Abstract

Due to depletion of petroleum, global is seeking for renewable energy to replace the conventional energy. In this study, plastic solar cell was developed by using bis-chalcone (1,4-bis[2-(2-hydroxybenzoyl)vinyl]benzene) as a dye. Bis-chalcone was successfully synthesized by base-catalytic Claisen-Schmidt condensation between 2-hydroxyacetophenone and terephthalaldehyde. The synthesized bis-chalcone was characterized using FTIR and NMR spectroscopy. After that, bis-chalcones were coated on spin coated and hand coated TiO2 which show 3.601 x 10-3 % and 2.439 x 10-3 % of efficiency respectively. Besides, CuS was successfully coated on plastic substrate by using chemical bath deposition and the resistance per cm square of plastics substrate showed 74.6, 31.1 and 12.5 Ω cm-2 when 0.01, 0.05 and 0.10 M of precursors were used respectively. Apart from that, plastics substrate solar cells were fabricated based on 0.01, 0.05 and 0.10 M of concentration which showed 1.503 x 10-3, 6.269 x 10-4 and 1.575 x 10-3 % of efficiency respectively. It is found that the 0.10 M against the theoretical hypothesis, which caused by a few factors included the improvement of plastics substrate conductivity, the properties of CuS and thermal barrier of bis-chalcone compound.
