Different Generations of Solar Cells
- First generation:
- Single crystal silicon wafer.
- Advantages: high carrier mobility.
- Disadvantages: most of photon energy is wasted as heat, expensive.
- Second generation:
- Thin-film technology.
- Advantages: less expensive.
- Disadvantages: efficiency lower compared with silicon solar cells.
- Third generation:
- Nanocrystal solar cells.
- Enhance electrical performances of the second generation while maintaining low production costs.
