Semiconductor Alloy Nanowires for Solar Cells
|
| |
Current State of the Art: Triple Junction Technology
|
| |
 |
|
GaInP: (4-1.82)=2.18 eV heat/waste
GaAs: (1.82-1.42)=0.4eV heat/waste
Ge: (1.42-0.67=0.75 eV heat/waste
|
Proposed Solution:
InGaN nanowires w. varying alloy composition
|
|
- Removal of lattice matching requirement allows continuous change of alloy composition
- Covers almost the entire solar spectrum with one material system
- Continuous bandgap variation avoids heat conversion of extra energy
- Higher efficiency
|
|
- InN and GaN wires have been grown
- In the process of growing InGaN
