Efficient ternary organic solar cell capable of being used as power generation window and power generation window
The invention discloses an efficient ternary organic solar cell capable of being used as a power generation window and the power generation window. The ternary organic solar cell is divided into a semitransparent type and a non-transparent type. Wherein the opaque type comprises a substrate, an anode, an anode modification layer, a ternary active layer, a cathode modification layer and a cathode which are sequentially arranged from bottom to top, the semitransparent type is further provided with an optical turn-back layer on the cathode, and the ternary active layer is composed of a blend film composed of an electron donor and two non-fullerene alloy receptors with similar structures. According to the invention, the BO-4Cl and m-BTP-PhC6 alloy is adopted, so that controllable adjustment of energy level and morphology can be realized, and 18.61% of energy conversion efficiency (PCE) can be realized in an opaque device. Besides, after a corresponding semitransparent organic solar cell adopts means of optimizing the proportion of a donor and an acceptor, adding an optical turn-back layer and the like, the semitransparent organic solar cell obtains the indexes that the efficiency exceeds 11%, the infrared heat insulation coefficient (IRR) is 0.90, the color rendering index (CRI) is 90 and the human eye visible transmission (AVT) is 32%, and the semitransparent organic solar cell has the performance requirement of serving as a visible transparent power generation window.
本发明公开了一种可用作发电窗户的高效三元有机太阳电池和发电窗户，三元有机太阳电池分为半透明型和不透明型。其中，不透明型包括由下至上依次设置的衬底、阳极、阳极修饰层、三元活性层、阴极修饰层和阴极，半透明型还在阴极上设置光学折返层，其中，三元活性层由电子给体和两个结构类似的非富勒烯合金受体组成的共混膜构成。本发明采用BO‑4Cl和m‑BTP‑PhC6合金可实现能级和形貌的可控调节，在不透明器件中实现18.61％的能量转换效率(PCE)。此外，相应的半透明有机太阳能电池在采用给受体比例优化、增加光学折返层等手段后，获得了效率超过11％、红外隔热系数(IRR)0.90、显色指数(CRI)90以及人眼可视透过(AVT)32％的指标，具备了作为可视透明发电窗户的性能要求。
