Resumo/Summary:

Perovskite solar cells (PSC) technology is ideally placed to meet the growing demand for energy production from renewable sources. PSCs should have a lower cost than traditional silicon technology and the fact that they have high energy efficiency and they can be produced with various patterns and colors allow its use in BIPV. Several efforts have been devoted for obtaining PSC devices with very high energy performance, but little attention has been devoted to the study of more technological aspects, though essential for a future industrial production. To transform PSCs into a marketable product there are then several critical challenges that have to be addressed. Thus, WinPSC project proposes the encapsulation of PSCs using a disruptive process of hermetic sealing assisted by laser. This new process should allow the PSCs to have a lifetime of 20 years. WinPSC project also responds to the development of an ohmic contact based on graphene that allow the production of semitransparent devices. The development of high electrical conductivity substrates is essential for the production of efficient devices and also with a higher useful area; sub-modules consisting of strip PSC cells not only is not an aesthetically pleasing approach, as it has high costs. The WinPSC project proposes the development of substrates incorporating metallic lines for efficient collection of the electricity generated. Finally, the possibility of coupling PSCs with thermoelectrics devices will be also studied. The main objective of this project is the development of a 10 × 10 cm2 device with efficiency ≥12 % and stability > 500 h, which will be used to demonstrate the scalability of the developments that allow to produce the first solar module perovskite with 20 years of lifetime.
