Perovskites

The module was fabricated with methylammonium lead iodide (MAPbI3) perovskite solar cells via low-cost spin coating. The panel also achieved an open-circuit voltage of 16.07 V, a short-circuit current of 69.52 mA, and a fill factor of 75.35%.

German scientists have developed a perovskite PV cell with remarkable stability by adding a bilayer of polymers that protects the perovskite from corrosion. This design helps to shield the extremely sensitive perovskite interface and provides the cell with extraordinarily high conductivity.

Italian and Iranian researchers have developed the new “deposition via an antisolvent-soaked applicator” technique, which they describe as an easily scalable process to produce uniform, pinhole-free perovskite films. They tested the process on a 6.7%-efficient solar cell based on a polyethylene terephthalate substrate, raising its power conversion efficiency by 82%.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm², they achieved a record efficiency of 25.7% and high operational stability.

Scientists at the Technische Universität Dresden, in Germany, have found that photon recycling and light scattering effects greatly improve light emission in perovskite solar cells, thereby boosting the upper limit for their efficiency to 31.3%.

Lithuanian scientists built the panel with 23.9% efficient solar cells with operational stability of over 1000 h. The module has an active area of 26 cm2.

Developed by a Canadian start-up, Solar Ink can be used to create standalone perovskite solar modules or it can be combined with existing solar modules in a tandem configuration. It can be coated on both flexible and rigid substrates, resulting in translucent solar cells which, in turn, can be used to produce flexible and light modules for application in solar windows and vehicle-integrated photovoltaics.

Developed by scientists in China, the cell achieved an open-circuit voltage of 1.192V, and a fill factor of 80.67%. Its perovskite capping layer was treated with a special ionic liquid that had a positive influence on both the device’s efficiency and stability.

Swedish business Evolar is working on a bolt-on piece of production equipment which would upgrade the cell lines of conventional manufacturers with a perovskite lift in performance.
