New Generation Of Efficient Solar Cell Technology Breakthrough

- Jan 17, 2017 -

´╗┐The seventh EU research framework programme (FP7) to provide 3 million euros, the total R & D investment of 4 million euros, to support the 6 members of the EU and associated countries Italy, Spain, Germany, Britain, Sweden and Switzerland interdisciplinary science and technology personnel in Europe GLOBASOL research team. From the beginning of March 2013, long-term commitment to the development of a new generation of efficient solar cell technology.

The GLOBASOL research team determined the technical development route is to maximize the absorption of solar radiation by using full spectrum light, not only need to improve solar photovoltaic conversion efficiency to improve the conversion efficiency of solar radiation. Absorbing material is the key to improve the full spectrum of solar light heat into electricity efficiency, scientific research team to take the "two step" strategy, the development of organic or organic dyes based on full metal and quasi solid dielectric innovative sensitized solar cell (SMSCs) mesoscopic materials. SMSCs can efficiently absorb solar radiation light within 750 nm wavelength, the nano crystallization technology, also known as quantum dots, efficient absorption of solar radiation light wavelengths of 750-1100 nm. Photonic gap structure design innovative magnification of the solar infrared and near infrared spectral absorption, designed solar cell series top arrangement, help to absorb the most transparent low-energy photon solar radiation light.

For the solar radiation wavelengths above 1100 nm, the research team mainly adopts the latest development of thermoelectric nanowires and nano crystalline and amorphous alloy based on the combination of conversion materials, maintain the best performance 500-700's temperature range.

Two kinds of adding lead iodide and methyl ammonium iodide mixed with new materials, to achieve the natural formation of the crystalline structure of material symmetry. A new generation of highly efficient solar cell prototype hybrid photovoltaic and thermoelectric materials technology development, the conversion efficiency of solar energy currently has more than 28%, creating a new world record.more high quality solar battery at SNL company, including:
