Abstract
Usaha untuk meningkatkan efisiensi yang dihasilkan oleh Dye Sensitized Solar Cell terus dilakukan. Salah satu caranya yaitu dengan mencampurkan berbagai pewarna atau membuat layer pewarna pada DSSC atau yang biasa disebut dengan co-sensitization. Selain itu, variasi fraksi volume TiO2 juga dilaporkan mampu meningkatkan efisiensi. Berdasarkan penelitian sebelumnya, 90% anatase : 10% rutile merupakan fraksi volume TiO2 yang optimum. Penelitian ini menggunakan kulit manggis, bunga jengger ayam, buah bit merah dan kulit pisang mas sebagai pewarna yang masing-masing mengandung pigmen anthocyanin (A), betalanin (B) dan carotenoid (C). Pewarna tersebut dikarakterisasi menggunakan UV-Vis dan menunjukkan absorpsi pada panjang gelombang 400,5 nm dan 440 nm untuk kulit manggis, 387 dan 475 nm untuk bunga jengger ayam, 485 nm untuk buah bit merah serta 420 nm, 440 nm, 475 nm dan 665 nm untuk kulit pisang mas. Dari berbagai pewarna tersebut akan divariasikan dengan susunan single layer maupun multi layer. TiO2 disintesis menggunakan metode co-precipitation. Ukuran partikel yang dihasilkan adalah 20,06 nm untuk anatase and 69,07 nm untuk rutile. DSSC difabrikasi dengan variasi fraksi volume TiO2 100% anatase dan 90% anatase : 10% rutile. Kurva arus-tegangan (I-V) DSSC yang dihasilkan pada sampel dengan pigmen anthocyanin-carotenoid baik susunan single layer maupun multi layer sebesar 0,039% dan 0,047%. Variasi dengan tambahan pigmen betalain hanya menghasilkan efisiensi yang rendah disebabkan oleh cepatnya laju degradasi pewarna.

Efforts to enhance efficiency generated by Dye Sensitized Solar Cell is still continued. One way is by mixing various dye or make layered dye in DSSC which is commonly called by co-sensitization. Besides varying dye, variation in volume fraction of TiO2 also reported to be able to improve the efficiency, based on earlier findings we employed 90:10 anatase-to-rutile volume fraction as the optimum one. This research uses Garcinia mangostana, Celosia cristata, Beta vulgaris rubra and Musa aromatica as sensitizer in which each of them containing anthocyanin pigment (A), betalain pigment (B) and carotenoid pigment (C), respectively. These dyes were characterized by using UV-vis resulting in optimum absorbance at wavelengths of 400,5 nm and 440 nm for Garcinia mangostana, 387 nm and 475 nm for Celosia cristata, 485 nm for Beta vulgaris rubra and 420 nm, 440 nm, 475 nm and 665 nm for Musa aromatica. From the aforementioned, they were varied as single layer, consisting of more than one dyes or multi layer. TiO2 was synthesized using co-precipitation method. The particle size obtained was 20,06 nm and 69,07 nm for anatase and rutile, respectively. DSSCs were fabricated with 100% anatase and 90% anatase : 10% rutile volume fraction of TiO2. The current-voltage (I-V) characteristic of DSSC employing sample with anthocyanin-carotenoid either as single layer or multi layer dyes have efficiencies of 0,039% and 0,047%, respectively. Variation with additional betalain pigment only resulted in low efficiency caused by the rapid rate of dye degradation.
