Spi-Cell Sorter™
High-Throughput Automated
Solar Cell Tester

T

he Spi-Cell Sorter™ sorts photovoltaic cells according
to their electrical performance, tested under simulated
sunlight. A pulsed xenon lamp with an optical filter provides
a close match to the Air Mass 1.5 Global solar spectrum. The
spectrum meets the highest International and ASTM
specifications (ASTM E927 Class A). The system features
automatic cell handling of coinstacked cells and
sorts the tested cells into ten output bins.
A computer with user-friendly software adjusts the
lamp intensity, controls the measurement process
and cell handling, and acquires cell performance
data. The data, as a full I-V curve, allows sorting by a
variety of selectable criteria. The computer plots the
I-V curve and displays a variety of cell characteristics.
Curves and data can be printed and stored on disk.

Automated cell handling gently positions each cell for electrical
testing under simulated sunlight

Sorts PV cells according to electrical performance

Tested cells are sorted into output bins according to the
cell’s electrical performance.
