【摘要】：疊層結(jié)構(gòu)是提高硅基薄膜電池效率和穩(wěn)定性的有效方法,然而子電池電流不匹配使其效率的提升受到限制。為了提高疊層電池的子電池電流匹配度,需選擇合適的中間層材料。通過(guò)硅基薄膜疊層電池的中間層的光學(xué)設(shè)計(jì)和理論計(jì)算,獲得了材料折射率與厚度的匹配關(guān)系:中間層材料折射率n選取范圍為1.59~3.1,中間層厚度d的制備范圍為125/n~175/n nm,最佳厚度d為150/n nm。最優(yōu)中間層材料的折射率和厚度應(yīng)為:n約為1.59,d約為94.3nm,采用這一條件可最大限度地提高硅基薄膜疊層電池的子電池電流匹配度。從疊層電池中間層的光學(xué)特性方面入手為實(shí)驗(yàn)研究提供了設(shè)計(jì)指導(dǎo)。
[Abstract]:Laminated structure is an effective method to improve the efficiency and stability of silicon-based thin film batteries. However, the current mismatch of subbatteries limits the efficiency of silicon-based thin film batteries. In order to improve the current matching of laminated battery, it is necessary to select the appropriate intermediate material. Through the optical design and theoretical calculation of the middle layer of silicon based thin film laminated battery, the matching relationship between the refractive index and thickness of the material is obtained: the refractive index n of the middle layer material is 1.59 鈮，
