The research team found that sodium, contrary to common belief, does not decrease per se indium and gallium interdiffusion, while instead hindering intergrain diffusion by segregating at grain boundaries.
Alexander Schönfeldt of energy storage specialists Younicos examines the growing trend of energy storage-as-a-service, and explains why the sector is growing at such a rate.
Austria’s largest power provider announced a plan to invest around €100 million in solar and €15 million in recharge stations for electric vehicles over the next five years. The company aims at investing mainly in residential and C&I projects.
The Dutch solar fair has now taken the shape of an international event, due to the increasing number of big players attracted to the Netherland’s PV market, and the high level of professionalization that has now been reached by the local ecosystem of installers and distributors. Although a few uncertainties on the possible changes of the current regulatory framework are suggesting caution, solar across all of its segments is clearly set to become a mainstream source of energy nationwide.
The Swiss PV equipment manufacturer recorded a loss of about €68 million last year. Although Meyer Burger was able to slightly increase sales, the EBITDA margin was below 3%. This year, the company is aiming for an EBITDA margin of 10% percent in order to return to profitability.
Investments in new large-scale solar energy projects in Spain are expected to surpass €4 billion over the next two years. Meanwhile, the regional government of Castilla-La Mancha is planning to reduce the time frame for the authorization process for solar and renewables from 12 to 9 months.
European solar research organization Solliance and the Energy Research Center of the Netherlands (ECN) have announced the achievement of 26.3% efficiency on a transparent perovskite solar cell combined with a crystalline silicon solar cell.
Scientists led by Cambridge University have discovered that adding a simple solution of potassium to the ink solution has the effect of ‘healing’ defects in metal-halide perovskite films, and immobilizing ion movement. This, according to the researchers, could push the material to higher efficiencies, while also increasing its stability.
Scheme’s goal is the reset the Finnish capital’s carbon neutrality target date from to 2035 by ramping up renewable energy use, electric vehicle adoption and energy-efficiency upgrades.
