LONGi Green Energy's New Breakthrough in Crystalline Silicon-Perovskite Tandem Solar Cells

TapTechNews June 21st news, at the Intersolar Europe 2024 exhibition held in Munich, Germany, LONGi Green Energy announced a new progress in the research and development in the field of crystalline silicon-perovskite tandem solar cells.

The commercial M6-size crystalline silicon-perovskite tandem battery developed by LONGi's tandem team has achieved a photoelectric conversion efficiency of 30.1%, an increase of 1.5 percentage points compared to the previous world record of 28.6%, as independently certified by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).

The theoretical limit efficiency of crystalline silicon-perovskite tandem solar cells is 43%, which is regarded as the next-generation ultra-high efficiency solar cell after the single-crystalline silicon back-contact (BC) cell.

LONGi Green Energy said that this is the first time to achieve more than 30% photoelectric conversion efficiency on a commercial-size crystalline silicon-perovskite tandem battery device, showing a significant efficiency advantage compared to the single-crystalline silicon battery efficiency record of 27.30% just created by the LONGi crystalline silicon team.

TapTechNews note: LONGi Green Energy was founded in 2000 and is a global solar technology company that currently has five business segments: monocrystalline silicon wafers, battery modules, distributed photovoltaic solutions, ground photovoltaic solutions, and hydrogen energy equipment.
