Example Embodiment
[0038] The embodiment of the invention discloses an organic solar cell, including:
[0039] First electrode
[0040] Second electrode
[0041] A photoactive layer between the first electrode and the second electrode;
[0042] The electron transport layer is between the first electrode and the photoactive layer;
[0043] The hole transport layer is between the second electrode and the photoactive layer,
[0044] Wherein, the electron transport layer and / or the hole transport layer are provided with metal nanoparticles.
[0045] The present invention is provided with metal nanoparticles in the electron transport layer and / or hole transport layer. The surface plasmon effect of the metal nanoparticles enhances the absorption of light and increases the photocurrent of the device, thereby significantly improving the performance of the organic solar cell device. Photoelectric conversion efficiency; at the same time, because the metal nanoparticles are located in the electron transport layer and...
