Scientists from Purdue University claim to have created a new material that incorporates both organic and inorganic materials. Its hybrid structure is said to improve the thermal stability of perovskite PV cells without the need to use lead.
Researchers at the Massachusetts Institute of Technology have developed a transparent coating they successfully incorporated into a perovskite solar cell, increasing efficiency and stability. The group says with further improvements the material could be used as a simpler, less expensive alternative to widely used indium tin oxide as a transparent conductive material for a range of applications.
An international research group achieved the result on a 9 sq mm, triple-cation based, n-i-p structured perovskite cell using low solar concentration levels. Device instability, however, remains a challenge.
An international research group claims to have developed a new bulk perovskite semiconductor material that can capture the excess energy of hot electrons. The material is said to rapidly absorb as heat energy which would otherwise be wasted. With the harvesting of hot electrons, the maximum theoretical efficiency for hybrid-perovskite solar cells could increase from 33% to 66%.
Research from Canada has revealed liquid-like lineshape dynamics in cesium-lead iodide perovskite nanocrystals. The findings could be used to produce cheaper and more efficient perovskite cells, researchers claim.
A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.
The Swiss solar equipment supplier today fought off an attempt by its largest single shareholder to have a representative appointed to its board and to have its executive pay regime reviewed. Victory in that battle may secure the company some wiggle room, but the war over corporate strategy appears far from over.
A U.S. research team has used protein bacteriorhodopsin to improve the efficiency of what it called ‘bioperovskite’ solar cells. The scientists used Förster Resonance Energy Transfer to predict the strength of long-range excitonic transport between the perovskite and protein layers.
The four-year-old Hangzhou-based business says it already has a 20 MW perovskite module pilot line and is working on a mass production facility in the city of Quzhou.
The Swiss equipment maker has announced a fresh, CHF18 million order from Oxford PV but the news may have been strategically timed ahead of today’s update that it has completed the sale of its headquarters building.
