dc.descriptionThe effect of Methylammonium Iodide (CH3NH3PbI3) perovskites (MIP) concentration on the performance of perovskites sensitized solar cell (PSC) was studied. Three MIP concentrations, namely 0.2, 0.4, and 1.0 M were prepared. In this study PSC with a sandwich structure of ITO/TiO2/ MIP /electrolyte/ Pt film was fabricated for this purpose. It was found that power conversion efficiency (PCE) increased with the increasing the concentration of MIP, from 0.01 to 0.21 % as the concentration increase from 0.2 to 1.0 M. Photoluminescence (PL) study showed that the increase of the MIP concentration decrease therecombination of carrier in the device. Electrochemical impedance spectroscopy (EIS) analysis also shows that with the increased of MIP concentration results in the decreased of the Rct due to the improvement of the carrier transport in the devices. en-US

  • 2017: 6th Engineering, Science and Technology Conference - Panama (ESTEC 2017) [115]
    The 6th Engineering, Science and Technology Conference (ESTEC 2017) organized by the Universidad Tecnologica de Panama (UTP) is the most relevant conference, engineering-based, of our country. The topics of the conference are focused on areas of interest of Panama and the Latin America region, including: agroindustry, astronomy, bioengineering, education on engineering, energy and environment, ICT engineering, infrastructure and construction, logistics and transportation, manufacturing processes and material science, robotic, automation and artificial intelligence. This year, ESTEC partnered with IEEE Panama Section to ensure the quality of the peer-reviewed process; we received more than 180 full papers from 20 countries and 50% of those were accepted to participate in the conference and will be published in the conference’s proceeding. Furthermore, the conference included technical tours to the Cocoli’s Gate and the Miraflores Visitors Center of The Panama Canal and to the Wind Power Park in Penonome, Panama.
