Abstract:
We investigated the change in the cell efficiency resulting from electron beam accelerated irradiation to understand the possibility of using silicon solar cells with nano-surfaces for satellites. The Si solar cells were made of 6″ micro-textured p-type Si wafers. The Si solar cells were fabricated using a standard cell fabrication process, including POCl₃ diffusion, anti-reflection coating layer deposition, and metal contact and co-firing heat treatment. After manufacturing the cell, we irradiated the cell with a low-energy electron beam to determine its effect. We analyzed the changes in the cell resulting from the irradiation with the electron beam by evaluating the photo-reflectance, transmission electron microscopy, electroluminescence and current-voltage curve.

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
Electron Carriers
Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...

Electron Behavior
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...
