本論文為開發大面積半透明有機太陽能電池 (Semi-transparent large area organic solar cell),首先我們使用銦錫氧化物 (Indium Tin Oxides, ITO)當作陽極和8 nm的銅銀合金當作透明陰極,再使用吸收近紅外光的NTUST-Donor作為主動層的予體材料和C60作為受體混和沉積成主動層,並使用C60/NTUST-Buffer:C60作為介面修飾層和阻擋層。
我們先在有效面積0.04 cm2的元件中測試出最佳有機層厚度,我們使用3 nm單層C60當作介面修飾層,因為增加C60的厚度雖然會增加光電流,但同時也會吸收過量波長450 nm的可見光,因此為了達到更高的平均可見光穿透率 (average visible transmittance, AVT),我們亦優化了NTUST-Buffer:C60的厚度和比例,最終我們優化後的元件結構為ITO/MoO3 (15 nm)/NTUST-Donor:C60 (1:3 30 nm)/C60 (3 nm)/NTUST-Buffer:C60 (2:1 10 nm)/Cu:Ag (8 nm)/WO3 (30 nm)
接著我們將此結構實現於大面積的ITO陽極基板上,製作出具有10 cm2的半透明有機太陽能電池,以玻璃和ALD進行封裝後分別可達到1.07 %和0.76 %的效率,且PMax分別為10.70 mW和7.51 mW。此研究驗證了有機太陽能電池在大面積開發的發展性,也因為半透明和大面積的優勢,使有機太陽能電池可以被更廣泛的使用在各種裝置上。
In this paper, we use Indium Tin Oxides (ITO) as the anode and 8 nm copper-silver alloy as the transparent cathode to develop a semi-transparent large area organic solar cell. Then, we used NTUST-Donor, which absorbs near-infrared light, as the active layer donor material and C60 as the acceptor to mix and deposit the active layer, and used C60/NTUST-Buffer:C60 as the interface modification layer and blocking layer.
We first measured the optimal thickness of the organic layer in a 0.04 cm2 effective area and used a single layer of C60 at 3 nm as the interface modification layer because increasing the thickness of C60 increases the photocurrent but also absorbs excessive wavelengths of visible light at 450 nm. Therefore, in order to achieve higher average visible transmittance (AVT), we also optimized the thickness and ratio of NTUST-Buffer:C60, and the final optimized component structure is ITO/MoO3 (15 nm)/NTUST-Donor:C60 (1:3 30 nm)/C60 (3 nm)/NTUST-Buffer: C60 (2:1 10 nm)/Cu:Ag (8 nm)/WO3 (30 nm)
We then implemented this structure on a large-area ITO anode substrate and fabricated a 10 cm2 translucent organic solar cell with 1.07 % and 0.76 % efficiency and 10.70 mW and 7.51 mW PMax after packaging with glass and ALD, respectively, to verify the development of organic solar cells in large-area applications. The translucent and large-area advantages of organic solar cells allow them to be more widely used in various devices.
