Abet Technologies, Inc. products

The Abet Technologies solar reference cell is a precision instrument for the determination of solar simulator irradiance levels. The sensor is a mono-crystalline silicon solar cell having an area of2x2cm(4cm).The back of the solar cell is attached to the device in such a way that a good heat transfer to the device housing is guaranteed. Below the solar cell a Pt100 RTD temperature sensor is mounted to allow monitoring of device temperature. The device is not shunted allowing the whole IV-curve to be measured. The solar cell is protected by a high quality fused silica window, assuring spectral sensitivity over a 320 -1100 nm range.

Multi-Junction solar cell metrology is more complicated than that of a single junction one. As these cells are made of multiple layers, a multi-source/LED solar simulator is usually employed to allow adjustment of band to band irradiance ratios. Our triple junction reference cells can be used to set the correct irradiance for each single junction.
