Perovskite solar cell reaches record efficiency
Hybrid materials could smash the solar efficiency ceiling
(Phys.org) —A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells.
Researchers use liquid inks to create better solar cells
(Phys.org) —The basic function of solar cells is to harvest sunlight and turn it into electricity. Thus, it is critically important that the film that collects the light on the surface of the cell is designed ...
LEDs made from 'wonder material' perovskite
(Phys.org) —Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.
Big beats bolster solar cell efficiency
(Phys.org) —Playing pop and rock music improves the performance of solar cells, according to new research from scientists at Queen Mary University of London and Imperial College London.
Creating simpler, cheaper solar cells
Over the last four years, solar cells made from materials called perovskites have reached efficiencies that other technologies took decades to achieve, but until recently no-one quite knew why.
Organic solar cells more efficient with molecules face-to-face
(Phys.org) —New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor ...
A promising light source for optoelectronic chips can be tuned to different frequencies
Chips that use light, rather than electricity, to move data would consume much less power—and energy efficiency is a growing concern as chips' transistor counts rise.
