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.

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

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.

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).

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%.

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.

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.

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%.

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.
