Main tasks attributed in the project

Tasks of EPFL:

EPFL will be involved mainly in WP2, of which it is WP leader, WP3, WP4 and WP5. Main activities foreseen are the following:

  • Profiting from the high open circuit photo-voltage output of the PSC (Voc > 1.2 V) we aim at reaching a PCE of 6 % from 80% transparent PSC top layer alone.

  • Development of new perovskite compositions to reach 5 % PCE with near UV absorbing PSC device that produces a Voc of at least 1.8 V

  • Fabrication of high efficiency DSC devices using NIR dyes and monitoring their stability.

  • Development of new metal oxide scaffolds for PSCs and DSCs.

Development of new transparent redox electrolytes.

Profile of EPFL:

EPFL is an established world leader for dye- and perovskite-sensitized solar cells having pioneered both solar cells concepts. This is documented by high-impact publications throughout the years as well as a dedicated effort towards certifying device performances on a regular basis (which make EPFL the only European lab to certify perovskite solar cells). Based on this expertise, EPFL has an ideal profile to fulfil the above tasks:

  • EPFL demonstrated that the small and oxidation-stable Rb+ cation can be embedded into a “cation cascade” to create a perovskite material capable of achieving efficiencies up to 21.6% with a record open– circuit voltages of 1.24 V. Importantly, these materials passed the stringent endurance tests being exposed simultaneously to full sun light and 85 °C for 500 h while operating at their maximum power point. EPFL has not optimized these compounds fully

  • It is currently very challenging to increase the perovskite thickness without losing film quality. EPFL has developed expertise to handle the perovskite material including thickness variations. Already some if the highest currents are reported at EPFL at therefore it is reasonable that this can be pushed to the theoretical limit in the future.

  • Similar to the multication approach, EPFL has the expertise to screen, characterize and assess complex material group. This includes especially perovskite materials that are only varied through the metal positions. However, this knowledge can be extended towards perovskite-like materials as well where expertise is required to develop the material and to translate it towards a high throughput of devices

  • EPFL has recently developed a new method for depositing this wide band semiconductor in the form of thin films. EPFL identified the reason for its notorious instability and succeeded in solving the problem by introducing a separation layer between the CuSCN and the back contact. This led to PSCs showing a PCE over 20 % and excellent stability both under long term heat stress at 85 °C and prolonged light soaking. Since the parameter space for sample development is very large, the optimization procedures need to be supported by predictive methods which will allow to focus solar cell test series only on promising preparation formulations.
