Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0024] In the present invention, the donor and the acceptor in the atomic force microscope (AFM) phase diagram are converted into black and white two phases by using the method of black and white image at first, and the obvious donor / acceptor (D / A) contact boundary is obtained, and then by calculating the difference The relative length of the D / A contact boundary of the photosensitive layer of the sample realizes the quantitative characterization of the phase separation degree of the photosensitive layer of the polymer solar cell.
[0025] It should be noted that the present invention relates to a method for characterizing the degree of phase separation of the photosensitive layer of a polymer solar cell, wherein the prepa...
