A solar photovoltaic (PV) cell, is an electrical device that uses the PV effect to convert light energy into electricity. The application of oyster mushroom dyes in dye sensitized solar cell (DSSC) is a novel strategy to substitute the costly chemical production process with easily extractable, environmentally acceptable dyes. Both dyes of yellow and pink oyster mushrooms were extracted using the same process but dried into powder form using two techniques, warm drying and freeze drying. The characterization was carried out utilizing current-voltage (I-V) characterization for electrical properties, Ultraviolet-Visible (UV-Vis) spectrophotometer for optical properties, Field Emission Scanning Electron Microscopy (FESEM), and Atomic Force Microscopy (AFM) for the structural properties. It was found that freeze-dried pink and yellow oyster mushroom had shown the good properties for DSSC application as it produced energy bandgap which lies within the range of efficient dye sensitizer; 1.7 eV and 2.2 eV, the most uniform distribution of pores and a nearly spherical form in FESEM analysis, and AFM result obtained with the highest root mean square (RMS) roughness value (26.922 and 34.033) with stereoscopic morphologies. The data proved that mushroom dyes can be incorporated in DSSC with the optimization of drying method in the extraction process, dilution of dye and the layer of deposition on the glass substrate. The current density-voltage (J-V) characteristics of fabricated DSSC was characterized using Newport Oriel Sol3A solar simulator under AM 1.5 Sun condition (100 mW/cm, 25 C). From the result obtained by solar simulator, the fabricated FTO/TiO/Pleurotus djamor dye/Pt indicated the V of 0.499 V and J of 0.397 mA/cm.
太阳能光伏(PV)电池是一种利用光伏效应将光能转化为电能的电气装置。平菇染料在染料敏化太阳能电池(DSSC)中的应用是一种新颖的策略,可用易于提取、环境友好的染料替代昂贵的化学生产工艺。黄色和平菇的两种染料均采用相同工艺提取,但使用温热干燥和冷冻干燥两种技术干燥成粉末形式。利用电流-电压(I-V)特性表征电学性能,用紫外-可见(UV-Vis)分光光度计表征光学性能,用场发射扫描电子显微镜(FESEM)和原子力显微镜(AFM)表征结构性能。结果发现,冷冻干燥的粉色和黄色平菇显示出适用于DSSC的良好性能,因为其产生的能带隙在高效染料敏化剂的范围内;1.7电子伏特和2.2电子伏特,在FESEM分析中孔隙分布最均匀且呈近球形,并且AFM结果显示均方根(RMS)粗糙度值最高(26.922和34.033)且具有立体形态。数据证明,通过优化提取过程中的干燥方法、染料稀释以及在玻璃基板上的沉积层,蘑菇染料可用于DSSC。在AM 1.5太阳条件(100毫瓦/平方厘米,25℃)下,使用Newport Oriel Sol3A太阳能模拟器对制备的DSSC的电流密度-电压(J-V)特性进行表征。根据太阳能模拟器获得的结果,制备的FTO/TiO/红平菇染料/Pt的V为0.499伏,J为0.397毫安/平方厘米。
