China’s largest PV manufacturers claim limits placed on solar glass production two years ago, to prevent over production, are now causing an industry bottleneck.

In a new paper published in the journal of Renewable and Sustainable Energy, renowned PV scientist Pierre Verlinden examines the solar industry’s trajectory towards the 70 TW of installed capacity that will be needed by 2050, as the best choice for meeting climate targets set out in the 2015 Paris agreement. Silver consumption and recycling, according to Verlinden, will be the biggest challenges in the years to come, as well as ensuring balanced growth and avoiding a major installation rush in the years close to 2050.

Researchers in Spain have analyzed the most important technologies for the development of intermediate-band solar cells (IBSC), a solar PV technology that was conceived to exceed the Shockley–Queisser limit. They identified four established technologies that are currently being adopted to manufacture IB materials and IBSC prototypes. Their future goal is to find the appropriate material to fabricate cheap and very efficient IBSCs.

NREL’s new solar window darkens in the heat of the sun, producing electricity via embedded perovskite film. The tech is based on formamidinium-based metal halide perovskite, an inherently thermochromic material exhibiting significant optical changes.

Researchers in Singapore have developed a 6.4 cm2 solar module based on co-evaporated methylammonium lead iodide (MAPbI3). They claim that the panel is a step forward in the industrialization of perovskite mini-modules.

Leading Edge Equipment Technologies falls in the kerfless solar wafer or direct solar wafer category. Its “drop-in” manufacturing tech cuts wafer costs by 50%, drives up commercial PV power by 7%, and reduces manufacturing emissions by 50%. It’s the emissions piece that may be winning over investors.

A scientist familiar with First Solar’s earlier efforts in CIGS makes the case for the CdTe pioneer to return to the technology.

An international research team has analyzed all existing cooling technologies for PV panels and has indicated the current best options and future trends of research. According to its findings, active water cooling, although expensive and not particularly practical, is the most effective cooling technique while passive cooling systems, despite being easy to apply, have still limited possibilities.

In an update to its International Technology Roadmap for Photovoltaics, the German engineering association the VDMA said that solar module sizes of up to 4.0m² may be brought to mass production in the future.

Netherlands-based technology companies Avy and Wattlab have conducted the first test flight of a drone prototype that is planned to be used in medical projects in Africa.
