POSOMAN project is aimed to study the efficiency of the solar cells in interaction with environmental conditions for increase in their intake efficiency and the capacity working in various pollution areas. The study aims to increase the efficiency by designing new materials, addressing preexistent materials, making theoretical models, numerical simulations. Also novel energy storage materials are being considered for optimization in usage of solar panels. A study of solar panels in various environments is necessary for optimization of materials, coating and position in smart grid. A study is also in order for the solar panels to work in space due to the high energy particles.

From the perspective of POSOMAN project, the issues that need to be addressed refer to the impact of long exposure of the solar cells to the environmental conditions. Chemical species in the atmosphere composition and study of aerosols deposition on solar cells for damage threshold estimation are going to be investigated based on RAMAN breakdown spectroscopy for detecting aerosols, organic and inorganic compounds with increased observation on the toxic ones that influence human health. DARLIOES system - the advanced LIDAR, long distance remote laser induced RAMAN and breakdown spectroscopy using an optical telescope and a high-resolution monochromator (Acton SP2750i) coupled to a Princeton Instruments ICCD camera (Roper Scientific PIMAX3- UNIGEN2, 1024 × 1024 pixels, 2 ns minimum gate time) for detecting the formation and dynamics of the airborne plume. For the scattered radiation investigation of the chemical species a laser beam with a continuously variable wavelength (205-700 nm) is used, generated by a High Resolution-UV/Visible-Optical Parametric Oscillator (HR-UV/V-OPO), pumped by the 3rd harmonic of a Q-switched Nd:YAG Laser (Quantel Brilliant EaZy). This instrument is able to capture fast plume airborne image (2ns gate time) and may be used to investigate in real time several chemical compound behavior at a given point of the free atmosphere. Elaboration of a numerical model for aerosols deposition will complete the study using Free Molecular Flow module in COMSOL Multiphysics ver.5.6 software using finite  element analysis.

Flux radiance fluctuation depending on the environmental, seasonal and atmosphere and radiance attenuation are to be investigated using Sun Sky Lunar Multispectral Photometer CE318-T. Media stress effects on the commercial solar cells efficiency is also an item of the study under this project, including High energy particles (HEP) influence/effects on space solar cells efficiency experimental and computational simulated.

Development of new solar cells, improvements of antireflexive and anticorrosive properties of solar cells surfaces and improvements of electrical contact system of solar cells are intended to be performed using PLD (pulsed laser deposition) method. Laser system for Pulsed Laser Deposition (PLD) of different materials, as in figure. A 10 nm pulsed laser beam, 355 nm, 532 nm and 1064 nm wavelength range generated by a system YG 981E/IR-10 (Existing) will be used for laser ablation of different targets to generate thin films deposition as it follows: materials for protection coatings, pigments, electrical contacts.

Numerical simulation based on Finite Element Method in COMSOL Multiphysics ver. 5.6 will assist, anticipate and complete PLD technique used for thin films deposition.

MAIN OBJECTIVES:

ð  Establishment of the opportunity of using solar energy systems and the need to develop new materials and technologies in the context of actual technical status and the regional policy.

ð  Characterization and production of new materials and technics for solar cells and their response to the media stress

ð  Establishment of the technical opportunity and affordability referring to solar energy elements and technology improvement, development and implementing in production in the context of actual policy and with the level of parameters received based on the research of atmospheric composition influence on the solar cells efficiency and lifetime for actual and new solar cells.

REPORT 2023 (link here)

The numerical models developed in COMSOL will contribute to the analysis of thermal and energetic absorption effects under sun radiation as well to the study of materials emissivity. Radiance attenuation due to particulate matter deposited on materials surface was studied with numerical model developed in COMSOL. In addition to the numerical simulation, sun radiation measurements are now available with the new SPN1 Sunshine Pyranometer acquired through the POSOMAN, PD53/2022 project. Thin films fabricated with the PLD technique from biocomposite materials are potential candidates to be included as components in the solar cells structure.
