A new method for quantifying crystal semiconductor efficiency
23 Aug 2019 at 6:48am
Scientists have found a new way to successfully detect the efficiency of crystal semiconductors.
Materials that can revolutionize how light is harnessed for solar energy
19 Aug 2019 at 8:27am
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.
Organic dye in zinc oxide interlayer stabilizes and boosts the performance of...

Organic solar cells are made of cheap and abundant materials, but their efficiency and stability still lag behind those of silicon-based solar cells. A team of scientists has found a way to enhance the electric conductivity of organic solar cells, which increases their performances. Doping the metal oxide interlayer, which connected the electrode and active layer, with a modified organic dye boosted both the efficiency and stability, the study revealed.

Key factors in how some algae harness solar energy
13 Aug 2019 at 10:42am
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
13 Aug 2019 at 7:19am
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.
New perovskite material shows early promise as an alternative to silicon
8 Aug 2019 at 12:24pm
CsPbI3 is an inorganic perovskite, a group of materials gaining popularity in the solar world due to their high efficiency and low cost. This configuration is noteworthy as stabilizing these materials has historically been a challenge.
Installing solar panels on agricultural lands maximizes their efficiency
8 Aug 2019 at 9:38am
A new study finds that if less than 1% of agricultural land was converted to solar panels, it would be sufficient to fulfill global electric energy demand.
Method to automatically estimate rooftop solar potential
7 Aug 2019 at 4:08pm
The progress of rooftop solar installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one, say scientists. Now researchers are proposing a new, data-driven approach that uses machine learning techniques and widely available satellite images to identify roofs that have the most potential to produce cost-effective solar power.
In the future, this electricity-free tech could help cool buildings in metrop...
5 Aug 2019 at 8:21am
Engineers designed a new system to help cool buildings in crowded metropolitan areas without consuming electricity, an important innovation as cities work to adapt to climate change. The system consists of an inexpensive polymer/aluminum film that's installed inside a box at the bottom of a specially designed solar 'shelter.' The film helps keep its surroundings cool by absorbing heat from the air inside the box and transmitting that energy into outer space.
Treating solar cell materials reveals formation of unexpected microstructures
30 Jul 2019 at 9:03am
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 with benzylamine to investigate the mechanisms by which the surface of the crystal is passivated, and traps states are reduced.
Ultra-thin layers of rust generate electricity from flowing water
30 Jul 2019 at 6:26am
Researchers have shown that iron oxide layers can convert kinetic energy of saltwater into electrical power.
Solar panels cast shade on agriculture in a good way
29 Jul 2019 at 9:37am
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.
'Deforming' solar cells could be clue to improved efficiency
29 Jul 2019 at 8:12am
Solar cells and light sensing technologies could be made more efficient by taking advantage of an unusual property due to deformations and defects in their structures.
A good first step toward nontoxic solar cells
