Bandgap Grading Boosts Perovskite Solar Cell Performance

How does bandgap grading improve perovskite solar cell efficiency?

• Bandgap grading in perovskite solar cells involves gradually changing the composition of the perovskite material to create a gradient in bandgap energy levels.
• This bandgap grading allows for more efficient absorption of a broader range of sunlight wavelengths, increasing the overall efficiency of the solar cell.
• By optimizing the bandgap grading, researchers can tailor the perovskite material to better match the solar spectrum, maximizing energy conversion.
• The bandgap grading technique can also help reduce energy losses from thermalization, where excess energy from absorbed photons is lost as heat instead of being converted into electricity.
• Overall, bandgap grading in perovskite solar cells offers a promising approach to further improve the efficiency and performance of this rapidly advancing renewable energy technology.
