RESEARCH AND DEVELOPMENT.................................................. PAGE 2
* Shared R&D 100 award with United
Solar for triple-junction amorphous silicon
PV roofing module.
* Won IEEE Electrotechnology Transfer
Award by moving high-efficiency GaInP2/
GaAs tandem solar cell to industrial
* Fabricated 15.4%-efficient cadmium
telluride device using process that is easy
* Exceeded planning goal for 1999 by
supporting development of 16.6%-efficient
cell made of thin-layer crystalline silicon.
* Reduced module-manufacturing costs by
more than 32% and doubled manufacturing
capacity in the last three years of the
* Supported introduction of new products:
ac PV modules (featured in "The Best of
Whats New for 1998" in Popular Science);
packaged PV systems; and improved
* Extended support of PV system and
component development and PV module
manufacturing technology by issuing
14 new, cost-shared, two- or three-year
contracts to industrial partners.
* Fabricated and tested a 17.2%-efficient
back-contact emitter wrap-through crystal-
line silicon cell.
* Demonstrated a 12%-efficient solar device
to split water into hydrogen (a valuable
fuel) and water.
* Met two major planning milestones for
CIS (copper indium diselenide): supporting
debut of first commercial products; docu-
menting their performance at 10% efficiency.
* Awarded 34 new cost-shared, three-year
subcontracts under the Thin Film PV
* Introduced highly accelerated lifetime
testing (HALTsM) protocols to inverter
manufacturers to help detect and correct
* Augmented module testing facilities with
test bed for small systems, high-voltage test
bed, expanded outdoor test bed for energy
ratings, and outdoor accelerated weathering
* Improved inverter production with con-
tracts supporting improvements in quality
* Maintained more than 60 secure Web
sites to transfer measurements and charac-
terization data of materials and devices to
industry and university partners.
* Completed three years of educational
projects for students in cooperation with
historically black colleges and universities
and solicited project proposals for another
* Awarded 17 subcontracts to universities
to upgrade their research equipment and
improve their PV R&D capabilities.
* Identified conditions surrounding, and
developed strategies to deal with, islanding
of PV systems connected to the utility grid.
* Extended module performance charac-
terization procedure to characterization of
arrays and of systems, and initiated devel-
opment of more accurate models of energy
SYSTEMS ENGINEERING AND APPLICATIONS......................................PAGE 14
* Contributed to major new standards and
certification applying to PV systems: IEEE-
recommended practice for utility interface;
interim test methods for determining the
performance of small systems; PowerMark
Corporation accreditation of certification
laboratories; and revisions to the National
* Assessed performance of PV installations
owned by federal agencies, operating as
hybrid systems, and of utility-owned, grid-
connected systems on rooftops.
* Provided technical assistance to major
demonstration projects-Million Solar Roofs,
TEAM-UP, and the PV Pioneer Program-by
supporting training programs for installers,
workshops for communities, and public
* Displayed popular PV exhibits at EPCOT
Center@ in Orlando, FL, and Smithsonian
Institution's Cooper-Hewitt National Design
Museum in New York City.
* Made spectral solar data and selected
solar radiation and cloud cover maps acces-
sible from the NCPV Web site.
* Continued PV:BONUS by selecting seven
projects for innovative building-integrated-
PV product and business development.
* Provided technical assistance to many
countries; met major milestones in Brazil,
China, India, Mexico, and South Africa.
