Model agreement to make solar and wind share same connection point in the Netherlands

The model agreement was outlined by Dutch consultancy Ventolines B.V. and follows the introduction of new provisions for the sharing of the same connection point issued by the country’s government last year.

Heterojunction design for 26%-efficient copper bismuth oxide thin-film solar cell

Researchers in Bangladesh have simulated a solar cell based on a copper bismuth oxide material, used as an absorber, with n-type cadmium sulfide (CdS) utilized as a buffer layer. In the experiment, the device achieved an efficiency of 26.0%, an open-circuit voltage of 0.97 V, a short-circuit current density of 31.61 milliampere per square centimeter, and a fill factor of 84.58%.

First Solar claims lowest module degradation rate in the industry

The US cadmium telluride thin-film module maker said its Series 6 CuRe panels are able to retain 92% of its performance at the end of the 30-year warranty. The improved stability of the product was achieved by eliminating copper and placing Group V elements such as antimony or arsenic onto the tellurium crystal sites.

Green hydrogen and the cable-pipeline dilemma

New research from Singapore has found that gas pipelines for the onshore transport of green hydrogen and the cables for the transport of electricity to produce it at a distant location have similar costs at a 4000 km transmission distance. For longer distances, gas pipelines were found to be cheaper than cables, although the electric lines are said to benefit from scaling up and higher utilization. For both options, however, a currently too high hydrogen LCOE remains the biggest barrier to overcome.

Amorphous silicon solar cells still niche market

In the second interview of a series, Arvind Shah, a professor at École polytechnique fédérale de Lausanne, told pv magazine about the challenges facing amorphous silicon cells. He said the tech could be used in some window applications and greenhouses, but not in rooftop projects, as the stabilised efficiency of these cells is too low.

Trina launches tracking system for high-power modules

The tracker has a length of 72 meters, which the company says allows for 120 modules per tracker. The new product was conceived as a multi-drive, dual-slewing system that is claimed to have improved overall stability compared to other products and to show a reduced aeroelastic effect.

Solar cell with transparent passivate contact achieves 23.99% efficiency

German scientists have built a solar cell with ultra-thin transparent layers that are claimed to be effective in preventing recombination events. The technology, which has the potential of achieving efficiencies close to 26%, may be easily scaled up for commercial production, according to the researchers.

New compressed air storage tech from Canada

Canadian compressed air storage specialist Hydrostor said that projects built with its technology have a capex range of between $175 and $250/kWh. The company secured C$4 million ($3.19 million) in funds from Natural Resources Canada’s Energy Innovation Program and Sustainable Development Technology Canada to pursue the development of its global pipeline.

I’ve got solar over my skin

Researchers in Japan have built a PV-powered device to measure volumetric variations in blood circulation. The system, which is just a few microns thick, was built with an organic solar module, a polymer light-emitting diode (PLED), and an organic photodetector.

5N Plus enters space solar cell business with acquisition of Azur Space

The purchase price should range between €73 million and €79 million. Azur Space produces triple-junction space solar cells with an average efficiency of up to 30% and is planning to develop ultra-thin solar cells with up to 35%.
