Universidad de Valencia, Instituto de Ciencia Molecular, C/J. 84 THE PHYSICS OF THE SOLAR CELL Figure 3.2 The radiation spectrum for a black body at 5780K, an AM0 spectrum, and an AM1.5 global spectrum The basic physical principles underlying the operation of solar cells are the subject of this chapter. First of all, there is charge carrier generation (or light pumping): Electrons in the semiconductor (with right band gap E g) absorber are pumped from the valence band (VB) to the conduction band (CB) in the presence of sunlight. • As we know atom consists of protons, neutrons and electrons. The working principle is that we use the energy of photons to get the drift current flowing in the circuit using reversed bias p-n junction diode (p-type and n-type silicon combination). Search inside document . Figure 4 illustrates the basic working principles of a solar cell under sunlight illumination. Many different solar cell technologies are being developed, for various applications (rooftops, solar power plants, satellites, backpacks or clothing, etc.). pv din2. The drawbacks of wafer-based solar cell are low absorption coefficient, expensive, and efficiency of the cell will decrease in high temperature and low light conditions. As the name implies, the mechanism of dye solar cells is based on the photo electrochemical processes. Maximum power point tracking wikipedia. The solar cell technology is the fastest growing power generating technology in the world. 1. These challenges rely on a better understanding of materials and device function principles. Sonia R. Raga. Solar cell working principle ppt. Principle of a Dye Solar Cell. First, a brief review of the fundamental properties of semiconductors is given that includes the energy obtained from the sun, directly into the electrical energy. You are on page 1 of 17.
