New way to produce 3D/2D bilayer perovskite solar cells with 24.5% efficiency

US researchers have discovered an appropriate solvent design for the application of a 2D top layer on a perovskite solar cell. The cells incorporate the stability of 2D perovskite cells and the efficiency of 3D cells without destroying the 3D bottom layer, which brings them closer to commercialization.

Solliance hits 30.1% efficiency on perovskite/silicon tandem solar cell

The Solliance consortium achieved a 29.2% record efficiency for the solar cell in November 2021, from just 28.7% in March 2020. In recent months, it increased the perovskite cell for the tandem device from 17.8% to 19.7%.

Perovskite solar module achieves 21.07% efficiency via nanosecond laser tech

Chinese researchers have used inverted perovskite cells with a p-i-n structure to build a perovskite solar module with a reduced heat-affected zone. The panel achieved a power conversion efficiency of 21.07% and a geometric fill factor of 95.5%.

Perovskite quantum dot solar cell with 16.25% efficiency

Chinese researchers have built a perovskite quantum dot solar cell that is reportedly able to reduce trap-assisted charge carrier recombination. The device has an open-circuit voltage of 1.23 V, a short-circuit current density of 17.73 mA cm−2, and a fill factor of 0.745.

Flexible, roll-to-roll printed perovskite solar cell hits 16.7% efficiency

Australian scientists have demonstrated a flexible perovskite solar cell using roll-to-roll compatible “printing” type processes, which could potentially be applied in large-scale manufacturing. Of particular note is the development of a viable roll-to-roll process to deposit the electrode layer, which has thus far been a major challenge. Cells fabricated by the group achieved a maximum efficiency of 16.7%.
