The photonic's method is used in the study of monocristalline silicon solar cell (N+P). The induced photocurrent in the cell is analyzed with respect to the technological parameters such as the optical absorption coefficient of silicon and the emitter and base thickness. The spatial and frequential variations of the photocurrent of the cell, when the latter is illuminated by a sinusoidal modulated light, allow access to the diffusion length and lifetime of the minority carriers generated in a given region of the cell. In this paper, the physical parameters related to the base region are determined. In addition, this access is shown to be possible only when the total photocurrent of the cell is reduced to the base diffusion photocurrent.

Abstract. Solar energy’s potential as a clean, abundant, and economical energy source can be effectively exploited if it is converted to electricity. Photosynthetic solar cells (PSCs) convert sunlight to electricity by using plant cells via photosynthesis and respiration. These processes can be interrupted to provide a path of lesser resistance for the transfer of protons and electrons in a proton exchange membrane fuel cell system. PSCs require no organic fuel, no active feeding system, and produce carbon-neutral power both day and night. In this article, the mechanisms of photosynthesis that generate electrons and protons in the anode chamber are described and modeled. In addition, the concentrations of various species in the anode and cathode chambers, including plant cells, sugars, reducing agents, and catalysts, are modeled as a function of time and used to simulate the electric potential across the fuel cell. The resulting flow of electrons through the external circuit is described. The influence of non-ideal effects is described and modeled, such as the resistance to the motion of protons, reactants, and products through the electrolyte, which contributes to a voltage drop across the cell. The activation energy required for the chemical reactions also contributes to voltage drop. These dynamics are modeled using differential equations for each species. This model can be used to predict the dynamics of a PSC system under various conditions. Keywords: Cell power, Cell voltage, Microbial fuel cell, Modeling, Photosynthetic solar cell, Solar energy.

Photocatalytic Effect

One of the effective ways of utilizing marine environments is to generate energy, power, and hydrogen via the effect of photocatalysts in the seawater. Since the ocean is vast, we are able to use its large area, but the power generation system must be of low cost and have high durability against both force and corrosion. In order to meet those requirements, this study focuses on the fabrication of a novel marine wet solar cell composed of a titanium dioxide photoanode and a copper oxide photocathode. These electrodes were deposited on type 329J4L stainless steel, which possesses relative durability in marine environments. This study focuses on the characterization of the photocatalytic properties of electrodes in seawater. Low-cost manufacturing processes of screen-printing and vacuum vapor deposition were applied to produce the titanium dioxide and copper oxides electrodes, respectively. We investigated the photopotential of the electrodes, along with the electrochemical properties and cell voltage properties of the cell. X-ray diffraction spectroscopy (XRD) of the copper oxides electrode was analyzed in association with the loss of photocatalytic effect in the copper oxides electrode. Although the conversion efficiency of the wet cell was less than 1%, it showed promising potential for use in marine environments with low-cost production. Electrochemical impedance spectroscopy (EIS) of the cell was also conducted, from which impedance values regarding the electrical properties of electrodes and their interfaces of charge-transfer processes were obtained. This study focuses on the early phase of the marine wet solar cell, which should be further studied for long-term stability and in actual marine environmental applications.
