Carbon-based, HTL-free perovskite solar cells with 26% efficiency

An international research team has designed a carbon-based perovskite solar cell without a hole transport layer. Two plasmonic nanoparticles – Ag@SiO2 and SiO2@Ag@SiO2 – were added to the cell photoactive layer, in addition to a copper(I) thiocyanate (CuSCN) interlayer at the perovskite-carbon interface.

Chinese manufacturer wants 28%-plus efficient HJT perovskite tandem solar cells

Footwear producer Golden Solar announced it would enter the solar market last year, with a focus on heterojunction devices.

Formamidinium-cesium perovskite solar cell with 24.25% efficiency

Developed by scientists in China, the cell was used to fabricate a 20.5%-efficient mini perovskite module. A dual-functional additive was applied to regulate the crystallization and defects of the formamidinium-cesium perovskite film.

Tin perovskite solar cell with operational stability of over 1,300h

Scientists in Spain have built a 10.61%-efficient tin perovskite solar cell with improved open-circuit voltage and stability. The device was fabricated with formamidinium tin iodide (FASnI<sub3), sodium borohydride (NaBH4) as a reducing agent, and a bulky secondary ammonium cation of small size known as dipropylammonium iodide (DipI).

ZSW selects vacuum coating machine from Singulus Technologies for the further development of contact layers for perovskite solar cells

Singulus Technologies has received a new order from the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) for the delivery of a VISTARIS sputtering system for the further development work for perovskite solar cells.

Double-junction perovskite-tin sulfide PV cell design with up to 28.92% efficiency

An Iranian-Italian research group has simulated a double-junction tandem solar cell based on perovskite and tin sulfide. They said that it can reach an efficiency rating of between 22.9% and 28.92%.

Hanwha Q Cells, Helmholtz-Zentrum Berlin claim 28.7% efficiency for 2T perovskite-silicon tandem solar cell

The Korean manufacturer and the German research center were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.

Spectrum splitters to raise efficiency of perovskite-silicon tandem solar cells

Researchers in Canada have conducted a series of simulations to understand how spectrum splitters may raise the efficiency of two-terminal tandem solar cells and have found that efficiency gains may be of up to 6%. The proposed cell configuration was also found to be economically competitive.

Semi-transparent perovskite solar cell with 13% efficiency, 27% transparency

Developed for applications in BIPV, vehicle-integrated solar and smart glasses, the solar cell was built with an ultra-thin, semi-transparent, triple-cation perovskite film and gold nanorods (Au NRs). The device achieved an open-circuit voltage of 1097.1mV, a short-circuit current of 17.11mA/cm2 and a fill factor of 73.12%.

Mini perovskite solar module with 40 sq cm aperture area, 17% efficiency

The 19.2%-efficient perovskite cells used in the module rely on an electron layer based on tin oxide that was deposited via chemical bath deposition. This technique, according to the device’s creators, has made it possible to have a relatively small drop in efficiency from small cells to the 40cm2 module.
