Press Release NOVELLUS SYSTEMS AND THE UNIVERSITY OF SOUTH FLORIDA
 

Summary: Press Release
NOVELLUS SYSTEMS AND THE UNIVERSITY OF SOUTH FLORIDA
RECEIVE NATIONAL SCIENCE FOUNDATION GRANT
TO IMPROVE SOLAR CELL EFFICIENCY
Atomic Layer Deposition Process Based on Joint Novellus and University of South Florida
Technology Tailors Solar Cell Structures for Improved Energy Conversion
SAN JOSE, Calif., ­ November 30, 2011­Novellus Systems (NASDAQ: NVLS) today
announced that it is a co-recipient of a National Science Foundation (NSF) grant, along with the
University of South Florida (USF), to study the precise engineering of solar cell interfaces. The
company's work with USF will focus on using Novellus' conformal film deposition (CFDTM)
technology, an atomic layer deposition process, to fabricate solar photovoltaic (PV) materials.
The Novellus and USF research effort will focus on using CFD to grow conformal metal oxide
and metal nitride dipole layers in the PV cells that exhibit highly controlled atomic layer film
thickness and uniformity. By so doing, the team hopes to be able to adjust the band alignment in
the cell for optimized charge transfer or blocking, a process that has the potential to controllably
enhance both the photocurrent and voltage in the cell. The goal of the research is to develop
scalable manufacturing technology for these large-area dipole layer coatings that will allow PV
solar manufacturers to precisely tailor the electronic properties of solar cell structures, leading to
increased solar energy conversion.
The strength of the Novellus and USF research team investigating improved PV efficiencies lies
