Perovskites

The Japanese industrial technology supplier is shipping coating tools for perovskite solar panels with dimensions up to 1,000 mm × 2,000 mm. The company will also offer soon a support for 2,400 mm ×1,200 mm sizes.

Researchers in China have designed an inverted perovskite solar cell with a new strategy aimed to optimize the cell’s bottom region. The proposed cell was treated with two molecules known as 2-mercaptoimidazole and 2-mercaptobenzimidazole and was based on a hole transport layer relying on a self-assembled monolayer.

Researchers in China have outlined a new surface engineering strategy to build low-cost solar cells without a hole transport layer. The devices were treated with benzoylcholine halide to reduce non-radiation recombination and achieved remarkable efficiency and stability.

Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.

The researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.

An international research team developed a perovskite solar cell performance-boosting treatment based on phenethyl ammonium chloride (PEACl) that is also claimed to reduce the number of process steps. With this technique, the group built a champion device with a 20.9% efficiency.

Developed through bandgap engineering and material design, the proposed PV device relies on a tin-based perovskite material known as CsSnI3-xBrx. It can reportedly be further designed to achieve power conversion efficiencies exceeding 24%.

An international research group has developed a solar cell based on a lead-free perovskite material known as Cs2AgBiBr6. The cell’s absorber was doped with trans-polyacetylene, which reportedly helped the device to improve its efficiency by more than 20%.

An international research team has developed a new type of perovskite solar cell by using 4-phenyl thiosemicarbazide (4PTSC) as a precursor additive. The device showed an improved open-circuit voltage and “exceptional” long-term stability.

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 %
