[IEEE 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Chicago, IL, USA (2019.6.16-2019.6.21)] 2019 IEEE 46th Photovoltaic Specialists Conference (PVSC) - Application of Solution-Processed CuSCN and AgSCN for High Efficient CdTe Solar Cells
摘要： Solution processed CuSCN and AgSCN were employed as Cu and Ag doping source in the CdTe solar cell. The effect of Cu and Ag on the CdTe device performance was investigated. It is promising to show that the CuSCN and AgSCN with similarity role to increase devices performance to power conversion efficiency to 17% and 16%, respectively. The benefit from CuSCN is that the dual role of CuSCN, one is the hole transport layer and one is Cu doping, while AgSCN with a higher resistive may play as Ag doping source with slower diffusion rate.

Scientific complications and controversies noted in the field of CdS/CdTe thin film solar cells and the way forward for further development
摘要： Cadmium telluride-based solar cell is the most successfully commercialised thin film solar cell today. The laboratory-scale small devices have achieved ~ 22%, and commercial solar panels have reached ~ 18% conversion efficiencies. However, there are various technical complications and some notable scientific contradictions that appear in the scientific literature published since the early 1970s. This review paper discusses some of these major complications and controversies in order to focus future research on issues of material growth and characterisation, post-growth processing, device architectures and interpretation of the results. Although CdTe can be grown using more than 14 different growth techniques, successful commercialisation has been taken place using close-space sublimation and electrodeposition techniques only. The experimental results presented in this review are mainly based on electrodeposition. Historical trends of research and commercial successes have also been discussed compared to the timeline of novel breakthroughs in this field. Deeper understanding of these issues may lead to further increase in conversion efficiencies of this solar cell. Some novel ideas for further development of thin film solar cells are also discussed towards the end of this paper.
