Context: The Union Minister for MNRE, lauded NCPRE’s breakthrough in Silicon-Perovskite Tandem Solar Cells with a record 29.8% efficiency, calling it a game-changer for India’s solar future.
About Silicon-Perovskite Tandem Solar Cells:
• What It Is? A tandem solar cell combines two types of solar materials—silicon and perovskite—stacked to absorb different parts of the sunlight spectrum. This structure boosts energy conversion efficiency far beyond conventional silicon panels.
