Tandem Perovskite Solar Module Technology
About Tandem Perovskite Solar Module Technology
Tandem Perovskite solar modules combine perovskite materials with traditional silicon solar cells to form a multi-junction structure. This layered configuration allows for broader light absorption and significantly higher efficiency compared to single-junction cells. Tandem modules are at the forefront of next-generation solar technologies, offering an exciting path to surpass the performance limits of silicon alone.
Tandem Perovskite Module Process
Start with a base monocrystalline silicon solar cell (bottom layer).
Deposit a perovskite absorber layer (top layer) with high bandgap.
Apply charge transport layers to manage electron and hole flow.
Add transparent conductive oxide (TCO) layers and antireflective coating.
Integrate into a module with glass encapsulation and sealing.
Test and calibrate the tandem cell for optimal efficiency and reliability.
