In this study, we investigated the effect of annealing time and morphology of ZnO nanorods on the conversion efficiency of hybrid solar cell. ZnO nanorods were synthesized by two-step electrochemically steady stream method. The result showed the uniform growth of nanorods which have a good orientation in demonstrating the hexagonal structure with an average diameter from 30nm to 50nm and average length from 200nm to 250nm. P3HT : PCBM (1:1) conductive polymer blend was also fabricated by spin coating method at 400 rpm and incubated during 10 minutes, 20 minutes, 30 minutes and 60 minutes in nitrogen environment at 1300C. UV-Vis spectrashowed the high photon absorption in the visible light wavelengths with three characteristic peaks at of 515nm, 555nm and 610 nm. With the annealing time of 30 minutes, the highest absorption was reached with the increasing crystallization ofP3HT: PCBM film and thereby the conversion efficiency of the cell was enhanced. Especially, the presence of ZnO nanorods in the system using and without using PEDOT: PSS has showed significantly the enhancement of conversion efficiency of solar cells as compared to the system cell using ZnO film. And conversion efficiency of our device has increased from 0.92 % to 1.23 % (for system without PEDOT: PSS) and from 1.38 % to 1.43 % (for system with PEDOT : PSS layer).

Surface Reflectivity

The surface reflectivity of a material will vary as light passes through interfaces with different refractive indices. Therefore, the optical loss and reflection of an optical-electronic component can be reduced by fabricating nanostructures on its surface. In the case of a solar cell, the presence of nanostructures can deliver many different advantages, such as decreasing the surface reflectivity, enhancing the light trapping, and increasing the efficiency of the carrier collection by providing a shorter diffusion distance for the photogenerated minority carriers. In this study, an approximately 50-nm thick seed layer was first prepared using spin coating. Zinc oxide nanorods (ZnO-NRs) were then grown using a chemical solution method (CSM). The ZnO-NRs were approximately 2 μm in height and 100 nm in diameter. After applying them to amorphous silicon (a-Si:H) solar cells, the short-circuit current density increased from 8.03 to 9.24 mA/cm2, and the photovoltaic conversion efficiency increased by 11.24%.

Thermal Method

A single hybrid solar cell (SHSC) which consist of zinc oxide (ZnO) micro-rod and Poly (3-dodecylthiophene)(P3DDT) materials with nature dye from Melastomamalabathricum fruit (Mm) were fabricated to determine it electrical properties and power conversion efficiency (PCE). The ZnO microrod was growth by thermal method. P3DT was synthesis by oxidation polymerization method. Nature dye was extracted from Mm fruit in purplecolor.The fabrication of a SHSC started with growth ZnO microrodon the Indium Tin Oxide (ITO) in thin filmform, followed with P3DT layers and finally layered with Mm in 5 layers and 10 layers respectively.The SHSC wascharacterized the electrical conductivity and PCE also compared under dark condition and various light intensity. The conductivity of the samples is increase within the increment of light intensity and the efficiency of SHSC increase within the increment of layer of Mm. The highest electrical conductivity was for 10 layers of dye which is 2.678 + 0.002 Scm-1. The power conversion efficiency (PCE) of the ITO/ZnO/P3DDT/10 layers dye achieved was the highest which is 0.0011% under radiation of 200 Wm-2 intensity of light. As a conclusion, it can say that the amount of Mm can affect the performance of hybrid solar cell, where the dye is increased, the electrical conductivity and the PCE also increase. Thus, the Mm is a good dye and can be potential to apply in the solar cell.

Pandanus Amaryllifolius

Solar energy is one in all few sources to renewable power and it is considerably critical in our each day lifestyles usage thus resulted to ensure the practicality and usefulness of the devices which regularly used to capture and manipulate solar energy. In this work, studies the effect of conjugated chlorophyll (iCHLO) on power conversion efficiency with relation of iCHLO where optical and electrical properties were investigated. These hybrid solar cells consist of combination of organic (Poly (3, 4-ethylenedioxythiophene): poly (styrenesulfonate) and iCHLO) and inorganic (Titanium Dioxide, TiO2) materials. These hybrid solar cells were fabricated bilayer of ITO/TiO2/PEDOT: PSS/iCHLO/Al. Chlorophyll compound (CHLO) was extracted from the Pandanus amaryllifolius leaves. CHLO undergoes conjugate process by oxidation polymerization using Ferric Chloride (FeCl3) as catalyst. Different percentage of FeCl3 was varied by 5%, 10% and 15% of CHLO molecular weight. Result shows that UV-Vis absorption spectra of CHLO was absorbed in the range of 400 nm – 600 nm (CHLO-PA) and 240 nm - 360 nm (iCHLO-PA). The highest power conversion efficiency (PCE) was obtained at 1.33% and electrical conductivity is 0.135 Scm1 for ITO/TiO2/PEDOT: PSS/iCHLO-PA 10% hybrid solar cell.
