Description
Pravin Pawar and five colleagues wrote a 2026 review on tandem solar cells that stack two light-absorbing layers. One layer is CIGS, a copper-based film, and the other is perovskite, a crystal material that is cheap to make. Together they catch more of the sun's spectrum and can approach the top efficiency limit of about 45 percent.
The best such cells have passed 31 percent efficiency in the lab. The main drag on performance is defects at surfaces and at the joint between layers. These defects waste energy and speed up wear. The review sorts the defect types and the fixes engineers use, such as coatings and layer treatments, to push tandem cells closer to real-world use.
