owadays organic dye materials are receiving more interest in solar cell due to improved solution process ability, scalable
synthesis, tunable chemical and physical properties via molecular design and low cost. However, the compatibility and
aggregation of squaraine dye limited broad application. In this study, we designed a system contend of octavinyl-polyhedral
oligomeric silsesquioxane OV-POSS which used to solve these problems. These is the first time designed a novel hybrids large
broad absorption visible to near infrared transient absorption spectroscopy, prepared by OV-POSS with 6-Bromoquanaldine
and squaric acid (semisquaraine (SSQ) squaraine (SQ)) H2 their light properties a broad spectral coverage in a big region from
400 to 800 nm. Our systems were characterized by Fourier Transform Infrared Spectroscopy FTIR, 1HNMR, UV-Vis-Spectra,
Water contact angle images and FE-SEM properties, and when a combination our system dyes with N719 as co-sensitization
in photovoltaic performance using Ti foil-based solar cell DSSC. It showed highest properties a power conversion efficiency
of 7.73%, with a short-circuit current density (Jsc) of 18.48 mA/cm

, an open-circuit voltage (Voc) of 0.73 V and a fill factor
of 46.22% under the AM 1.5G illumination with an intensity of 100 mW/cm

from a solar simulator hence exhibited good
performance in solar cell application.
