Not long ago, Germany's Q-Cells company developed a new solar PV module, it’s conversion rate is high as 17.84%；output power is up to 268 watts.
Q-Cells solar modules by 60 highly efficient 156 × 156mm2 polysilicon formed. 1.492 m2 in the face of the test machine produces high efficiency of 17.84%. The new record has been (European Solar Test Installation) indeed confirmed.
Main difference between the substrate in the component back through the nano-layer metallization and passivation process, thereby improving the conversion efficiency. (Source: http://www.q-cells.com)

Presently, the conversion efficiency rate of solar photovoltaic modules is about 13% to 17% micro. Germany Q-Cells conversion rate is bound to cause a new development of new technologies on the market, but the unit cost of power generation currently innocence new data.
