采用AMPS-1D程序模拟分析了前后接触少子复合速率以及吸收层的厚度和少子迁移率对非晶硅/单晶硅异质结太阳电池光伏性能的影响.模拟发现,与太阳电池的前接触少子复合速率相比,背接触少子复合速率对太阳电池光伏性能的影响更为显著.吸收层单晶硅的厚度对太阳电池光伏性能的影响要受到单晶硅隙间缺陷态密度以及背接触少子复合速率的制约.当背接触复合占主要地位时,吸收层越厚电池的转换效率越高;当吸收层隙间缺陷复合占主要地位时,电池的转换效率在某一厚度处达到峰值.吸收层的少子迁移率对太阳电池性能的影响,也要受到背接触少子复合速率的制约.当背接触复合速率较低时,少子迁移率越大,电池的转换效率越高;当背接触复合速率较高时,少子迁移率越小,电池的转换效率越高. 相似文献

The naming game is a model of nonequilibrium dynamics for the self-organized emergence of a language or a communication system. We study a modified version of the minimal naming game in which the speaker selects a word from its inventory with a probability proportional to exp(Rs * α), where Rs is the success ratio of the name and α is a tunable parameter. By investigating the effects of α on the evolutionary processes for both square lattice and scale-free networks, we find that the convergence time decreases with the increasing α on both two networks, which indicates that preferential selection of successful words can accelerate the reaching of consensus. More interestingly, for α 〉 0, we find that the relation between convergence time and α exhibits a power-law form. 相似文献
