cylinders are closely bonded, and there is a distance between the upper dielectric layer short micro-cylinder and the lower dielectric layer short micro-cylinder. The sensor structure of the present application is stable, overcomes the viscous effect.

Abstract: A method for diagnosing an internal loss mechanism of a solar cell is provided. The solar cell includes an anode and a cathode. An electron transport layer, an active layer and a hole transport layer are arranged in sequence from top to bottom between the cathode and the anode. The solar cell is modeled through a solar cell multi-physics simulation platform. Current density-voltage (JV) curves respectively of type A, type B, type C and type D are simulated by regulating a bulk defect and a surface defect of the active layer and a voltage scan rate. The solar cell is subjected to forward voltage scan and reverse voltage scan to obtain forward and reverse JV curves. According to the forward and reverse JV curves, whether the JV curve type of the solar cell is the type A, the type B, the type C or the type D is determined.
