Launched in 1999,
PV Measurements, Inc. provides performance
characterization instrumentation for solar cells and modules. Halden Field,
the company's leader and founder, has worked in the
photovoltaics field for 18 years, focusing on performance
characterization for 15 years. Our skilled staff of engineers and technicians is dedicated to
building high quality products at reasonable cost.
Customer List and References
Many new customers
would like to see a list of our existing customers before purchasing
our products for the first time. However, most of our existing customers
do not want us to publicize this information. Instead, we offer the following
statistics to illustrate the popularity of our
products:
Reference Cells:
More than 400 units sold
Spectral Response
/ QE / IPCE Measurement Systems: More than 50 systems sold worldwide to companies, universities
and prestigious research laboratories. We believe we have built more of these systems for end-users
in the photovoltaics field than any other company.
And since we are well-known in the photovoltaics
field, prospective customers may wish to ask their
colleagues for a reference.
