激光辐照单晶硅电池转换效率的研究

摘要

In order to study the conversion efficiency of monocrystalline silicon solar cell under laser irradiation, a method to calculate the efficiency of ideal solar cells under laser light was put forward based on the method usually used under solar spectrum. Analytical expressions and experimental measurements were used to describe the relation between the conversion efficiency and laser wavelength, incident intensity and ambient temperature, etcetera. Research shows that, under the laser light conversion efficiency will be improved obviously, the maximum conversion efficiency is up to 27. 7%. All of these have certain reference value to the application of laser power transmission.%为了研究激光照射下单晶硅电池的转换效率,在理想电池太阳光照射下极限转换效率研究方法的基础上,提出激光照射下理想电池转换效率的计算方法,并推导出解析表达式,通过计算和实验测量研究了激光波长、激光强度、环境温度等因素对转换效率的影响.结果表明,相对太阳光,单晶硅电池对单色激光的光电转换效率明显提高,最高转换效率可达27.7％.该结果对激光电力传输应用的研究具有一定的参考价值.
