Imec hits 27.1% efficiency with its new perovskite-silicon tandem PV cell

Imec, the leading research and innovation hub in nanoelectronics, energy and digital technology, within the partnership of EnergyVille, announced a record result for its 4-terminal perovskite/silicon tandem photovoltaic cell. In fact, with a reported power conversion efficiency of 27.1%, the new tandem cell tops the most efficient standalone silicon solar cell. Further careful engineering of the Perovskite material will bring efficiencies over 30% in reach.

Imec’s new record tandem cell uses a 0.13 cm² spin-coated perovskite cell developed within the Solliance cooperation, stacked on top of a 4 cm² industrial interdigitated back-contact (IBC) silicon cell in a 4-terminal configuration, which is known to have a higher annual energy yield compared to a 2-terminal configuration. Additionally, scaling up the tandem device by using a 4 cm2 perovskite module on a 4 cm2 IBC silicon cell, a tandem efficiency of 25.3% was achieved, surpassing the stand-alone efficiency of the silicon cell.

Solliance sets 14.5% cell performance record on large perovskite PV modules

Solliance announced a new record stabilized average cell performance of 14.5% for its large thin-film perovskite photovoltaic modules on glass. The efficiency was measured on an aperture area of 144 cm2.

The perovskite module was realized on a commercial 6x6 inch2 glass substrate, a size comparable to standard commercial silicon solar cells. The substrate is provided with a transparent conductor, by applying three consecutive slot die coating processes and using a newly developed annealing process. The metal top electrode was evaporated. Twenty-four cells were series-connected through optimized laser-based scribes. Up to 95.3% of the modules area is covered with active material, resulting in a stabilized module efficiency of 13.8%.

Solliance and ECN make great strides in improving tandem solar cells

The recent Silicon PV/nPV conference in Lausanne, Switzerland, saw Solliance's announcement on the achievement of a major milestone in perovskite technology for application in future industrial high efficiency tandem photovoltaic cells and modules. Solliance announced realizing a perovskite cell that combines good cell efficiency with a very high near infrared transparency of 93%.

Also at the conference, ECN shows that when this perovskite cell is mechanically stacked on a 6 inch2 silicon bottom cell with its proprietary MWT-SHJ (metal-wrap-through silicon heterojunction) design, 26.3% efficiency is achieved, an increase of 3.6% points over the efficiency of the directly illuminated silicon cell laminate.

Solliance achieves a new efficiency record for perovskite-based PV technology

Solliance has achieved a new world record for Perovskite Solar Cell technology demonstrated on industrially applicable Roll-to-Roll (R2R) processes of 13.5% conversion efficiency at cell level. The group stressed that the records were achieved in a factory setting, using an industrially scalable process.

Solliance has achieved the conversion efficiency of 13.5% and module-level aperture area conversion efficiency of 12.2% for perovskite-based photovoltaics using industrially-applicable, roll-to-roll production processes. By further optimizing and re-validating processes that were earlier developed buy Solliance, the performance at both the cell and module level have been improved.

Imec and Solliance create perovskite PV modules with 12.4% efficiency

Imec, a leading research and innovation hub in nano electronics, energy and digital technologies, and partner in Solliance, announced that it has improved its 4x4cm² perovskite module achieving a certified conversion efficiency of 12.4%.

The module efficiency was measured under long-term maximum power point (MPP) tracking, testifying to its exceptional stability. At Solliance, this perovskite technology is developed with industrially-applicable processes and with a view towards a rapid market introduction of this promising source of renewable energy.
