Researchers at have now mapped how energy flows in organic solar cells, something that previously had been unknown. Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Scientists advance renewable hydrogen production method

Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and…

Solar beats nuclear at many potential settlement sites on Mars

While most missions to the moon and other planets rely upon solar power, scientists have assumed that any extended surface mission involving humans would require a more reliable source of energy: nuclear power. Improvements in photovoltaics are upending this calculus. A new study concludes that a solar power system would weigh less than a nuclear…

Converting solar energy to electricity on demand

A new energy system that makes it possible to capture solar energy, store it for up to eighteen years and release it when and where it is needed has now taken the system a step further. After previously demonstrating how the energy can be extracted as heat, they have now succeeded in getting the system…

Solar cell keeps working long after sun sets

Researchers have constructed a photovoltaic cell that harvests energy from the environment during the day and night, making use of the heat leaking from Earth back into space. At night, solar cells radiate and lose heat to the sky, reaching temperatures a few degrees below the ambient air. The device under development uses a thermoelectric…

Solar hydrogen: Better photoelectrodes through flash heating

Producing low-cost metal-oxide thin films with high electronic quality for solar water splitting is not an easy task. Especially since quality improvements of the upper metal oxide thin films need thermal processing at high temperatures, which would melt the underlying glass substrate. Now, a team has solved this dilemma: A high intensity and rapid light…

Scientists achieve record efficiency for ultra-thin solar panels

A team has successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometer thick, convert light into electricity more efficiently than others as thin and pave the way to make it easier to general more clean, green energy.

Materials scientists finding solutions to biggest hurdle for solar cell technology

Materials scientists 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 adjustment to fix the cause of the degradation, clearing the biggest hurdle toward the widespread adoption of…

Predicting solar cell performance from terahertz and microwave spectroscopy

Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of…

These solar panels pull in water vapor to grow crops in the desert

Using a unique hydrogel, scientists have created a solar-driven system that successfully grows spinach by using water drawn from the air while producing electricity. The proof-of-concept design offers a sustainable, low-cost strategy to improve food and water security for people living in dry-climate regions.
