Extraction Of Papaya Latex (Carica Papaya) With Dopping Cu As Dye Sentisized Solar Cell (DSSC)

Indonesia is a biodiversity country. Abundance of biological resources may encourage researchers to optimize its use. As an example papaya trees are utilized as raw material for thin films. Sap of papaya latex is doppinged with Cu. This composition is depositioned on top of FTO by spin coating method. The addition of Cu dopping aims to control the rate of crystallinity of the material. This research will add Cu between 10% and 50% solution. Based on FTIR test results, flavonoid compounds might be obtained with O-H group, some aromatic rings C = C and C = O, aliphatic compounds C-H and -CO. Flavonoid compounds are potentially utilized as dye for DSSC. The thickness of dye produced by doping Cu 10% is approximately (0.5-2) μm. Furthermore, dopping Cu from 20% to 40% can produce thickness around 10-50 nm. Meanwhile, the results of the XRD test show an effective Cu between 10% to 40%.

Czts Thin Films

The Cu2ZnSnS4 (CZTS) thin films were fabricated by the direct solution coating method using a novel non-particulate ink. The ink was formulated using ethanol as the solvent and 1,2-diaminopropane as the complex-ing agent. The pure phase kesterite films with good crystallinity, large-sized crystals and excellent electrical properties were prepared by the spin-coating deposition technique using the homogeneous and air-stable ink. It was found that the subsequent pre-treatment temperature had an influence on the film crystallinity and electrical properties. The best film was obtained by pre-treating the spin-coated film at 250 °C, and then post-annealing at 560 °C. The film shows a narrow bandgap of 1.52 eV and excellent electrical properties, with a resistivity of 0.07 Ocm, carrier concentration of 3.0 x 1017 cm-3, and mobility of 4.15 cm2 V-1 s-1. The novel non-particulate ink is promising for printing high quality CZTS thin films as absorber layers of thin film solar cells.
