本研究係以射頻矽甲烷電漿輔助化學氣相沉積系統製作非晶矽薄膜太陽電池。實驗結果顯示當[TMB]/[SiH4]=3時成長的p+層在電池應用獲得Jsc=16.81 mV/cm2、Voc=854 mV、F.F=61.26%,光電轉換效率則為8.79%。
另一方面我們以射頻電漿濺鍍法製作透明導電膜AZO得到最低的薄膜電阻率6.5 × 10-4 Ω∙cm,載子遷移率8.5 cm2/V-s,載子濃度為1.1 × 1021 cm-3。搭配以散射體結構層形成完整具光散射能力的TCO玻璃。於上述TCO玻璃上製作出的單接面非晶矽薄膜太陽電池元件的Jsc=17.1 mV/cm2、Voc=754 mV、F.F=52.2%, =6.75%。相較於在Asahi-U玻璃上元件的表現(Jsc=16 mA/cm2)。本研究所開發出的散射TCO玻璃在元件製作上短路電流提升6.9%,顯示散射層確實具有增加光捕捉的效果。
In this thesis, thin film amorphous silicon (a-Si:H) solar cells were fabricated by radio-frequency plasma-enhanced chemical vapor deposition. The result showed the short-circuit current (Jsc), open-circuit voltage (Voc) and fill factor (F.F.) of the cell were 16.81 mA/cm2, 854 mV and 61.26%, respectively, which corresponds an optoelectronic conversion efficiency ( ) of 8.79% when [TMB]/[SiH4]= 3 for the p layer. Second, Al-doped ZnO (AZO) films prepared by sputtering were deposited on glasses. The lowest resistivity of AZO layer obtained was 6.5 ×10-4 Ω∙cm at a film thickness of 800 nm. Finally, we fabricated a newly developed transparent conductive oxide (TCO) glass characterized by a spherical layer. A trial of a-Si:H thin film solar cell fabrication on this new textured TCO glass showed Jsc=17.1 mA/cm2, Voc=754 mV, F.F.=52.5% and =6.75%. Compared with a reference cell prepared on Asahi-U glass, 6.9% improvement in Jsc was obtained, indicating the effectiveness of the light-scattering of the proposed TCO glass.
