Peafowl Solar Power is a spin-out from Uppsala University, Sweden, that has developed a groundbreaking transparent solar cell. Our technology enables the next generation of smart buildings and self-powered IoT devices.

1. Overview
May 2020

2. THE PROBLEM
• Today: 7 billion connected devices
• 2022: 25-30 billion connected devices1
• Scaling with power wires or batteries is not feasible

3. CURRENT STATUS OF
SOLAR CELLS FOR
ENERGY
HARVESTING
Current solutions limited by
• Aesthetical compromises
• Energy source availability
• Unsustainable materials
• Unreliable power supply
• Manufacturing difficulties
WE NEED MORE OPTIONS!

4. SOLUTION:
DEVELOP A
COMPLETELY
TRANSPARENT
SOLAR CELL
Peafowl’s direct plasmonic solar cell –
highly transparent photovoltaics
THE MODERN FAMILY WANTS TO BE
CONNECTED – WITHOUT WIRES OR
BATTERIES

5. • Truly transparent
• Tailored colours
• No compromise
VALUE PROPOSITION:
POWER FOR A TRILLION SMALL DEVICES
AESTHETICS SAVINGS FLEXIBILITY RETROFITTING SUSTAINABILITY
• Self-sufficient
devices
• No cabling
• No battery
changes
• Indoor or
outdoor
• Adaptive to light
source
• On any smooth
surface
• Fit into pre-
existing buildings
and design
• Make all buildings
smart
• Enabler of
sustainable, energy
saving smart
buildings and cities
• Sustainable
materials and
manufacturing

6. Cities account for two-thirds of energy consumption and 70% of CO2 emissions globally

7. HVAC – heating ventilation & air conditioning account for 51% of the energy use
Smart regulation can cut this by 15%
No compromise for the tenants: A “smart” building has better temperatures and air quality,
and higher comfort and productivity
Example: ”The Edge”
One of the worlds’ most
sustainable buildings,
completed in 2015
Extensive sensor system
monitoring daylight, ambient
temperature, CO2 levels,
occupancy, motion
This system enables adaptive
control of light, heating,
ventilation and even cleaning
Existing smart building technology
could create sustainable cities

8. Lack of power solutions is a
barrier to implementation
The Edge has 30 000 sensors
Smart Homes: 2.2 billion wireless
devices in 2022
Cable installations are expensive
and feasible only for new
buildings
Batteries rely on cobalt, lithium,
nickel – limited resources with
fragile supply chains
Batteries need changing every
10 years
What can be done in one
building with battery-driven
devices cannot be easily
deployed into millions of
buildings
This will not work with
batteries as usual

9. PeafowlGlass enables scaling of smart building technology
1m2 can power
8-10 sensors
Window

Picture frame
glass
Coffee table
an ultra-thin solar cell layer is
printed on transparent glass or
plastic
a self-powered smart glass
with embedded sensors
can be mounted on any
smooth surface
unlocking the potential of sustainable buildings
provides data to optimize
the building system

10. MAKING BUILDINGS MORE SUSTAINABLE, MORE COMFORTABLE
AND MORE PROFITABLE
• Increased comfort
• Lower energy bills
• Aesthetics: Truly
transparent,
colourless or
tailored colours
Glass
manufacturers
Building owners
Building
renovators
Building managers Tenants
• Simple
manufacture
• Added value to
exiting products
• Access to
growing IoT
market
• Easy to install
• Can be retro-fit into
any building
• Make all buildings
smart and open to
IoT data
• Data gathered improves building efficiency
• Automation reduces building management
system (BMS) costs
• No cabling + no battery changes
• Sustainable materials and manufacturing
60% ↑
energy savings
25% ↑

€10k saved
per year*
*cost of battery replacement in standard commercial building with 30,000 sensors
↑ increased
productivity
↑ added comfort

11. Enabled by our
patented high-
transparency solar cell
A direct plasmonic solar cell:
A completely new mechanism for
capturing light with plasmonic
nanoparticles
Contains no toxic or rare materials
that inhibit deployment or scaling
Works for both indoor and
outdoor light conditions

12. Prototype, STC:
0.7 V
20 μA/cm2 (0.2 mA/m2)
90+% transparency
TECHNOLOGY
• Direct plasmonic solar cell – a new
patented technology
• 10x higher light absorption than other
known materials
• One photon generates multiple electrons
• Extreme absorption enables high
transparency – can also be tinted
• No rare earth or toxic materials
• Printing technology makes
manufacturing low-cost, low-energy and
flexible for all surfaces – meaning it can
be applied on glass, plastic, flexible
polymers etc
• Works in-door and outdoor
• Can use the whole light spectrum, or
tuned to specific wave lengths

13. TUNABLE INK
Multi-colour configurable
applications, including
very high transparency
Each colour represents a
shape of the nano-
particle and a spectrum
of light absorbed

14. PeafowlGlass is the most promising solution to solve
the power bottleneck
