Modules & Upstream Manufacturing

The plant will produce super-high-efficiency heterojunction solar cell modules for residential and commercial applications.

Developed by a German group of scientists, the panels are considered an ideal solution for aesthetically demanding applications in buildings with stone facades. Although their power yield is more than halved compared to conventional modules, the modules can also be used as partial shading walls or semi-transparent roof elements.

The sky is the limit. Fortunately, this expression does not apply to current prices for PV panels, which have recently declined, following a continuous rise since the beginning of the year. Whether this situation holds, or whether prices drop further in the coming months is hard to say at the moment, writes Martin Schachinger of pvXchange. Polysilicon prices and thus wafer and cell prices could be in for a slight decline. However, a decisive movement in module prices in general is unlikely before the fourth quarter.

South Korean scientists have developed a novel coating that purportedly reduces average cell reflectance and significantly increases short-circuit current. The coating is based on aluminum oxide and indium tin oxide.

Auto glass producer Asahi India Glass and polymer packaging specialist Vishakha have revealed plans to jointly set up India’s largest solar glass plant in the state of Gujarat. The factory will initially have a capacity equivalent to 3 GW of solar installations per year.

Xinte’s parent company – TBEA – has agreed to buy new shares issued by the company for RMB2.3 billion and these funds will be used to implement its 100,000 MT expansion plan. Furthermore, EVA solar film manufacturer Bbetter Century and 8 GW factory in the Shaanxi Province.

The Munich-based chemical company was also able to significantly increase sales volumes for its polysilicon segment. In June, Wacker Chemie raised its forecast for the full year substantially.

Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.

Developed by Chinese researchers, the novel design methodology consists of utilizing metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. According to its creators, it ensures a farmer’s average income increases by 5.14 times, including the solar power generation business. A system built with this approach should cost around €715 per kW installed.

Developed by a Vietnamese-Korean research group, the complex PV device was built with a bottom bifacial crystalline silicon perovskite-filtered heterojunction sub-cell that is able to absorb all solar spectra in the short-wavelength range.
