Dr. Marc A. Anderson received his BS and MA degrees in
chemistry. Between his MA and Ph.D. degree programs, the Viet
Nam Conflict interrupted Dr. Anderson’s education. During this
time he served as an Officer in the Chemical Corp of the USArmy
and was stationed at Edgewood Arsenal, Md. Here, Dr. Anderson
served as the Chief Officer Responsible for Agent Response and
also worked in the “Super Toxic” Laboratories in the area of Binary
Agent production. After returning to Civilian life, he completed his
Ph.D. degree in Environmental Engineering at Johns Hopkins and
joined the faculty at the University of Wisconsin in Civil and
Environmental Engineering. Prof. Anderson is now retired but previously served on the faculty of the Materials Science Program and was the Chair of the Environmental Chemistry and Technology Program. Although retired from UW Madison, Prof. Anderson serves as a the head of the Electrochemistry Diviision of Imdea Energia in Madrid Spain.

Prof. Andersons research efforts focus on
the preparation, characterization and utilization of nanoparticulate
oxides. These particles are on the order of 2-10nm in diameter
and are typically used in the form of thin films cast on a variety of
supports for a large array of applications. These applications
include: ceramic membranes for gas and liquid separations; high
surface area electrodes for use in fuel cells, batteries, capacitors
and solar cells; nanoporous films for use in sensors to be
employed for the detection of target species in both the gas and
liquid phase; and photocatalysts for the destruction of organic
compounds in the water we drink and the air we breathe. In this
last area, Dr. Anderson is considered one of the foremost world-
class experts in photocatalysis. Dr. Anderson’s has more than 25
patents and over 250 scientific papers.

Abstract

Solar energy has been growing at an exponential rate over the past decade, and worldwide installed solar electric capacity is expected to more than double again by 2020. Madison Area Technical College and the Center for Renewable Energy Advanced Technological Education (CREATE) have been on the forefront of this trend, developing and teaching solar energy education courses for STEM students. Solar panel performance is unfortunately limited in the field when panels become soiled over time, reducing their electric output. In this student initiated experiment, solar panels were treated with a nanoporous silica/titania metal oxide thin film coating to impart self-cleaning properties. Panels from an operational 1.6 kW solar array were coated in the field to model a real-world application process. The system incorporated module level micro-inverters to monitor the power output of individual panels. The system was installed in July, and coatings applied in October, 2017. Data collection and analysis is ongoing. Through this research project, students learned the fundamentals of solar photovoltaic technology, aspects of solar system design, safe installation procedures, and principles of data analysis.
