Surpassing Shockley–Queisser Efficiency Limit in Photovoltaic Cells (IMAGE)
Caption
- A record power conversion efficiency of 50%–60% was achieved in Si solar cells by inhibiting the lattice atoms’ thermal oscillations at low temperatures.
- Enhancing the light penetration depth can effectively mitigate carrier freeze-out and expand the operational temperature range of silicon cells to 10 K.
