perovskite solar cell

Researchers in Malaysia have simulated a mixed cation perovskite solar cell integrating tin and germanium in the absorber. By modulating the perovksite layer thickness, they were able to achieve an efficiency ranging from 24.25 % to 31.49 %

A U.S.-based team developed a vapor deposition technique to fabricate outperforming all-inorganic perovskite thin films in under 5 minutes in a continuous process. The adoption of the proposed approach may also result in higher perovskite solar cell power conversion efficiencies.

Researchers in China have fabricated a carbon-based perovskite solar cells that achieves almost the same efficiency as perovskite counterparts based on gold electrodes while also providing higher stability. The novel devices use a playdough-like graphite (PG) electrode that combines the deformable property of carbon paste and the solvent-free property of carbon film.

A German research team has investigated the optical properties of perovskite/perovskite/silicon triple-junction cells and has found these devices may have a practical efficiency potential of 44.3% assuming idealized electrical parameters. These cells may also potentially achieve a fill factor of 90.1%.

Researchers in China have developed a new chemical bath deposition technique to deposit tin oxide on a perovskite cell’s flexible substrate without requiring a strong acid. The resulting cell has achieved a certified efficiency of 24.90% and remarkable stability.

Scientists in Australia claim to have achieved the highest efficiency ever reported to date for a perovskite-CIGS tandem solar cell built on a flexible steel substrate. In the proposed cell configuration, steel can act as both a substrate and an electrode.

Researchers in China claim to have achieved the highest efficiency ever reported for perovskite solar cells based on “alternative” hole transport materials. The device reportedly offers improved hole extraction and significantly reduced charge recombination at the interface between the perovskite layer and the hole transport layer.

Conceived to be produced at substantially lower costs than conventional perovskite solar cells based on metal contacts, the new cell is reportedly able to achieve a bifaciality factor of over 80% and a power generation density exceeding 36%.

Research teams have developed methods for perovskite passivation, but there hasn’t been a clear understanding of how the process works. A new Massachusetts Institute of Technology (MIT) study provides details on how to passivate the material’s surface so the perovskite no longer degrades so rapidly or loses efficiency.

Developed by scientists in Canada, the 0.049 cm2 solar cell was built in ambient air fabricationand with a reactant known as phenyltrimethylammonium chloride (PTACl). It achieved an open-circuit voltage of 0.95 V, a short-circuit current density of 23 mA cm−2, and a fill factor of 80%.
