(Konica Minolta: Ramsey, NJ) -- Konica Minolta Sensing Americas (KMSA), a global leader in the industrial measurement of color, light and 3-D shape, launched its AK-120/130/140 Photovoltaic (PV) Reference Cells, the world's first triple-junction solar reference cells.

Now available, 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. Reference cells are used as a standard point of calibration to ensure consistent measurements of newly developed photovoltaic cells.

Developed in conjunction with the National Institute of Advanced Industrial Science and Technology in Japan, the AK-120/130/140 is the world’s first triple-junction (top/middle/bottom) reference cell. The reference cell has been uniquely designed using an optical filter mounted on a stable crystalline silicon solar cell.
