Synthesis and Investigation of Photovoltaic Properties of New Organic Dye in Solar Cells Device

In this paper, we designed and synthesized free-metal dyes based on indoline. The proposed dyes were synthesized from phenothiazine as the starting material by standard reactions. The chemical structure of the synthesized dye was confirmed using FT-IR, 1HNMR and DSC techniques. Spectrophotometric measurements of the organic dyes in acetonitrile and on a TiO2 substrate ...

Add-on for High Throughput Screening in Material Discovery for Organic Electronics: “Tagging” Molecules to Address the Device Considerations

This work reflects the worth of intelligent modeling in controlling the nanostructure morphology in manufacturing organic bulk heterojunction (BHJ) solar cells. It suggests the idea of screening the pool of material design possibilities inspired by machine learning. To fulfill this goal, a set of experimental data on a BHJ solar cell with a donor structure of diketopyrrolopyrrole (DDP) and ...

A Centennial Review of Sub-sonic Transport Aircraft

From Wright Brothers 1903 to present day 2003, aeronautical technology has made a profound progress. This paper demonstrates the outcome of this progress in weight, wing area, and engine thrust in three categories of transport aircraft of short to long range, regional jets, and turbo-prop commuter aircraft. Also the paper includes those aircraft with distinct jump in aeronautical technology. Fe...

Trends of Semiconductor Technology for Total System Solutions

OVERVIEW: Recent progress in electronics technology has been remarkable. Progress in electronics overall has been supported by semiconductor technology with the information equipment field, as typified by multimedia, but one leading example. The semiconductor technology that makes implementation of a system on chip possible has contributed both to higher levels of system performance and also to...

Control over Power Conversion Efficiency of BHJ Solar Cells: Learn more from Less, with Artificial Intelligence

Harvesting the energy from the sun through the bulk heterojunction (BHJ) solar cells need materials with specific electronic characteristics. However, any promising material if cast improperly in cells will end into low or even null power conversion efficiency (PCE). Cell casting optimization is a time/material consumable step in any photovoltaic manufacturing practice. In this study, we sh...
