CdTe is particularly suitable for solar cells because it has a near-optimal bandgap of 1.45 eV, which allows for efficient absorption of sunlight. Additionally, the material has a high absorption coefficient, meaning it can absorb a large amount of sunlight in a thin layer. This makes CdTe ideal for use in thin-film solar cells, which are more cost-effective and less material-intensive compared to traditional silicon-based solar cells.
