At Sol Ideas, we have applied over
20 years of experience in optoelectronics for the benefit
of our customers. Our projects include
Optoelectronics
of Solar Cells
Greg P. Smestad's book Optoelectronics
of Solar Cells provides an overview for those
in the fields of optics and optical engineering, as well as
those who are interested in energy policy, economics, and
the requirements for efficient photo-to-electric energy conversion.
This book can be ordered
online.
Light Emitting Diode Optics
Light
Emitting Diodes (LEDs) are increasingly being used to replace
energy wasting incandescent bulbs in applications ranging
from automotive signaling to residential lighting. Sol Ideas
founder, Greg P. Smestad, was a pioneer in the use of non-imaging
optics used in solar concentrators. For LEDs, he reversed
the design to efficiently bring light from the chip to viewer.
This led to several patents and practical applications.

reader - See Note):
These designs inspired products being
sold today. They can also serve as inspiration for next generation
photovoltaic concentrator solar cell package designs.
UV
Waterworks Safety Shut-Off
Dr. Smestad designed and prototyped
a UV detector and housing for a safety shut-off on the UV
Waterworks water purification system for Waterhealth
International. This allows for an efficient, affordable
water disinfection device that uses ultraviolet light to disable
bacteria and viruses in drinking water, making it safe to
drink. The
patented UV detector/controller ensures that water will
be sterilized only when there is sufficient UV irradiance.
This unit assists in providing drinkable water at low cost
in developing and developed nations.
Note: To read PDF files you will need
the Adobe Acrobat reader, which can be downloaded free from
the Adobe
web site.
