Multi-junction solar cell integrating radiative cooler
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.
Photovoltaics for multistage flash desalinators
Scientists have investigated how utility-scale solar may be used to power multistage flashing-brine recirculation (MSF-BR) water desalination plants in Aqaba, Jordan. They found the facility would be sufficient to provide the entire city with drinking water. The proposed system configuration comprises a 30 MW solar plant and a standar MSF-BR unit.
Chinese PV Industry Brief: GCL-Poly wants to move to Shanghai Stock Exchange
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.
Portable, space-saving photovoltaic towers
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.
Subwavelength antireflective structure for thin-film solar cells
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.
Latent heat thermal storage with PV for nearly zero-energy buildings
Researchers in Italy are combining PV with latent heat thermal storage (LHTM) and other renewable energy sources to maximize clean energy consumption in buildings. The 47kW PV array and LHTM system work independently, but the scientists said that a heat pump could be used to link them.

Auxin Solar filed the anti-circumvention petition against Vietnam, Malaysia, Thailand, and Cambodia, said an industry note from Philip Shen, managing director at ROTH Capital Partners.
Average silver price expected to drop 1% to $24.80 per ounce this year
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.
Soluna unveils 1.28 kWh portable power generator
Soluna’s new generator can be combined in a two-unit system to reach a capacity of 2.5kWh. It features built-in 120V(AC) output, continuous AC output power of 1,200W, and peak output of up to 2,400W.
Small-area, colored perovskite BIPV module with 13.9% efficiency
Through a conventional coloring technique for crystalline solar modules, scientists in Germany were able to manufacture a colorized small perovskite solar module in white marble optic displays that maintains up to 88.5% of the efficiency it had before coloring. The device was built with five cells interconnected in series and has a total area of 9cm2.
