In this work, a theoretical study has been performed to evaluate the performance of hybrid triple-junction (HTJ) solar cells under different operating conditions. A numerical model based on a detailed balance limit has been developed for multi-junction junction cells. In the proposed design (HTJ), the interconnection between sub-cells has been modified. In the modified design, bottom and middle sub-cells are connected in series and this segment is connected with the top sub-cell in parallel. This study demonstrates that modification in the interconnection between sub-cells brings a considerable change in the conversion efficiency. Hybrid triple-junction (HTJ) solar cell performance is much better in higher temperatures as compared to that of a conventional series-connected triple-junction (TJ) solar cell. The relative dip in conversion efficiency due to the temperature rise is low in the HTJ structure as compared to a conventional series-connected triple-junction (TJ) solar cell. At the same time, it has been observed that at higher concentration level, modified design HTJ solar cell performance is much better as compared to that of a conventional series-connected triple-junction (TJ) solar cell. This theoretical study could be helpful to explore new design concepts of a multi-junction solar cell. [ABSTRACT FROM AUTHOR] |
