Abstract

The invention discloses an organic solar cell with dynamically regulated transparency and a preparation method and an application thereof. The method includes the following steps: sputtering an electrode material on a substrate to prepare a first electrode layer; applying an organic material to the first electrode layer through spin coating or thermal evaporation to prepare a first transmission layer, spin-coating the first transmission layer with a mixture of organic matter and fullerene derivative to prepare an optically active layer, spin-coating the optically active layer with oxide, and vapor-depositing metal on the oxide to prepare a second electrode; and finally, vapor-depositing semiconductor oxide on the second electrode, and sputtering catalyst on the semiconductor oxide layer toget an organic solar cell with dynamically regulated transparency. When hydrogen is fed in, the optical property of the gasochromic oxide layer changes, which changes the transmittance and transparency of the semitransparent cell device. The organic solar cell of the invention has the characteristic of photovoltaic generation function and dynamically regulated transmittance and transparency, andcan be applied to the fields of intelligent photovoltaic glass and building integration.

Description

technical field [0001] The invention belongs to the technical field of organic solar cells, and more specifically relates to an organic solar cell whose transparency can be dynamically adjusted and its preparation method and application. Background technique [0002] With the depletion of non-renewable resources such as coal, oil and natural gas, new energy, especially solar cells, has become a hot spot of research at home and abroad. In the family of solar cells, organic solar cells (OSCs) have attracted extensive attention due to their advantages of flexibility, light weight, easy preparation, and potential low price, and their highest efficiency has exceeded 11%. Another feature of OSCs is that their absorption spectrum is discontinuous, and it is easy to make semi-transparent battery devices in the visible light band. Based on this property, OSCs can be integrated into glass to prepare photovoltaic glass (Photovoltaic glass, PV-Glass) which not only has photovoltaic pow...
