Abstract:
(EN) The present invention relates to a preparation method for a solution processable organic photovoltaic compound using benzothiophene (benzoselenophene) and thiophene (selenophene) as a π bridge, and use thereof, the structural formula of the compound being as represented by formula I. By selecting a suitable organic photoelectric compound of D and A units on the basis of the π bridge, the compound of the present invention has low exciton binding energy and is able to effectively reduce the highest occupied electronic orbital energy level of molecules, thereby making it possible for a high-efficiency material to obtain a high open circuit voltage. As a donor material of an active layer of an organic solar cell, the compound of the present invention has a highest open circuit voltage over 1 V. The compound uses a fluoridized receptor unit as a terminal. The cell energy conversion efficiency of a righted structure of the solar cell exceeds 10%, and the cell energy conversion efficiency of an inverted device structure of the solar cell reaches 11.5% without being subject to any additive or thermal and solvent annealing processing. The compound has important application value.
(FR) La présente invention concerne un procédé de préparation d'un composé photovoltaïque organique pouvant être traité en solution à l'aide de benzothiophène (benzosélénophène) et de thiophène (sélénophène) en tant que pont pi, et son utilisation, la formule structurale du composé étant représentée par la formule I. Par sélection d'un composé photoélectrique organique approprié de D et A unités sur la base du pont pi, le composé de la présente invention présente une faible énergie de liaison d'excitons et est capable de réduire efficacement le niveau le plus élevé d'énergie électronique orbitale de molécules, ce qui permet d'obtenir un matériau à haut rendement pour obtenir une tension de circuit ouvert élevée. En tant que matériau donneur d'une couche active d'une cellule solaire organique, le composé de la présente invention a une tension de circuit ouvert plus élevée que 1 V. Le composé utilise une unité de récepteur fluoré en tant que terminal. Le rendement de conversion d'énergie de cellule d'une structure ordonnée de la cellule solaire dépasse 10 %, et le rendement de conversion d'énergie de cellule d'une structure de dispositif inversé de la cellule solaire atteint 11,5 % sans être soumise à un aucun traitement additif ou thermique et traitement de recuit de solvant. Le composé présente une valeur d'application importante.
