In组分梯度渐变的n-i-p结构InGaN太阳能电池性能研究
n-i-p Type InGaN Solar Cells with Graded In Composition
摘要
Abstract
In order to optimize InGaN solar cell ( SC ) structures and effectively guide the prepara-tion, the properties of n-i-p InGaN SC structures with graded In composition were investigated. Through APSYS simulation software, the performances of p-i-n and n-i-p SC structures with graded In composition were compared. It is found that n-i-p structures don’t have obvious advantage in the device performance over p-i-n ones when In composition of i-InGaN layer is low, which yet presents better performance with higher In composition. When In composition is 0. 62, the SC conversion ef-ficiency reaches 8 . 48%. The further analysis indicates that the polarization electric field in InGaN layer has the same directions with the built-in one in the depletion region for the case of n-i-p SC structures, which is very beneficial for carrier transport. The n-i-p SC structures with graded In composition are proven to be beneficial for high performance InGaN SCs.关键词
