The present disclosure provides an automatic test system for actual stress of a bridge based on DIC technology, where the system includes a camera, a phosphor spraying device, a computer, and a sliding rail; the sliding rail is arranged on both sides of an upper wing of a box-shaped concrete beam; the phosphor spraying device is used to spray phosphor on a web of the box-shaped concrete beam to form speckles of varying light and shade; the camera is slidably connected to the sliding rail through a bracket, and is used to photograph the speckles and transmit a speckle image to the computer; and the computer is used to analyze and process the speckle image taken by the camera and generate a time history diagram of stress.

Automatic test system for actual stress of a bridge based on DIC technology

The present invention discloses a ternary polymer solar cell. A photoactive layer of the ternary polymer solar cell includes two non-fullerene electron acceptors with large planarity. The weight percentage composition of the photoactive layer in the ternary polymer solar cell is: 41.6-50% of polymer electron donor, 0-50% of polymer electron acceptor, and 0-50% of non-fullerene perylene diimide (PDI) electron acceptor. The non-fullerene PDI electron acceptor is added into the photoactive layer to broaden the spectral absorption of the photoactive layer, improve the phase separation of the photoactive layer and inhibit the recombination of bimolecular charges, resulting in more efficient generation and transport of charges, thereby increasing a short-circuit current density of the ternary polymer solar cell device, and finally improving the power conversion efficiency of the ternary polymer solar cell device. Moreover, a new direction is provided for the selection of the all-polymer non-fullerene acceptor.
