Single-junction transparent perovskite solar cell achieves record-breaking voltage of 1.78 V
A research team in Germany claims to have achieved the highest open-circuit voltage ever recorded to date for a perovskite solar cell based on hybrid methylamine lead chloride (MAPbCl3). The novel perovskite absorber was fabricated with a two-step deposition method and annealing under molecular nitrogen (N2) gas inside a glovebox.
Weekend Read: Thin prospects
The production of PV ingots and wafers remains the most highly concentrated of all the production stages in the silicon solar supply chain. Yet efforts to re-establish production in Europe and the United States are not for the faint-hearted.
Chinese PV Industry Brief: Daqo reports revenue drop due to lower selling prices
Daqo increased polysilicon production volume in 2023 to 197,831 MT, representing a 47.8% year-over-year increase compared to 133,812 MT produced in 2022.
Italian startup offers roll-to-roll process for organic solar panels
Ribes Tech, a spinoff of the Italian Institute of Technology, has established a roll-to-roll process to produce organic photovoltaic modules that it says can be expanded to enable volume production of PV modules for indoor sensors, trackers, and electronic devices.
Sunova Solar announces 9 GW cell factory in China
Sunova Solar’s new cell manufacturing facility produces 182 mm, 199 mm and 210 mm TOPCon cells. At full capacity, the facility is expected to produce approximately 36,000 high-efficiency modules per day.
Scientists describe anti-soiling performance mechanisms in solar glass
Laboratory and outdoor soiling experiments conducted in Saudi Arabia have shown that increased particle resuspension by wind is one of the dominant factors for high anti-soiling performance in photovoltaic glass.
Photovoltaics for refrigerated warehouses
Scientists in China have analyzed the performance of PV-driven refrigeration warehouses and have found they can ensure stable operation thanks to a refrigeration coefficient of performance of up to 2.66.
Pneumatic PV facade with solar trackers
A group of researchers in Germany has designed a novel PV façade using two actuators that allow bending in two directions. The PV functionalization of FlectoSol aims for an energy self-sufficient shading system.
MIT research provides roadmap to perovskite passivation
Research teams have developed methods for perovskite passivation, but there hasn’t been a clear understanding of how the process works. A new Massachusetts Institute of Technology (MIT) study provides details on how to passivate the material’s surface so the perovskite no longer degrades so rapidly or loses efficiency.
New copper antimony sulphide solar cell design promises 16.17% efficiency
A group of researchers has made another attempt to design solar cells based on non-toxic and earth-abundant copper antimony sulfide. The proposed cell architecture is the result of the optimization of the device’s layer thicknessess.
