Materials that can revolutionize how light is harnessed for solar energy

Scientists have designed organic molecules capable of generating two excitons per photon of light, a process called singlet fission. The excitons can live for much longer than those generated from their inorganic counterparts, which leads to an amplification of electricity generated per photon that is absorbed by a solar cell.

Key factors in how some algae harness solar energy

Scientists have discovered how diatoms — a type of alga that produce 20 percent of the Earth’s oxygen — harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

Mapping the energetic landscape of solar cells

A new spectroscopic method now makes it possible to measure and visualize the energetic landscape inside solar cells based on organic materials. It was developed by a physicist. This novel visualization technique enables scientists to study the physical principles of organic photovoltaics with extreme precision and to better understand processes such as energetic losses.

Treating solar cell materials reveals formation of unexpected microstructures

Hybrid organic-inorganic perovskites have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers, but the surface of hybrid perovskites is prone to surface defects, where charge carriers are trapped in the semiconducting material. To solve this problem, the crystal surface must be passivated. Researchers describe testing hybrid organic-inorganic perovskite crystals treated…

Solar panels cast shade on agriculture in a good way

Combining solar panel (photovoltaic) infrastructure and agriculture creates a mutually beneficial relationship. This practice of co-locating the two by planting crops under the shade of solar panels is called agrivoltaics. Read Full Article Here For more great articles: Solar Energy News — ScienceDaily

Discovery paves way for new generation of solar cells

A new study explains how a promising type of perovskites — human-made crystals that can convert sunlight into electricity — can be stabilized. As a result, the crystals turn black, enabling them to absorb sunlight. This is necessary to be able to use them in new solar panels that are easy to make and highly…

Solar energy becomes biofuel without solar cells

Soon we will be able to replace fossil fuels with a carbon-neutral product created from solar energy, carbon dioxide and water. Researchers have successfully produced microorganisms that can efficiently produce the alcohol butanol using carbon dioxide and solar energy, without needing to use solar cells.
