Thinner electrodes and increased layer thickness enable significant technological advancements.

Panasonic’s hydrogenated amorphous silicon (a-Si:H) solar cells, known as Amorton, have long powered various indoor and outdoor applications, including IoT devices, watches, sensor nodes, asset trackers, and remote controls. These cells efficiently harvests energy even in low-light and artificial-light conditions. The company introduced series: AMG-1401C and AMG-1701C. These new models feature a black-reflective surface and significantly enhanced efficiency, achieving a 20% boost. This improvement stems from an optimized production process that expands the active area compared to previous models. As a result, the AMG-series is among the most efficient indoor amorphous solar cells available. 

The key specifications include:

  • Both models are built on glass substrates
  • Thickness: 1.1mm
  • Energy generation: approximately 8uW/cm² at 200 lux per active area
  • External dimensions are slightly larger than the active area for space and material optimization
  • Dimensions: 41.4mm x 26.1mm
  • Maximum energy generation: 77.8uW at 200 lux
  • Cell voltage: 2.2V

The external dimensions are slightly larger than the active area to optimize space and material usage. These solar cells are designed for a variety of energy harvesting applications, ensuring efficient performance. Additionally, they are compatible with a wide range of power management ICs available on the market, making them versatile and adaptable for different systems.

“We are thrilled to launch the new indoor Amorton solar cell series, marking a significant advancement in amorphous silicon solar cell technology,” says Robert Spiegler, Lead Product Manager Solution Business at Panasonic Industry. “Our extensive R&D and production expertise has enabled us to develop solar cells that excel in both appearance and performance. Additionally, we can customize solar cells for small electronic devices according to customer requirements, including transparent surfaces for applications involving displays.”
