碲化镉是一种很有前途的薄膜太阳能电池光伏材料。然而，传统的SnO2/Poly-CDS/Poly-CdTe器件结构已经使用了30多年，限制了器件性能和重复性的进一步提高。在本文中，我们回顾了NREL的部分研发方法，以了解与传统器件结构相关的问题，并开发几种新材料和一种改进的器件结构来最大限度地减少这些问题。通过采用新的材料和改进的器件结构，我们已经获得了NREL确认的总面积效率为16.5%的CdTe多晶薄膜太阳电池。为了应用高效的镉镉电池制造技术，我们开发了两种生产高效率、高产量和低成本的镉镉电池组件的制造工艺。(C)2004爱思唯尔有限公司。保留所有权利。
Cadmium telluride is a promising photovoltaic material for thin-film solar cells. However, further improvements on performance and reproducibility of devices have been limited by the conventional SnO2/poly-CdS/poly-CdTe device structure used for more than 30 years. In this paper, we review partial R&D approaches at NREL to understand the issues related to the conventional device structure and to develop several novel materials and a modified device structure for minimizing these issues. We have achieved a CdTe polycrystalline thin-film solar cell demonstrating an NREL-confirmed, total-area efficiency of 16.5% by using new materials and the modified device structure. To apply the high-efficiency CdTe cell fabrication technique, we developed two manufacturing processes for producing high-efficiency CdTe modules with the potential of high throughput and low cost.
