Triple-junction solar reference cells

Konica Minolta

Konica Minolta Sensing Americas, Inc. has launched its AK-120/130/140 Photovoltaic (PV) Reference Cells, the world's first triple junction (top/middle/bottom) solar reference cells. Reference cells are used as a standard point of calibration to ensure consistent measurements of newly developed photovoltaic cells.

The AK-120/130/140 is the latest addition to the AK Series of reference cells. KMSA first introduced its AK Series in 2010 at the SPIE Optics and Photonics conference to much industry excitement.

Developed in conjunction with the National Institute of Advanced Industrial Science and Technology in Japan, the AK-120/130/140 has been uniquely designed using an optical filter mounted on a stable crystalline silicon solar cell.

AK-120/130/140 Main Features:

  1. Spectral mismatch error less than 1%
  2. Ready for immediate use
  3. Improved durability against solar simulator light
  4. Zero errors caused by multiple reflections
