If you want to search for optimal data of solar photovoltaic cells, it is best to full light can be "absorbed" rather than "launch light. However, researchers at nanyang technological university in Singapore have found both absorption and emission of light material! The main composition of the material, is the perovskite (Perovskit, researchers say its potential is widely applied.
Absorb sunlight, perovskite have show a lot of success. A prototype of graphene photoelectric equipment its staggering 15.6% efficiency. But he found that the material can "light", the team was accidentally discovered"
Although most of the pv data specializes in absorb light, but it only perovskite materials by laser irradiation can "light up"
At the time, physicists SunTzeChien let postdoctoral student XingGuichuan use laser to illuminate his development of a new hybrid perovskite pv data, then miracle happened like this. Sum, assistant professor, said the found a high quality material, very durable, not only can capture light particles and converted into electricity, also can use in turn. By adjusting the composition information, also can let it spread out wide area color, so it will also apply to as a graphic display of luminous element"

The material can absorb light in broad daylight, and at night "release"
In addition, due to the perovskite can be made into translucent, so it can also be placed in the bottom of the screen, so that the mobile device through the "natural way" charging under the sun.
Of course, the data also can directly provide display device in the night "backlight" and "light up" screen. If again a bit bigger scale, perovskite materials may also be lase even good material.
From school of information engineering college (MSE and the energy research institute (ERI @ NripanMathew, assistant professor of N said: so versatile General information, and low cost will be a green building in areas such as the Gospel"
The research team has applied for patent solar photovoltaic cells for the material, its details Scienc journal has been published in science.
