An international research team has defined the operational parameters needed to design and manufacture crystalline silicon PV modules for tropical climates. The group proposed a back-junction, back-contact cell tech with a selective laser soldering technique it claims offers the best potential to yield such robust panels.

The governments of both countries are answering solar industry requests by adjusting tender schemes and considering measures to avoid financial penalties and the loss of incentives due to missed deadlines.

Scientists in China claim to have identified a special cathode material that could be utilized in more stable potassium-ion storage systems. According to the group, this new material could enable the development of storage systems able to retain 94% of their capacity after 2000 cycles, with 0.003% capacity fade per cycle.

A research team in the US has proposed a ‘dual-angle solar harvesting’ method it is claimed could help PV developers optimize energy yield and land use. It is claimed the method would be particularly suitable for projects in cloudier climates and at higher latitudes.

The results of New York Statevs most recent renewable energy request for proposals are in. Some 21 large scale clean energy projects with 1,278 MW of new capacity have been awarded, with 17 of the projects supplying 1,090 MW of solar.

The winners in the Baltic nation’s first clean energy auction will be announced by June 20. With the exercise rated according to the expected output of the facilities allocated, the government has committed to procure 5 GW worth of facilities, from a total 16.3 GW offered by bidders.

Franc Raffalli, president of the Photovoltaic Professions Group of the French Building Federation spoke to pv magazine about the impact of the coronavirus on the French PV industry.

The ‘best conversion performance in the world in a dark room’ is how the developers of a new organic PV device have described it. Such cells could be used as a wireless source of energy for internet of things applications or in gadgets such as temperature-humidity and motion sensors.

Can an organic solar cell material finally be commercialized? Last year, Ubiquitous Energy claimed a world record for efficiency of a “transparent solar cell” with a “certified” 9.8% efficiency.

A footnote in France’s energy legislation had been holding back the development of collective self-consumption in the country, limiting such projects to ‘experimental’ status with terms of no more than five years. The removal of this footnote at the beginning of March means that energy communities for self-consumption are now permitted across the country.
