New Inorganic Wide-Bandgap Perovskite Subcells that are both Efficient and Stable

Perovskite solar cells have been gaining popularity in recent years due to their high efficiency and low cost. However, the stability of these cells has been a major concern, as they tend to degrade quickly in the presence of moisture and heat. To address this issue, researchers have been exploring new materials that can improve the stability of perovskite solar cells.

One promising material is inorganic wide-bandgap perovskite, which has been shown to be both efficient and stable. In a recent study, researchers developed a new type of perovskite solar cell that uses inorganic wide-bandgap perovskite subcells.

The new subcells have a bandgap of 1.9 eV, which is wider than the bandgap of traditional perovskite subcells. This wider bandgap allows the cells to absorb more sunlight and convert it into electricity more efficiently. In addition, the inorganic nature of the material makes it more stable than traditional perovskite materials.

The researchers tested the new subcells and found that they had an efficiency of 21.7%, which is comparable to the efficiency of traditional perovskite solar cells. However, the new subcells showed much better stability, with no degradation observed after 1,000 hours of exposure to light and heat.

These results are promising for the future of perovskite solar cells. By using inorganic wide-bandgap perovskite subcells, researchers can improve the efficiency and stability of these cells, making them a more viable option for renewable energy production.
