A South Korean firm has announced the world’s first production line for perovskite-silicon tandem solar cells, which promise an increase in efficiency of between 50-75 per cent compared to ...
Solar-cell efficiencies of laboratory-scale devices using these materials have increased from 3.8% in 2009 [3] to 25.7% in 2021 in single-junction architectures, [4] [5] and, in silicon-based tandem cells, to 29.8%, [4] [6] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells have therefore ...
With a theoretical efficiency limit of 43 per cent for a perovskite tandem cell – compared to a 29 per cent limit for a standard silicon cell – the new panels also offer a way to supercharge ...
Currently, there are several commercial (non-Perovskite) multi-junction technologies including tandems and triple- and quadruple-junction modules that typically use III–V semiconductors, with promising power conversion efficiency that rival and even outperform the benchmark silicon solar cells.
One example is amorphous silicon solar cells, where triple-junction tandem cells are commercially available from Uni-Solar and other companies. In 2023 Chinese manufacturer LONGi Green Energy Technology Co. announced a tandem silicon/perovskite cell that achieved 33.9% efficiency, the first time a silicon-based cell has exceeded the S-Q limit.

Tandem solar cells combine two materials to increase efficiency. In 2022 a device was announced that combined multiple perovskite with multiple layers of silicon ...
