Current market and industry status
Current PV industry challenges – relevant policies challenges
OPV focus from our participation to the EU funded Cheetah project –
refer mostly to the current challenges for market uptake, main
standardization needs, preliminary cost assessment (if ready). Here it
would also be interesting to see your views on those topics and maybe
we could establish some fruitful synergies between the two projects.
Over the last couple of years, the global research community has been
experiencing an OPV boom, nowadays triggering a fast growing interest in
industry in this young and disruptive technology, since OPV devices enable
various new applications that cannot be served by classical silicon solar cells. In
particular, OPV open up new opportunities for design in architecture, e.g. the
integration of solar cells into facades, overhead glazing or windows. Major
challenges associated with bringing organic PV to the market are: Increasing the
power conversion efficiency, reducing the production costs and increasing the
material and device long-time stability. A key to meet all those objectives is the
utilization of environmentally friendly (“green”) synthesis of materials and green
deposition techniques, since only green synthesis allows to go to large scale
material and device fabrication. MatHero is designed to tweak all those key
parameters in order to enable devices with a power conversion efficiency
exceeding 10%, a cost reduction below 0.5 €/Wp and a life-time of more than 10
years by developing disruptive green synthesis and fabrication techniques.

breakthrough
Over the last couple of years, the global research community has been
experiencing an OPV boom, nowadays triggering a fast growing interest in
industry in this young and disruptive technology. In particular, OPV open up new
opportunities for design in architecture, e.g. the integration of solar cells into
facades, overhead glazings or windows. Major challenges associated with bringing
organic photovoltaics to the market are: Increasing the power conversion
efficiency, reducing the production costs and increasing the material and device
long-time stability. To increase the general performance of large scale roll-to-roll
processed OPVs it is necessary to develop polymers and polymerization methods
that allows for large scale production of high efficiency materials at a relatively
low cost. It will be presented that even though it is possible to produce large
quantities of high performance materials using traditional batch synthesis,
problems such as variability from synthesis to synthesis leads to batch-to-batch
variations in the molecular weight distribution which is a very influential
parameter for most polymer systems in terms of delivering uniform high
efficiency OPVs.
If the solar cell market is dominated more than 90% by silicon technology, the
organic / inorganic composites are called to prevail where it shows superior
performances versus silicon technology. The application of new materials in the
manufacture of the different components of a photovoltaic module: electrodes,
active layer, electron transport layer (ETL) and hole transport layer (HTL) is
therefore growing. This emphases the importance to work on R&D of these
different materials and then focus on their industrialization in order to meet the
expected growing market demand. Genes'Ink is positioned as the leader in the
development and industrialization of charge transport layers and electrodes for
OPV devices.

Title of presentation: The Next Great Leap
Forward in Power Technology - To be
powered by OPV
A comprehensive overview of the concept “green” (i.e. environmentally friendly)
applied to OPV inks will be carried out. Environmentally friendly technologies
related to the synthesis of OPV materials, components of ink formulations,
printing/coating technologies and drying/curing processing will be summarized.
Different strategies to design, prepare and apply effective, stable and reproducible
OPV green inks will be pointed out. The particular HSP approach for OPV green
ink formulation involved in MatHero project will be explained and discussed.
Finally, the main trends and challenges in OPV green inks will be presented.
Solar power is gradually becoming cost-competitive with traditional mainstream
energy sources such as oil and coal, but to achieve this still requires significant
further reductions in the costs of materials, manufacturing, and installation. OPVs
holds the promise of addressing these issues owing to their potential to be massproduced at high speeds via solution printing processes on lightweight substrates
like plastics, but still require further increases in efficiency and operational lifetime
to be genuinely cost-competitive with traditional energy sources. Nevertheless,
the properties unique to OPVs – such as the lightweight, flexibility, optically semitransparent and high performance in indoor light energy harvesting has never
cease attracting commercial interests particularly in portable electronics, power
source for IOTs as well as OPV’s designable factor has made them perfectly
suited for use in architectural or other design areas, such as windows, building
facades, aesthetic internal buildings or cars, where other energy technologies are
infeasible.

Title of presentation: Printable thin film
encapsulation for organic photovoltaic
protection
Using non-halogenated solvents to process polymer solar cells is of pivotal
importance for the transfer of lab-scale processes to an environmentally friendly
and sustainable industrial fabrication. Here, we present xylene: anisaldehyde as
the processing solvent of photoactive layers. By using the additive anisaldehyde,
the morphology can be tweaked as effectively as compared to the commonly
used diiodooctane, additionally benefitting from a much faster drying. Several high
performing polymers: fullerene blend systems are cast from this non-halogenated
solvent mixture, thereby exceeding overall power conversion efficiencies of 10%.
Due to a rapid degradation upon oxygen and water ingress, organic photovoltaic
(OPV) devices need to be encapsulated with gas-barrier materials to ensure long
lifetime. In the MatHero project, Arkema and CEA develop a thin film
encapsulation process, consisting of the direct deposition of the gas barriers on
the OPV device in a fully printable way. Such barriers are optimized in terms of
oxygen and water permeation rates and compatibility with the device. The
objective is to outperform the usual gas-barrier film lamination process while at
the same time allowing low cost encapsulation.

Title of presentation: Solution Processed
OPV – From Development to Commercial
Opportunities
Eight19 has been developing solution processed Organic Photovoltaic (OPV)
modules since being founded in 2010. The company is now engaging with
customers to develop OPV products based around specific needs and
specifications. Photovoltaic modules based on organic semiconductors open up a
new way of highly efficient manufacturing employing roll-to-roll coating and
printing processes. The flexibility, robustness and non-toxicity of the materials
make them suitable for a wide range of off-grid applications. Tailoring the energy
levels of the donor-acceptor system to the respective light source enables the
creation of energy harvesting solutions for various applications, both outdoor and
indoor. With the emergence of the internet of things, there is an increasing
demand for energy autonomous operation of systems without the need to
replace batteries. In addition, recent developments at Eight19 have shown that
Organic Photovoltaic (OPV) modules show remarkably good performance under
low light conditions when benchmarked against other PV technologies modules
show remarkably good performance under low light conditions.

Title of presentation: Towards new trends in
the Building Integrated Photovoltaic Market:
BI-OPV
Building Integrated Photovoltaic (BIPV) systems consist of solar photovoltaic
cells and modules that are integrated as part of the building envelope, replacing
conventional building materials. Currently, the majority of photovoltaic
production is first-generation, based on silicon wafers including single crystal (cSi) and multi-crystalline silicon (mc-Si). These devices are reliable and durable,
but half of the costs is the silicon wafer and efficiencies are limited to around
20%. Third PV generation is potentially capable of overcoming the efficienc limits
for single band-gap solar cells, also adding a fast manufacturing process with even
less material usage.Thus, in order to take advantage of the third PV generation
on the BIPV market and within the framework of the European 7FP project
ArtESun, ONYX seeks to demonstrate the feasibility of using OPV modules in
BIPV applications. Within this project, efficient organic solar cells with an
increased lifetime and a decreased production cost which can be used in many
other non-BIPV related final applications, such as RFID “Radio Frequency
Identification” or Antennas with OPV integration will be developed.
