Perovskite vs silicon vs thin-film solar: efficiency, cost, and durability compared
Crystalline silicon dominates with 95% market share and 22-24% commercial efficiency, but perovskite tandems promise 30%+ efficiency at potentially 50% lower manufacturing costs. Thin-film CdTe offers advantages in hot climates with lower temperature coefficients. This comparison evaluates bankability, degradation rates, and LCOE across deployment scenarios.
