energySpace Based solar to replace oil using the Nuclear Turbo rocket

Keith Henson has some concerns that high volume flight rates for the SpaceX BFR could be a problem for the atmosphere if it was used for many thousands of flights to place massive amounts of space-based solar power to replace …

energyWorld record for direct solar water-splitting efficiency

Researchers have increased the efficiency of producing hydrogen from direct solar water-splitting to a record 19 percent. They combined a tandem solar cell of III-V semiconductors with a catalyst of rhodium nanoparticles and a crystalline titanium dioxide coating. Teams from …

energyA voltage breakthrough with perovskite solar cells to edge closer to commercialization

A new technique has produced the highest performing inverted perovskite solar cell ever recorded. A team of researchers from Peking University and the Universities of Surrey, Oxford and Cambridge detail a new way to reduce an unwanted process called non-radiative …

energyPerovskite and silicon tandem solar could beat silicon solar in some to many situations

Researchers from EPFL’s Photovoltaics Laboratory and the CSEM PV-center have developed an economically competitive solution to silicon solar cells. They have integrated a perovskite cell directly on top of a standard silicon-based cell, obtaining a record efficiency of 25.2 percent. …

californiaCalifornia requires solar power on all new homes starting in 2020

California has voted to require solar panels on new homes and low-rise apartment buildings built after 2020. The California Energy Commission estimates they would add an average $10,500 in construction costs for a single-family home but generate about $16,000 in …
