| Description | The most important parameters for solar cells is the open voltage and short circuit current. We have demonstrated methods to increase short circuit current by using InAs quantum dots in GaAs solar cells. We have been working on the improvement of open voltage for GaAs-based InAs quantum dot solar cells. Based the outputs of this programme, new collaboration with US Army Research Lab has been established, and we won an EU programme on quantum-dot solar cells. |
| Exploitation Route | These findings are in early stage of research. In long term, energy companies could take these finding into their high-efficiency solar cells. |

| Description | We aimed to develop low-cost and high-efficiency solar cells with exploiting III-V nano-structures in this project. Our findings have been published in more than 34 peer-reviewed publications and presented a few times in international conferences. Although the total efficiencies of quantum-dot solar cells are still lower than those of best bulk solar cells due to the reduced open voltages of solar cells, high radiation resistance was recently observed in quantum-dot solar cells, which could be used in the low-intensity-low-temperature conditions of the target planets Saturn, Jupiter, and Mars. |
