Abstract

Topography and geographical conditions in Indonesia are very supportive in the effort to use solar energy as a producer of electrical energy. In this research, Dye Sensitized Solar Cell (DSSC) was fabricated using the doctor blading deposition method for coating TiO2 onto the substrate. The research focused on the effect of varying TiO2 thickness. TiO2 as an electron jumping pathway and binders for dye molecules, dye to absorb photons which will help generate electricity. the iodide / triiodide redox pair as electrolyte, and carbon as the counter electrode on the DSSC. TiO2, organic dyes, electrolytes, and counter electrodes are arranged and combined with a layered structure as a donor-acceptor layer. In testing the output power measurement using the Internet of Things, where testing cells at a thickness of 292 micrometers using a 7 watt LED lamp produces the maximum power reaches 4429.8 x 10-9 W.

Abstract

This research presents a low-cost sensor for measuring liquid levels using plastic optical fibers (POF). The sensor reduces the scattering-based optical losses in the fiber, which increase linearly with the liquid height. A U-bent fiber probe and photodetector are used to detect the change in optical intensity. The U-bent probe serves as a test probe for measuring the liquid level. The voltage response difference of the photodetector provides liquid level measurement. This study demonstrates the sensor's responsiveness to liquid level fluctuations above 55 cm at varying temperatures. Sensitivity levels of 1.4 and 3.3 mV/mm were achieved for water level fluctuations below and above 45 cm, respectively. Furthermore, the sensor demonstrated consistently stable responsiveness over multiple cycles.
