Designing Indoor Solar Products 
Photovoltaic Technologies for AES

Photovoltaic technology – or the direct conversion of light into
electricity – is the fastest growing means of electricity
generation today, however it is generally used outdoors. Relatively
little attention has been focused on the many obstacles to overcome
when designing efficient indoor products. As a result, indoor
products are more often than not limited to low power. Designing
Indoor Solar Products bridges this gap by showing where AES
(Ambient Energy Systems) based on photovoltaic cells may be used
for higher power devices.

Motivated by both financial and ecological arguments, this
book:

* Co-ordinates a wide-reaching range of scientific information
regarding photovoltaic technologies and their application to indoor
spaces.

* Analyses power management, power availability, technological
selection and design methodologies.

* Uses real-life examples and case studies to demonstrate the
arguments made.

* Presents information in such a way as to make it accessible
even to engineers with basic electrical knowledge.

Designing Indoor Solar Products pulls together a wealth
of information on photovoltaic technologies and their applications.
It will be of practical interest to engineers and designers of
sensor systems planning on using photovoltaic technology for power,
whilst the theoretical approach will appeal to those in academia in
the related areas of environmental engineering, sustainable
development as well as building and product design.
