En este trabajo se diseñó y estudió teóricamente un conjunto de tres compuestos orgánicos con arquitectura D-π-A, basados en carbazol como donador, un puente π de tiofeno y fenil, y distintos grupos aceptores, con potencial aplicación como sensibilizadores en celdas DSSC. Los colorantes CTC, CTA y CTN se analizaron mediante DFT y TD-DFT con el nivel de cálculo M06/6-31G(d,p). Los espectros UV-Vis mostraron máximos de absorción en 401, 530 y 598 nm, respectivamente, evidenciando un desplazamiento batocrómico asociado al grupo aceptor. El análisis electrónico reveló una alineación energética adecuada con el TiO2 y el electrolito I-/I3-, mientras que las simulaciones de adsorción confirmaron un anclaje estable, destacando CTN con la mayor energía de adsorción (−3.89 eV). En conjunto, los resultados indican que los tres compuestos presentan propiedades ópticas y electrónicas favorables para su uso potencial en DSSC.
