Screen-printed electrode for further development of perovskite solar modules

Emerging Photovoltaic Technologies

In the research topic Emerging Photovoltaic Technologies, our work focuses on the following fields of work:

 

Dye and Perovskite Solar Cells

 

Organic Solar Cells

 

Photon Management

 

Tandem Solar Cells on Crystalline Silicon

At Fraunhofer ISE research is performed on Emerging Photovoltaic Technologies: dye and perovskite solar cells, organic solar cells, photon management as well as tandem solar cells on crystalline silicon. With these new technologies, we aim to open up new potential for optimization in photovoltaics and thus reduce electricity generation costs.

This includes increasing the efficiency of conventional solar cells made of crystalline silicon using advanced photon management to improve the absorption and reflection properties.

Approaches using alternative processes and materials are also part of our work. Dye and organic solar cells, for example, have lower efficiencies than conventional cells yet are much cheaper to manufacture. Our research in organic solar cells focuses on the fundamental properties of selective contacts. We are investigating the realization of contacts that are extremely thin and made of cost-effective starting materials which remain stable over a long period of time. Together with industry partners, Fraunhofer ISE develops stable coating and encapsulation processes on their in-house roll-to-roll coating unit.

In our research on perovskite solar cells, we are working to improve the stability. Our long-standing experience with upscaling dye solar modules serves us well here.

Tandem silicon solar cells enable us to use the solar spectrum more effectively by reducing the thermalization losses.  We at Fraunhofer ISE are researching different sub-cell concepts for these solar cells.
