The China National Institute of Metrology has certified the result. The manufacturer claims it was able to increase the panel efficiency from 16.02% to 18.04% in a few months.

A group of international researchers has developed a new perovskite-silicon solar cell design using a top perovskite PV device with an energy bandgap of 1.67 eV and a new self-assembly monolayer based on carbazole. The tandem cell achieved a higher efficiency compared to counterparts without the monolayer and passed the IEC 61215 standard thermal cycling test.

The Chinese Academy of Sciences has unveiled a high-efficiency perovskite solar cell with a purported peak efficiency rating of 26.1%, by using 1-(Phenylsulfonyl)pyrrole (PSP) as an additive. The cell is third-party certified with an efficiency of 25.2%, and it maintains 92% of its original efficiency after 2,500 hours of operation.

Bangladeshi scientists have developed a high-efficiency perovskite solar cell with 26.96% efficiency, an open-circuit voltage of 1.0478 V, and a fill factor of 81.35%.

Researchers in Italy have used protective buffer layers in perovskite solar cells to mitigate damage during the sputtering of indium tin oxide in the production process. They claim the buffer layers were able to fulfill this mission without impairing the cell’s average visible transmittance.

Iranian researchers have improved perovskite solar cell efficiency by using a single-walled carbon nanotube as a hole transport layer surrounded by lead sulfide colloidal quantum dots.

Scientists in India have fabricated indoor bifacial perovskite solar cells that purportedly achieve remarkable power output per single cell. The devices also reached a bifaciality factor of 0.73.

Researchers in Iran have designed a new light trapping (LT) structure for perovskite solar cells that reportedly achieves optimal light absorption without impacting the electrical properties of the cells. The key element of the device is an anti-reflector layer based on silicon dioxide (SiO2) that improves light harvesting and charge extraction performance.

Scientists in China have built a tandem bifacial mesoscopic perovskite solar cell via a new passivation strategy. The cell achieved an improved power output and voltage, and the researchers said it offers potential applications in practical usage.

With perovskite PV technology showing promise for next-generation solar manufacturers, LED steady-state solar simulators have the flexibility to provide perovskite developers with the measurement accuracy required.
