Title (EN) POLYMERS WITH BODIPY-BASED BACKBONE FOR SOLAR CELLS
(FR) POLYMÈRES AVEC SQUELETTE À BASE DE BODIPY POUR DES CELLULES SOLAIRES
Abstract:
(EN) The present application discloses the preparation of BODIPY-based backbone polymers for use in solar cell devices. Embodiments provide efficient solution-processed bulk heterojunction ("BHJ") polymer/PCBM solar cells with BODIPY-based backbone polymers (pBodipy and pBodipy-T) as the polymer electron donor. In some embodiments of the present application, solar cells exhibit highly efficient light harvesting of the solar spectrum up to ~1.6eV. CV data suggest these BODIPY-based backbone polymers have an optimal energy level alignment for charge separation in contact with PCBM, and deep HOMO levels that result in the high Voc of 0.8 V and efficiency of about 2%.
(FR) La présente invention concerne la préparation de polymères à squelette à base de BODIPY à utiliser dans des dispositifs de cellules solaires. Des modes de réalisation fournissent des cellules solaires à base de polymères/PCBM à hétérojonction en volume (BHJ) traitées selon une solution efficace avec des polymères à squelette à base de BODIPY (pBodipy et pBodipy-T) en tant que donneurs d'électrons aux polymères. Dans certains modes de réalisation de la présente application, des cellules solaires présentent une capture de lumière extrêmement efficace dans le spectre solaire jusqu'à environ 1,6 eV. Les données CV suggèrent que ces polymères à squelette à base de BODIPY ont un niveau d'alignement d'énergie optimal pour la séparation de charge en contact avec le PCBM, et des niveaux HOMO profonds qui donnent une tension Voc élevée de 0,8 V et un rendement d'environ 2 %.
