Researchers develop perovskite-based bird-eye-inspired camera for enhanced object detection

Researchers from Gwangju Institute of Science and Technology (GIST) and Institute for Basic Science (IBS) have developed a perovskite-based camera, inspired by the structures and functions of birds' eyes, specializing in object detection.

The eyes of different organisms in the natural world have evolved and been optimized to suit their habitat and the environment in which they survive. As a result of countless years of evolutionary adaptation to the environment of living and flying at high altitudes, bird eyes also have unique structures and visual functions. In the retina of an animal's eye, there is a small pit called the fovea that refracts the light entering the eye. Unlike the shallow foveae found in human eyes, bird eyes have deep central foveae, which refract the incoming light to a large extent. The region of the highest cone density lies within the foveae, allowing the birds to clearly perceive distant objects through magnification. This specialized vision is known as foveated vision.

Researchers address the challenges of proton-conducting perovskites for next-generation fuel cells

Protonic ceramic fuel cells (PCFCs) have attracted much attention lately. These devices do not operate via the conduction of oxide ions (O2−) but light protons (H+) with smaller valence. A key feature of PCFCs is their ability to function at low and intermediate temperatures in the range of 50–500 °C. However, PCFCs based on perovskite electrolytes reported thus far suffer from low proton conductivity at low and intermediate temperatures.

A research team, led by Professor Masamoto Yashima from Tokyo Institute of Technology (Tokyo Tech), in collaboration with High Energy Accelerator Research Organization (KEK), has set out to address this limitation of perovskite-based proton conductors.

Renshine plans GW-scale perovskite PV panel factory

It was reported that Renshine Solar will open a gigawatt-scale perovskite PV module factory in Jiangsu province, with a planned investment of CNY 1 billion ($138 million). 

The CNY 1 billion gigawatt-scale perovskite cell project will be located in the Economic and Technological Development Zone (ETDZ) in Changshu, Jiangsu province, China. The Company started operating a 150 MW production line for perovskite modules in January. It has since claimed that its commercial modules have achieved a power conversion efficiency of 18.4%.

Researchers set efficiency record for stable multipodal self-assembled molecule-based perovskite solar cell

Researchers at the Chinese Academy of Sciences (CAS), in collaboration with Japan's Yamagata University, developed three isomeric bisphosphonate-anchored self-assembled molecules (SAMs) to achieve highly efficient and stable inverted perovskite solar cells (PSCs).

The wettability, absorbability and compactness of SAMs, which are used as hole-transporting layers (HTLs) for PSCs, critically affect the efficiency and stability of the devices. Therefore, the researchers proposed a molecular strategy to synthesize three bisphosphonate-anchored indolocarbazole (IDCz)-derived SAMs, namely IDCz-1, IDCz-2, and IDCz-3. The three SAMs with different positions of the two nitrogen atoms in the IDCz unit were each employed on conductive oxide substrates for inverted PSCs.

Researchers develop thermal regulation strategy to improve stability and efficiency in all-perovskite tandem solar cells

Researchers at China's Qingdao University of Science and Technology and Canada's University of Toronto have developed a thermal regulation strategy by incorporating carboranes into perovskites to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. 

The Chinese-Canadian research group has designed a monolithic all-perovskite tandem solar cell that utilizes a top inverted perovskite PV device based on an absorber made with mixed tin-lead (Sn-Pb) perovskite via the newly developed thermal regulation strategy.

Empa and ETH researchers are working to improve cameras with perovskite image sensors

Empa and ETH Zurich researchers are working to develop image sensors made of perovskite that could deliver true-color photos even in poor lighting conditions. Unlike conventional image sensors, where the pixels for red, green and blue lie next to each other in a grid, perovskite pixels can be stacked, thus greatly increasing the amount of light each individual pixel can capture.

A consortium comprising Maksym Kovalenko from Empa's Thin Films and Photovoltaics laboratory, Ivan Shorubalko from Empa's Transport at Nanoscale Interfaces laboratory, as well as ETH Zurich researchers Taekwang Jang and Sergii Yakunin, is working on an image sensor made of perovskite capable of capturing considerably more light than its silicon counterpart.

Researchers develop strategy based on SAMs to design inverted PSC with 24.38% efficiency

Researchers from China's Hangzhou Dianzi University and Jiaxing University have developed a strategy for optimizing the bottom region of perovskite solar cells and designed an inverted perovskite solar cell using the new strategy. 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.

“The HTLs prepared with SAM materials not only have negligible parasitic absorption, low material consumption, and stable adhesion but also exhibit inherent passivation of defects on the bottom of perovskites,” the research team explained.
