Development of earth-abundant CZTSe thin film photovoltaics via co-evaporation method and their applications to flexible solar cells) |
| 초록 |
CZTSSe has attracted intensive attentions as an earth-abundant absorber. Since the initial efficiency of 0.66% was reported, the world rocord of 12.6% was achieved by IBM and DGIST. IBM used a solution process for low cost CZTSSe deposition, while DGIST adopted a sputtering process which is suitable for scale-up production. Both approaches are based on precursor-deposition followed by post-annealing. In term of reduction in fabricating cost, a simplier process could be more desirable. NREL reported ＞9% efficiency using one-step method. However, there are no progresses in device performance. It might be related to high-qaulity film growth. In this work, we focus on how to grow high-quality films using one-step method. It was found that film morphologies significantly depend on substrate temperatures because of volatile nature of Sn-Se compounds. The photovoltaic device with an optimized CZTSe film showed ~6.47%. Details on material and device characterizations would be discussed. |
