Dye-sensitized Solar Cell (DSSC) based on ZnO nanostructures has been fabricated using mangosteen peel extract as dyes the Yonekawa method and Grätzel method. This research synthesized with nanoparticles, nanorods, nanoflower, nanotree morphologies. Two different morphological structures of were mixed ratio 25:75, 50:50, 75:25, performance DSSC was investigated. The dye used in extracted from v...

A simple and low-cost fabrication method of dye-sensitized solar cells (DSSCs) was developed to improve the structure performance photoanode with pressed layer compact TiO2 thin film using spin coating, screen printing, mechanical compression. In this study, four different layers were adopted fabricate photoanodes: a mesoporous nanoparticles (NPs) layer, NPs on film, film. The deposited fluorin...

Dye-sensitized solar cell (DSSC) has a great potential to convert light into electricity. In this article, prototype of DSSC had been successfully fabricated using ZnO:Al thin film and dye from red dragon fruit as working electrode. films were prepared by sol-gel spin coating method with variation post-heating temperatures. The XRD result confirms that all have hexagonal structure crystal sizes...

In this paper, we prepared Titanium Dioxide (TiO2) based dye sensitized solar cells (DSSC). Downscaling of commercial TiO2 powder have been achieved by systematic ball milling carried out using home-made device. Thin films were and samples characterized XRD, SEM, UV-Vis I-V. The main objective work is to prepare (DSSC) N3 study the effect grain size inside photoanode layer on efficiency cell. U...

We introduce high surface area ZnO nanotube photoanodes templated by anodic aluminum oxide for use in dye-sensitized solar cells (DSSCs). Atomic layer deposition is utilized to coat pores conformally, providing a direct path for charge collection over tens of micrometers thickness. Compared to similar ZnO-based devices, ZnO nanotube cells show exceptional photovoltage and fill factors, in addit...

DSSC (Dye Sensitized Solar Cell) uses dye as a sensitizer material which is used an electron donor to TiO2 nanoparticles and electrolyte transport medium. One of the extracts purple spinach moringa leaves photosensitizer chlorophyll extract or anthocyanin. The nature able absorb light function in DSSC. Making Moringa leaf red after being blended, dried ground into powder. Then powder was mixed ...

Systemic sclerosis (SSc) is one of the most devastating autoimmune diseases characterized by vasculopathy and fibrosis that affects both skin internal organs. IFN signature present in blood SSc patients. Polymorphisms regulatory genes IRF-4,5,7,8 STAT4 have been found to be associated with SSc. Despite these evidence, exact role remains poorly understood. We performed single-cell RNA sequencing...
