There is enough solar energy available to cover our global energy needs, but we need better ways of using its full potential. At VTT, we are devoted to helping our clients find new ways of harvesting solar energy, developing solar energy applications and utilising these in their operations.
VTT’s special expertise is the ability to look at solar energy as part of the bigger system.
We are piloting new uses for perovskite solar cells and organic photovoltaics. Printable thin-film solar cells can be used in a wide range of applications.
Integrating solar energy solutions to built environment reduces our dependency on fossil fuels.

Solar energy applications at every scale
We develop technologies for harvesting solar energy, such as organic solar cells and perovskite photovoltaics, and help our clients with planning solar energy systems. Our strength lies in our unique ability to combine practical and theoretical expertise and bring various different players together.
Whether you are optimising solar energy systems or looking to develop energy-autonomous wearable technologies, we have the expertise to support you.
Thin-film solar cells and energy-autonomous IoT
Solar energy and its applications have a lot of untapped potential in the field of digital technologies. Energy harvesting from light could be utilised in energy autonomous applications, for instance wearables, logistics tracking solutions and other smaller-scale sensing with Bluetooth or near-field communication (NFC) features. As trailblazers in printed solar cells and sensor technologies, we conduct cutting edge solar energy research in collaboration with our clients to find new solutions to their needs.
Perovskite solar cells (PSC) and organic photovoltaics (OPV)
Printing and coating technologies enable the fabrication of PSC and OPV with free-form designs without wasting materials or energy. Our lab and pilot facilities offer the perfect space for material testing, device fabrication, characterisation and integration into systems.
Flexible, lightweight and ultrathin solar cells make it possible to harvest energy from light almost everywhere.
Solar energy integration and applications in built environment
On a larger scale, solar energy applications will reduce our dependence on fossil fuels. Distributed energy harvesting will increase the resilience of the energy system and mitigate its vulnerability.
Our wide range of expertise allows us to look at solar energy as part of the bigger system. For example, our system analysis for solar thermal and photovoltaic applications can be used to examine the performance of products integrated into buildings and energy systems.
In hybrid energy systems, solar energy technologies such as concentrated solar power (CSP), building-integrated photovoltaics (BIPV) and solar thermal collectors are connected with, for example, storage systems and building products. These systems can be optimised using our system simulation programs and the performance can be validated by experimental testing and in demonstrations.
Solar-related energy business and services
Developing new service and business models or public policies around solar energy requires a deep understanding of the topic. With our track record of successful national and international solar projects and in-depth solar energy research we have gained thorough knowledge of the opportunities and barriers for solar energy applications.
We help our clients succeed with user studies and stakeholder analyses as well as network and business analyses. What could combining the insights on technology and business do for your organisation?

Here are some of the solar energy field projects VTT is participating in:
The ECOtronics consortium supports the renewal of the Finnish electronics and optics industry and the development of sustainable electronics and optics throughout their lifecycles.
The PerTPV project aimed to drive the performance and fabrication methodologies of high-efficiency, low-cost perovskite solar cells that are compatible with high volume manufacturing.
In the EXCESS project, different solar energy applications are part of Positive Energy Buildings, contributing to the decarbonisation of built environment.
