Scientists in the United Kingdom have proposed for the first time to deposit silver nanoparticles in electron transport layers used in perovskite solar cells to improve device performance. They found that an “optimal” concentration of silver nanoparticles may help to improve a perovskite cell’s charge transfer and extraction, as well as its efficiency.
Researchers at the Jülich Research Center in Germany have used novel photoluminescence measurements to analyze the recombination of charge carriers in perovskite solar cells. They have found that the loss of charge carriers in perovskite devices works differently from other types of PV cells.
Researchers at RMIT University’s School of Science, Monash University and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have harnessed artificial intelligence to accelerate the design and production of perovskite solar cells.
A group of scientists in Korea has a hot-air technique instead of atomic layer deposition to fabricate a perovskite absorber that reportedly shows a higher film quality. They applied this film in a perovskite-organic tandem solar cell, which exhibited low open-circuit voltage losses and high efficiency levels.
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.
An international group of scientists has fabricated an inverted perovskite solar cell that claims both high power conversion efficiency and a promising high degree of stability. A champion cell achieved a power conversion efficiency of 25.3%, with an encapsulated version retaining 95% of the initial efficiency after extensive heat and humidity testing.
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%.
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.
The research team said the cell also achieved remarkable thermal stability, as it was able to retain 90% of its original efficiency for over 1,000 h. The device uses a self-assembled monolayer to stabilize the interface between the perovskite absorber and the hole transport layer.
