Solar Energy As Natural Resource Utilization In Urban Areas
January 1, 2007This research evaluates urban areas’ potential to utilize rooftop solar cells as power plants. They are environmental-friendly and potentially viable electrical generators.
Moisture Resistance In Perovskite Solar Cells Attributed To A Water-Splitting Layer
January 4, 2021Researchers showed that the engineering of a hole extraction layer with possible water-splitting additives could be a viable strategy to reduce the impact of moisture in perovskite devices.
Moisture-Tolerant 3D Perovskite Solar Cells
September 23, 2021Researchers studied three different alkyl chain length organic cation-based 2D perovskite coatings for 3D perovskites. The 2D perovskite incorporated solar cells showed significant improvement in solar cell stability with limited compromise in solar cell efficiency. The longest alkyl chain length sample showed only a 20% drop in power … Continue reading
Progress Of Perovskite Solar Cells: 29% Efficient 2020-2021
July 7, 2021This review summarizes the main progress of Perovskite Solar Cells (PSCs) in 2020 and 2021 from the aspects of efficiency, stability, perovskite-based tandem devices, and lead-free PSCs.
Germany’s Artificial Sun to Produce Hydrogen
June 5, 2021 A research facility in North Rhine-Westphalia, Germany, has built Synlight, an artificial sun intended to develop production processes for solar fuels, including hydrogen. The system consists of 149 Xenon short-arc lamps focused on an area of 20 x 20 centimeters in a 3-story building. Synlight’s 350-kilowatt array … Continue reading
Farm in Desert Uses Saltwater and Sun Only
October 6, 2016 A farm in Australia is now using seawater and sun to grow vegetables, and it does not require pesticides or fossil fuels. Instead, it relies on a sun-powered desalination plant and a greenhouse to irrigate tomatoes. This is of course a great step forward along the lines … Continue reading
Solar Cell Triggered by Sun and Rain
April 11,2016 A study published in Angewandte Chemie has found that when combined with an electron-enriched graphene electrode, a dye-sensitized solar cell can be excited by incident light on sunny days and raindrops on rainy days. Its optimal solar-to-electric conversion efficiency is 6.53%.
Highly Efficient Solar Cells
March 27, 2016 A new study published on March 24, 2016 in the journal Science demonstrates that hybrid lead halide provskites, solar cells that can be produced cheaply with easily synthesized materials, have an astonishing ability: not only do they absorb energy from the sun to generate electricity as all … Continue reading
1st Prototype: Electricity From Solar, Sewater and Gravity -No fossil fuels or Fission
February 10, 2016 We are pleased to note that the first large-scale project to generate electricity around the clock using solar energy, seawater and gravity is now under construction in the Atacama Desert in northern Chile. While it bears some similarities to the design we have long recommended, it does … Continue reading
