摘要
以硅太阳能电池为研究对象,利用ANSYS建立三维电池模型,对其温度和结构进行了耦合仿真,模拟分析了未加装铝翅片和加装铝翅片的两种硅太阳能电池的温度和热应力分布。编制Matlab程序,采用迭代法对光热参数进行迭代求解,得到了转换为热量的太阳辐射值作为初始条件。研究结果表明,加装铝翅片的硅太阳能电池取得了较好的散热效果,能降低热应力,提高太阳能电池板的使用寿命。
Taking silicon solar cell as research object, a three-dimensional cell model is established by using ANSYS to carry out a coupling simulation of the temperature field and stress field, which can analyze the temperature distribution and thermal stress distribution of solar cell under the condition with and without aluminum fin. Furthermore, an iterative method Matlab programed gets the sun radiation, which is taken as an initial condition and will be converted into the heat quantity. The results show that the silicon solar cell can achieve better heat dissipation effect and reduced thermal stress under the condition of the cell with aluminum fin, which extends the service life of solar cell.
