Required Number of Rooftops Equipped With Solar Panels to Produce 611,800,000,000 kg of Hydrogen
The first step in this estimation is accessing the Global Solar Atlas; click on the specific location and look for ‘specific photovoltaic power output’, or PVOUT. This estimates the annual productivity of solar panels for a given location, measured in kilowatt-hours generated per kilowatt of peak capacity (kWh/kWp). For purposes … Continue reading
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
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
[google-translator] 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 … Continue reading
