Modules & Upstream Manufacturing

The office of the U.S. Trade Representative has removed the exemption of bifacial products from Section 201 tariffs, effective October 28.

Researchers from Canada have unveiled a new germanium deposition process which is said to eliminate threading dislocations and be significantly cheaper than previous approaches. The scientists say their technique creates nanovoids on the surface of the germanium layer which can attract and annihilate undesirable dislocations.

An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.

The latest development on the module front sees manufacturers adopting larger wafer sizes in order to reach the industry’s raised expectations for power output. Older “M2” wafers have been the standard in recent years but now appear to be on the way out. Several theories about optimal size are gaining ground, but the future direction of the standard is still far from clear.

Cesium lead black perovskites could be interesting for solar cell development if their crystals are observed in their less efficient but more stable beta phase. The efficiency shortfall can be solved by healing emerging cracks in the surface of the cell using a choline iodide solution, according to an international team of scientists.

The holders of almost six million shares in the company voted against the reappointment of chairman and CEO Liu Hongwei as a non-executive director. On Liu’s watch the company has had to turn to a state bail-out from China to help ensure its survival.

The Norwegian polysilicon and silane gas producer has announced it will listen to offers for its production facility in Butte Montana after mothballing its other manufacturing operation – at Moses Lake, Washington – in the summer.

With the Chinese manufacturer claiming it has already hit 16% conversion efficiency on a large panel, a recent perovskite conference heard predictions the technology will make up the next generation of PV cells – provided it avoids the pitfalls experienced by thin-film devices.

Chinese state-owned PV manufacturer Jetion Solar says it has signed a deal with Italian government-owned oil and gas major Eni to develop a slew of new solar projects across five regions in the next three years in a deal worth €2 billion.

The nation’s plan for grid-parity solar – brought forward to ease a mounting public PV subsidy debt burden – could be left in ruins by a newly-announced scheme to part liberalize the electricity price, itself motivated by a need to bail out financially stricken state-owned power companies.
