Project title: Photonics devices under extreme operating conditions

Acronym: PHOENIX

Project duration: January 2017 - June 2018

Contract: 24PED/ 2017

Project budget: 597.613 RON

Financing body: The project is financially supported by Unitatea Executiva pentru Finantarea Invatamantului Superior, a Cercetarii, Dezvoltarii si Inovarii (UEFISCDI)

Contractor : Institutul National pentru Fizica Laserilor, Plasmei si Radiatiei

Project coordinator: Dr. Dan Sporea

Project summary and objectives:

The goal of the PHOENIX project is to develop and test several demonstration models (laboratory measuring setups), and to prepare appropriate procedures in order to provide services for the evaluation of ionizing radiations effects on: (i) organic solar cells (organic photovoltaics - OPV) and (ii) silicon photomultipliers (SiPM), to assess their reliability for possible use in space missions. The developed setups will be used for OPVs and SiPMs off-line testing, these devices being exposed in different sessions to: (i) gamma-ray, (ii) electron beam, (iii) alpha particles, and (iv) protons. Optical, electrical and optoelectronic characteristics will be measured by pre and post irradiation tests, for various irradiation conditions. The project Coordinator will cooperate with partners from The Netherlands and Germany , who are manufactures of such components. In this way the project will contribute, through its results, to Romania's participation to COST Actions: (i) MP1307, Stable Next-Generation Photovoltaics: Unraveling degradation mechanisms of Organic Solar Cells by complementary characterization techniques - StableNextSol and (ii) TD1401, Fast Advanced Scintillator Timing - FAST which gathers communities interested into the subject. Innovative optical and THz spectroscopy methods will be used for the evaluation of radiation induced changes in the investigated devices.
