Automotive: why?

Solliance Application Program

▪ 6

A PV system in the car could contribute between 500 and 1000 Watt

in sunny conditions

• This is not sufficient to (instantly) power a car

• But:

Across the day – knowing that a car is parked most of its time – this can

contribute a significant part of the

required energy (range of 20%)

It can contribute to the comfort

by (continously) powering the

airco-system which matches well

with sunny conditions

Business logic from PV industry

Translucent Foil

▪ 7

Strong demand from automotive players

• Strong pressure for measures to reduce CO2 emissions

• PV makes perfect sense but not used because of aesthetic reason

Yearly production of 100 million new vehicles

• Average vehicle area of 15m2

At 50 Euro per m2 this represents a PV foil market of 75 billion Euro

per year

Today…. Tomorrow…?

How do they do it?

▪ 9 29 november 2016

Industrial proven technique

▪ 10

Car wrap foil technique

• Nicely conforms with non-flat surfaces

• Perfect aesthetics

29 november 2016

Process on car wrap foil

▪ 11

Car wrap foils come in any colour

This includes semi-transparent foils

29 november 2016

Challenge

Translucent Foil

▪ 12

Develop a car wrap foil with a translucent PV coating

Key requirements:

• Translucent

Appearance of a transparent coating

No visual impact on texture and colour of the underlying material

• Form-free

Should conform with the shape of the underlying material

• Flexible (2,5D 3D (deformable))

Should conform with non-flat surfaces (e.g. automotive)

Sunpartner Technologies

Translucent Foil

▪ 13

They own an IP portfolio on making transparent PV coatings on glass for

display applications (2016-03-07: 23 patent applications published so far)

Portfolio includes optical patterning and techniques to make the electrical

contacts invisible

Demonstrated on 30x30 cm glass

and positioned for energy harvesting

on smartphones and smartwatches

• French R&D company

• 50 employees

• Clean-room facilities for demo production

• Business model of licensing their IP to

3rd parties

Hyet Solar

Translucent Foil

▪ 14

Hyet Solar (21 published patent applications)

• They own an IP portfolio to make flexible PV foil based using a

temporary Al foil for the processing of the PV layers

(see further why we will need to use this technique)

• Also own IP portfolio on encapsulation of PV foil which we lack within

Solliance

• Own a production facility that we can leverage for demo-production

Solliance

Translucent Foil

▪ 15

Solliance has the know-how to scale-up the concepts of Sunpartner

onto foil by enhancing the production process of Hyet Solar with

capabilities such as

• Back-end processing for the invisible interconnects

• Nano-imprinting for the micro-patterning

• ALD-barrier technology for the protection

Solliance obviously also develops the know-how to replace the a-Si

aborber with a CIGS or Perovskite-based absorber
