Imec makes steady progress on Perovskite PV modules reaching a record 11% PCE

imec believes that ultimately it should be possible to achieve a power conversion efficiencies of more than 20% for this type of thin-film solar cell

13 Jul 2015 | Editor

imec has announced at ITF US (San Francisco, July 13, 2015), a record 11.3% aperture and 11.9% active area efficiency for its thin-film perovskite photovoltaic (PV) module. The efficiency was measured over an aperture area of 16cm2. This achievement is the best conversion efficiency for perovskite modules in literature.

According to the announcement Imec’s perovskite module achieves a geometrical fill factor of more than 95% and an aperture conversion efficiency of 11.3%. The active area efficiency was demonstrated with 11.9%.

These "record" devices have been fabricated by the conventional lab scale spin coating process.

Imec also used a linear coating technique (blade coating) for all the solution based layers, to prove industrially viable fabrication methods. By using this method, the modules achieved a 9% aperture area efficiency.

imec is exploring stacking a perovskite cell on top of a silicon solar cell to increase the conversion efficiency of silicon solar cells. The perovskite cell will capture the light which is not absorbed by silicon, as such enabling conversion efficiencies of more than 30%.

Imec is developing a platform for glass-based perovskite modules in collaboration with Solliance.

There is growing interest in both glass-based and thin-film perovskite PV technology for the BIPV market.

Tom Aernouts, R&D manager for thin-film photovoltaics at imec, said, "Imec is steadily improving the conversion efficiencies of its perovskite solar cells and at the same time adjusting the fabrication processes to enable industrial adoption of this promising technology." Tom added, "Leveraging our expertise in organic photovoltaics enables us to make rapid progress in enhancing the conversion efficiencies, ultimately aiming at conversion efficiencies of more than 20% for this type of thin-film solar cells."
