| Solar energy is the first human to recognize and take advantage of one of the energy. Since the20th century, with the social and economic development and people’s living standards improve,the demand for energy continues to grow. Solar energy resources with a huge amount of timefor a long time, shine on the earth, the advantages of clean and safe, with great developmentpotential. While solar energy has dispersed, intermittent and instability, low efficiency andhigh cost disadvantage, restricting the increasing use of solar energy, which requires researchdesigned to overcome.The objective for solar cell applications prospects, and therefore Characteristics andapplication of solar cells designed for paper topics, divided into four parts.Part I: solar energy resources.Part II: Principles of solar cells and current market conditions.Part III: Characteristics of the solar cell include: Ante Anfu silicon solar cell test, theopen circuit voltage, short circuit current and the relationship between the light intensitymeasurement, the solar cell output characteristic testing, environmental factors affect theperformance of the solar cell.Part IV: Solar automatic tracking system: Because the position of the sun will changeover time change, or solar power system itself needs to be moved, so the solar power system,solar panels big question is whether the right towards the sun, so solar energy conversion thehighest efficiency. Therefore, the solar tracking system for solar power generation isparticularly important. The paper last solar tracking system as research, design more practicalthree solar tracking system: single-axis stepper, photoelectric comparison method usinglatitude and longitude tracking method. |
