Sunpreme produces thin-film solar panels using Hybrid Cell Technology that combines the efficiency of amorphous silicon with lower temperature processing advantages. Their panels have efficiencies up to 22.5% in R&D and 22% in production, as well as bifacial double glass construction that provides 10-20% higher energy output. Sunpreme has established production facilities and sold panels across five continents for uses such as commercial rooftops, carports, and ground mounts.

2. Sunpreme’sUniqueBifacialCells-A3rdGenerationEmbodiment
Sunpreme’s cells consist of thin film p-i-(wafer substrate) – i-n junction formed by four
amorphous silicon thin film depositions. Each layer of a-Si:H film on front and back of the cell
is only 20 mono- layers (~6nm) thick. The resulting PV cells with such sharp nano-emitter and
nano-collectors provide high efficiencies expected from the best heterojunctions, a higher Voc,
and hence a lower thermal coefficient.
Since both terminals of the junction are located in the deposited amorphous silicon layer, the
cell is much more forgiving of impurities in bulk of the Si substrate. The role of Si substrate in
HCT is primarily to provide a light absorbing material with high electron mobility and a stable
mechanical/thermal interface to the a-Si:H films. The deposited film does not interact with the
substrate at the low (<250C) process temperatures.
The transition from crystalline Si bulk to the amorphous film is atomically abrupt. In contrast a
crystalline PV contains a diffused p/n junction, 100~300 nm into the wafer; hence it is prone to
defects in the wafer and 60mV lower Voc.
Our5-stepManufacturing
ProcessDeliversHighYield,
LowerCost
The production process is a lean
5-step sequence with a cycle
time of only 6 hrs. It includes
PECVD for a-Si:H stack, both
undoped and doped, and a PVD
step for TCO films. The films are
deposited both on the front and
back side of the substrate for bi-
facial action.
Both of these deposition systems
use a similar design as has been
proven out for TFT LCD displays.
But instead of glass, we deposit
on Si substrates.
Bi-facialModules
We pioneered Bi-facial double glass frameless modules nearly four years ago.
These panels are well differentiated in providing 10-20% higher energy boost from
reflected, diffuse light, with a 3x higher level of reliability than industry certification
requirements.
And, superior world-class aesthetics. The module efficiencies can easily reach
22% in real-world applications. Moreover, the efficiency remains high even at low
irradiance seen around dawn and dusk, as well as in haze or fog.
CellEfficiencies
Our cell efficiencies are as high as 22% in
production using Ag paste for optimized
bi-facial fingers and bus bars. In R&D, we
have developed a precision Cu patterning
process that results in a cell efficiency of
22.5% at a Voc of 745 mV and a Fill Factor
of 0.80 leading to a Pmax of 5.4W for a
156 mm cell.

Sunpreme’sUniqueBifacialCells-
A3rdGenerationEmbodiment
Sunpreme’s family of thin film bifacial
modules addresses “Customer Careabouts”
for every application. High power density,
up to 370W STC plus 10-20% backside
boost, makes GxB modules ideally suited
for Distributed Generation projects such
as commercial rooftops where space is
at a premium. Residential, carport, and
canopy installations will benefit with the
aesthetically pleasing frameless design, a
sleek 6mm (4mm for SL) profile, and clear
backside glass enclosure. For ground mount
utility scale applications, the 500W“Heavy
Watt Champion”will dramatically reduce
balance of system and installation costs
while minimizing land usage.
ByDesign-Rugged,YetSleek
Sunpreme modules double glass construction are strong enough
to withstand hurricane force winds with superior salt spray and
sand erosion, making it rugged enough for environments such
as tropics, deserts, and even Antarctica – locations not normally
well suited for conventional panels. Yet, with an ultra-thin profile
of 4-6mm without a frame or unsightly plastic back sheet, our
modules are attractive enough to display in prominent structures
like carports, terraces, and residential rooftops.
SettingtheBenchmarkinRealWorldEnergyProduction
Sunpreme panels generate more energy, up to 100% AC output
of the DC STC rating vs. 80-85% from a conventional panel. This
is achieved with the lowest thermal degradation coefficient,
zero light induced degradation, and backside boost. The result is
reflected in >10% greater energy yield KWh than what is predicted
by PVSyst modelling and the lowest LCOE. In recognition to our
panels’industry leading performance, The Principal Solar Institute
awarded Sunpreme 7 out of top 10 spots in their survey of thin
film panels.
CertifiedReliable,InsuranceBacked
Independent testing centers have certified to IEC, UL, and
other international standards. In fact, Sunpreme panels exceed
3x industry standards with extended reliability tests such as
damp heat cycling for 3000 hours and PID free at 250 hours.
Giving further assurance, all panels are backed with a 25 year
performance warranty backed by a leading European insurance
company, thereby avoiding any concerns with typical company
balance-sheet funded warranty claims.
