‘If the emission cone can be narrowed to more closely match the absorption cone of incoming sunlight, which is exactly what our work demonstrates experimentally, solar cells will, in principle, be able to approach efficiencies close to 43%’

eurekalert.orgSolar cells gain efficiency by emitting light in fewer directionsICFO researchers have increased the power conversion efficiency of organic solar cells by restricting the angles at which they emit light. The strategy, presented in Energy & Environmental Science...

‘key to narrowing the emission cone is the use of a metal as the front electrode…layered structure surrounds this silver-based electrode to form, together with the silver electrode at the back of the cell…makes it possible to combine broad-angle reflectivity, which effectively narrows the emission’
