Record efficiency achieved for perovskite-silicon triple-junction solar cells
Swiss labs develop a triple-junction solar cell with over 30% efficiency, nearing costly III-V cell performance while enabling more affordable solar energy capture.
- Researchers from the Swiss Center for Electronics and Microtechnology and EPFL reported a triple‑junction solar cell exceeding 30% efficiency on a single device integrating perovskite and silicon subcells.
- Their 2018 demonstration recorded 13% efficiency, while recent years have seen triple‑junction design upgrades and device processing improvements enhance performance and resilience.
- Kerem Artuk, lead author, said, 'We show that with clever design and processing, we can approach performance levels traditionally reserved for the most expensive III‑V multi‑junction solar cells used in space.' Triple‑junction architectures offer efficiency potential well above 40%, exceeding single‑junction and tandem limits.
- The development suggests combining perovskite‑silicon captures more solar spectrum and is cost efficient, opening the door to industrial‑scale photovoltaics after overcoming laboratory scaling challenges.
- Future work will focus on scale‑up efforts as upgrades push perovskite‑silicon stacks toward the efficiency ceiling above 40%, researchers report.

myscience.orgRecord efficiency for perovskite-silicon triple-junction solar cells
EPFL and CSEM researchers have achieved a record 30% efficiency for triple-junction solar cells, which combine two thin-film perovskite cells and one silicon cell on a single device. The milestone could advance affordable next-generation solar technologies for space and terrestrial applications.
Record efficiency achieved for perovskite-silicon triple-junction solar cells
Researchers from the Photovoltaics and Thin-Film Electronics Laboratory (PV-Lab) in EPFL's School of Engineering and CSEM have developed a new solar cell that combines exceptional voltage, high efficiency, and scalable manufacturing. The triple-junction device is composed of a silicon bottom cell, onto which middle and top cells made of semiconductors called perovskites are deposited as thin films. The new device, according to the paper publishe…
Triple-junction solar cells with improved carrier and photon management
Perovskite-silicon triple-junction photovoltaics offer efficiency gains beyond dual-junction devices, but at the expense of added complexity (1). Here, we address two key bottlenecks in perovskite-silicon-based triple-junction solar cells: reduced open-circuit voltage in the wide-bandgap top-cell and limited photocurrent generation in the middle-cell (1, 2). A non-volatile additive, 4-hydroxybenzylamine, regulates wide-bandgap perovskite crystal…
Researchers achieve world record efficiency of 30.02% in perovskite-silicon triple-junction solar cell
An international research team, including scientists from the University of Queensland, boosted triple-junction solar cell performance by enhancing perovskite crystal growth, increasing middle-cell light absorption, and adding reflective nanoparticles.Researchers from the Swiss Center for Electronics and Microtechnology (CSEM) and the École polytechnique fédérale de Lausanne (EPFL) claim to have achieved a power conversion efficiency exceeding 3…
