Recyclable, back-contact solar panel from the Netherlands

Conceived by a Dutch consortium, according to Design for Recycling guidelines, the panel is being developed with two different encapsulants, one for the front of the module, which joins the glass and cells together; and a slightly different formulation for the back of the module, which attaches cells and backsheet together.

Storing solar power with compressed carbon dioxide

An Italian company has developed a system that can store energy from wind, solar and grid electricity by compressing and using CO2 without any emissions. The system draws CO2 from an inflatable atmospheric gas holder, stores it, and uses it to produce power again, when demand for stored energy arises.

Defining BIPV

Incorporating solar into our built environments represents an opportunity for hundreds of gigawatts to be installed worldwide without taking up any additional land. In many cases though, this will require solutions beyond typical rooftop PV installations and much closer cooperation between the PV and construction industries. A new report published by IEA PVPS looks to bring together the interests of both worlds, and clearly categorize both the building envelope and energy functions of different BIPV components.

U.S. decarbonization goals hinge on scaling up heterojunction cell tech

HJT technology could fill an innovation gap in the residential and commercial rooftop PV market, and boost U.S. solar leadership through domestic manufacturing of cells and modules.

Puffer fish inspired floating PV structure

With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

Record solar numbers expected this year but IEA highlights pricing concern

The Paris-based body expects the world will have installed almost 160 GW of solar this year, a record number, but still not enough to keep the prospect of a net zero global economy by mid century in sight.

Photovoltaic rotary energy system for domestic applications, high-rise buildings

Developed by scientists in Turkey, a system prototype has operated at lower PV module temperatures and removed most of the dust accumulation. The researchers are now planning to improve the device by applying MPPT converter topologies.

The long read: Cloud looms over PV’s silver lining

Should heterojunction solar technologies be temporarily shelved? Could copper plating replace screen-printed silver conductive surfaces in cells? Why are tandem cells a likely successor to PERC? Brett Hallam recently sat down with Natalie Filatoff in Sydney to explain the findings of a new study by UNSW that sought to answer these controversial questions.

Mounting system for rooftop PV relying on large-size solar modules

Developed by Spanish manufacturer Alusín Solar, the new mounting system is claimed to be, currently, the only one on the market that provides six fixing points for a solar panel in ballast-secured structures.
