Evaluation of solar factor using spectral analysis for CdTe photovoltaic glazing
摘要： Solar and luminous light transmission control using Cadmium Telluride (CdTe) based PV glazing systems (15cm × 15 cm × 0.6 cm) were evaluated in this work. Indoor spectral characterisation showed that average solar transmission for investigated three different CdTe glazing systems were 5.77% (CdTe1), 9.54% (CdTe2) and 12.34% (CdTe3). Spectral behaviour of reflections in the range of solar and visible wavelengths was similar for these three different transparent CdTe glazing. Near infrared (NIR) reflection was higher compared to luminous reflection after 1500 nm for all three glazing systems. Solar factor (SF) for CdTe1, CdTe2 and CdTe3 glazing were 0.23, 0.28, 0.26. CdTe3 is the best candidate for glazing application as it has 113% higher luminous transmission while SF only increases by 21% compared to CdTe1.

摘要： Anti-reflective coatings (ARC) are commonly applied to photovoltaic (PV) modules in the solar industry to increase power and energy output. In addition to characterization of initial module power and angle of incidence modifier (IAM), it is important to verify that the expected gain is observed in commercial system operation. This analysis shows the increased performance of ARC First Solar CdTe PV modules compared to non-ARC equivalent modules in a commercial test in New South Wales, Australia. PPI analysis indicates a sustained ARC performance gain over time, suggesting good ARC durability. Detailed actual-expected analysis shows both array types performing at or above expected levels after almost 2 years in the field. ARC arrays show slightly greater benefit than predicted compared to non-ARC arrays.

摘要： Thin-film PV cells with low-cost attractive materials are more appropriate over high-cost silicon-based solar cells as free renewable energy sources. Cadmium Telluride (CdTe) PV cells are widely investigated as one of the ultra-thin film PV cells. They have broadly researched to increase efficiency by improving different front contact and back contact material. the effect of unintentionally formed n-type Molybdenum Telluride (n-MoTe2) in the back contact interface between the Cadmium Telluride (CdTe) absorber layer and Mo layer has been investigated from a numerical analysis by the facilitation of AMPS-1D software. The variation of short circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF) and efficiency (η) are analyzed by changing four parameters like (i) layer thickness (ii) operating temperature (iii) donor concentration and (iv) sun intensity. From the numerical analysis a moderate performance is observed, where the efficiency of the solar cell is found about 16.532%, Jsc is 21.298 mAcm-2, Voc is 0.99 V and FF is 0.863 for the layer thickness, donor concentration, operating temperature and sun intensity at 60 nm, 1×1016cm-3, 350K, and 1.1 suns respectively.

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.

[IEEE 2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT) - Dhaka, Bangladesh (2019.5.3-2019.5.5)] 2019 1st International Conference on Advances in Science, Engineering and Robotics Technology (ICASERT) - Electrical Properties of CSS Deposited CdTe Thin Films for Solar Cell Applications
摘要： CdTe is a very potential absorber material for thin film solar cell application. In this work CdTe thin films (TF) were deposited on CdS thin films by close-spaced sublimation (CSS) technique at different source and substrate temperature in inert gas condition. To bring out the optimum temperature set for CSS deposited CdTe films, several experiments were done. The process pressure of the chamber during deposition was maintained at 1.5 Torr in a dynamic condition. The effects of deposition temperature on the electrical properties of the as-deposited CdTe films were investigated by Hall Effect measurement. The films were deposited at 610 0C, 630 0C, 650 0C and 670 0C source temperatures. The first three films showed p-type conductivity while n-type conductivity appeared in the film deposited at 670 °C. The hole concentration of the as-grown p-type CdTe films followed an upward trend with the increase of source temperature and it reached a peak value at 650 0C. The highest hole mobility was observed for the lowest source temperature. However, the resistivity of the CdTe films was found increasing with the increase of source temperature. Thus, the CdTe thin film deposited at 650 0C showed better electrical properties for solar cell applications.

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.
