Hoshine will invest $2.75 billion in the new polysilicon factory. Elsewhere, Irico New Energy today announced a strategic co-operation agreement with PV manufacturer Jinko Solar that will see it prioritize supply of solar panel glass.

TOPCon solar modules will gain more market share if their average efficiency, already higher than that of PERC panels, continues to improve, according to Stefan Glunz, PV research chief at Germany’s Fraunhofer Institute for Solar Energy Systems ISE. In an upcoming pv magazine webinar on the potential of TOPCon tech, Glunz will show how to reduce costs and increase efficiency.

Scientists in Spain have fabricated a silver bismuth sulfide (AgBiS₂) material with an absorption coefficient that is claimed to be 5-10 times greater than any other material currently used for PV technology. A cell built with these nanocrystals showed a power conversion efficiency of 9.17%, an open-circuit voltage of 0.495V, a short-circuit current of 26.75mA/cm², and a fill factor of 63%.

French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.

The solar panel glass manufacturer expects strong growth in demand for its products at home and abroad with a significant rise expected in the production of PV modules in the USA and Europe.

The triple-junction solar cell is based on indium gallium phosphide (InGaP), gallium arsenide (GaAs), and Germanium (Ge) and is made with a micro-grating made of glass, consisting of a two-dimensional x-framework structure fixed onto the surface of the solar cell. Its operating temperature was found to be 6 degrees Celsius lower than that of a reference cell without the cooling technique.

In other news, Longi raised funds to build another 18 GW of solar cell capacity and Suntech began work on its 10 GW module factory in Anhui Province.

Researchers at the Indian Institute of Technology Delhi have developed solar towers that can be moved from one place to another and can generate 20-30% more power while requiring only 50-60% space compared to conventional mounting setups.

Consisting of a two-dimensional (2D) array of rings and pillars, the structure can improve the short-circuit current of a thin-film crystalline solar cell by over 50%, its creators say. The subwavelength AR structures are robust to certain degrees of fabrication errors, they add.

According to the Silver Institute, global industrial silver demand is expected to grow 8% this year due to strong demand in all key sectors, including the PV industry.
