Metal halide perovskites are characterized by low-cost, high photoluminescence quantum yield, and high color purity. In recent years, perovskite light-emitting diodes are developing fast, with promising applications in lighting and display fields. However, the ubiquitous thermal-induced fluorescence quenching in perovskite emitters lacks systematic research, and methods to suppress thermal quenching need to be further […]
Geothermal energy has long been the forgotten member of the clean energy family, overshadowed by relatively cheap solar and wind power, despite its proven potential. But that may soon change – for an unexpected reason. Geothermal technologies are on the verge of unlocking vast quantities of lithium from naturally occurring hot brines […]
Lithium-ion batteries, fuel cells and many other devices depend on the high mobility of ions in order to work properly. But there a large number of obstacles to such mobility. A research team led by Jennifer L. M. Rupp of the Technical University of Munich (TUM) and Harry L. Tuller of the Massachusetts Institute […]
Materials scientists at the UCLA Samueli School of Engineering and colleagues from five other universities around the world have discovered the major reason why perovskite solar cells – which show great promise for improved energy-conversion efficiency – degrade in sunlight, causing their performance to suffer over time. The team successfully demonstrated a simple manufacturing […]
What are the advantages and disadvantages of solar cooker Class 10? Quality of Solar Cooking Good price. Unlike an LPG -based cooking solution where you need to spend money every time you get a new fuel, a life -saving cooker does not require a fee. constant. … Environment. … Food, sweets and hygiene cooking. … […]
When it comes to building the future of energy in Africa, the decisions facing the continent’s leaders today are nothing less than of historical importance. More than anything else, energy systems are the very fabric of business and society. Countries across Africa want to make good on their objective of building huge amounts of […]
