Abstract
Organic solar cells (OSCs) have gained much attention in the field of organic electronics since it has advantage of physical light weight, easy to fabricate, consumed less production cost, and could be produced in large scale for energy harvesting applications. These types of electronics are promising devices that can be used to tackle today’s energy issue. Bulk hetero junction organic thin film was deposited using spin-coating method. The material used for the deposition of the thin film is the combination of poly (3-hexylthiophene) (P3HT) and [6,6]-phenyl C60-butyric acid methyl ester (PC60BM) that form the interconnection of donor/acceptor component. Deposition was done by spin coating P3HT: PC60BM onto glass substrate in order to form 100nm P3HT: PC60BM active layer. Thermal annealing at three different temperatures was carried out on the samples deposited. The optical characterization of the thin film was investigated using UV-VIS spectrophotometer. The thin film based on P3HT: PC60BM blend film was deposited and annealed at 120°C, 130°C, and 140°C temperature, respectively. The result shows that the film annealed at 140°C has the highest absorption peak at 520nm wavelength in the visible region followed by annealing done at 130°C. This shows that thermal treatment may improve the stability/efficiency of P3HT: PC60BM thin film.
Highlights
Solar energy is a renewable energy source from the sunlight, and has attracted much attention in recent years as one of the most promising ways to tackle today’s energy crises because it is renewable and eco-friendly
Amongst the popular material used for the fabrication of Organic solar cells (OSCs) is the combination of P3HT and PC60BM that form the interconnection of donor/acceptor components so-called bulk heterojunction
Active Layer Sample Solution Preparation 1ml dichlorobenzene (DCB) solvent was added into 15mg of poly (3-hexylthiophene) (P3HT) and to 15mg of [6,6] phenyl C-butyric acid methyl ester (PCBM) all from Sigma Aldrich to form P3HT and PC60BM solutions separately as reported by [16]
Summary
Solar energy is a renewable energy source from the sunlight, and has attracted much attention in recent years as one of the most promising ways to tackle today’s energy crises because it is renewable and eco-friendly. Amongst the popular material used for the fabrication of OSCs is the combination of P3HT and PC60BM that form the interconnection of donor/acceptor components so-called bulk heterojunction This blend system has been widely used for the study of OSCs and it has been reported to have efficiency increase upon the thermal annealing [4,5,6,7,8]. Annealing is a heat treatment, involves heating a material to above its critical temperature, maintain a suitable temperature and cooling It can induce ductility, soften material, relieve internal stresses, refine structure by making it homogeneous and improve cold working properties The thermal treatment has been proven to increase the crystallinity of polymer material performance. Polymer material can be deposited and fabricated at low temperature by spin-coating and printing
