| 内容記述 | Recent pasts have witnessed remarkable progress in the field of bi-facial solar cells (BFSCs) due to their appealing features like enhanced power conversion in a day, the elimination of solar tracking and space-saving. While silicon-based BFSCs have made their way into the commercial market, their higher cost compared to monofacial solar cells has posed a challenge to their widespread adoption. To circumvent this issue, utilization of the bi-facial dye-sensitized solar cells (BF-DSSCs) is one of the cost-effective options but their two intriguing issues such as bi-faciality factor (BFF) and cumulated power conversion efficiency (CPCE) have to be enhanced and demand further optimization. The purpose of this study is the fabrication and characterization of BF-DSSCs aiming towards enhancing the BFF and CPCE by focusing on limiting factors influencing the device performance and proposal for strategies to overcome these limitations. 1st Chapter of this thesis serves as the introductory part providing an overview of the general background of solar energy-related issues and discussing the current advancements in renewable energy, particularly solar energy and solar cells. This chapter also gives an overview of different types of next-generation solar cells and the status of the development of BFSCs, their pros/cons, existing issues in detail and the potentiality of DSSCs towards BFSCs along with the aim and motivation for the thesis. 2nd Chapter of the thesis focuses on the methods and techniques used for the fabrication and characterization of bi-facial BF-DSSCs. This chapter provides a detailed description of the instruments, materials, and methodology employed for device fabrication, characterization and performance evaluation. 3rd Chapter focuses investigation of the absorption and transmission behaviour of different components of DSSCs such as Pt, FTO, TiO2 electrolyte and dye-sensitizer to understand their implication on the performance of BF-DSSCs, especially under rear-side light illumination. It was found that self-light trapping and optical filtering by iodine-based redox electrolyte is responsible for the decreased device performance under backside light illumination. An increase in the thickness of the mesoporous TiO2 layer led to enhanced PCE under front illumination but resulted in decreased overall CPCE and BFF of the BF-DSSCs. Relative transparency of TiO2 layer was also found to control the performance of the BF-DSSCs and utilization of Transparent TiO2 paste (T/SP) leads to improved BFF as compared to its opaque TiO2 paste (D/S P) counterparts from 74 % to 86 % under similar experimental conditions and device parameters. 4th Chapter deals with efforts for enhancing the photoconversion efficiency (PCE) of the BF-DSSCs focusing on enhancing optical absorption window utilizing multiple dye-sensitizers with complementary light absorption. The adsorption behaviour of dyes and their binding strength on the TiO2 surface was investigated systematically in detail and the implication of mode adsorption of two dyes on the performance (CPCE and BFF) of BF-DSSCs was studied. Utilizing the mixture of Z-907 and SQ-140 as a representative visible and NIR dye, it was demonstrated that it is possible to attain the dye bilayer formation from dye cocktail solution, which was significantly influenced by the ratio of dyes and their adsorption time. Results of optimization of device performance of BF-DSSCs, best performance for a dye cocktail of Z-907 and SQ-140 was obtained for a 9:1 ratio with 1 hour of dye adsorption leading to the observation of CPCE of 7.71 % with the appreciably good BBF of 83 %. 5th Chapter deals with approaches to enhancing the performance of BF-DSSCs, focusing on increasing the open circuit voltage (Voc) and BFF utilizing less coloured cobalt-complex redox electrolyte to reduce self-light trapping and relatively deeper redox potential to enhance the Voc. The implementation of cobalt-complex-based redox electrolyte in BF-DSSCs resulted in an excellent BFF of nearly 100%, which has been attributed to its less coloured nature, which leads to the prevention of self-light trapping. Although the Voc of the BF-DSSCs using cobalt electrolyte was slightly increased (due to its deeper redox potential) compared to iodine electrolyte-based device counterparts, cumulative PCE decreased from 13.05 % to 9.52 % due to the non-optimal nature of the dye (D-205) used for the fabrication of BF-DSSCs. Utilization of optimal sensitizers working with cobalt/copper complex-based redox-electrolytes is highly desired and is expected to further enhance the performance of the BF-DSSCs. Finally, 6th Chapter serves as the conclusion of the whole research work, summarizing the main findings and presenting an overall assessment of the research. Additionally, it also included suggestions for future research work to be undertaken based on the finding of the present research to address the remaining gaps towards further improvement in the performance of BF-DSSCs. |
