An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.

Scientists led by the Technical University of Denmark have begun a project to design solar cells that can be produced in different colors with minimal effect on performance, making them suitable for building-integrated and other applications with aesthetic considerations.

The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.

New Zealand begins negotiations with four other small nations on trade agreement to remove tariffs on environmental goods, such as solar PV, and eliminate fossil fuel subsidies. The deal would be a world’s first, and another example of the confidence boost New Zealand enjoys during the Rugby World Cup.

The global expansion of PV, wind power and other clean energies will see double-digit growth this year as solar continues to lead the pack.

A report by Germany’s Energy Watch Group thinktank has said we would be better off sticking to coal and oil than switching to gas because emissions of methane, the most potent greenhouse gas, caused by gas extraction render any related carbon savings irrelevant.

It took a while, but now the energy giants can finalize the mega deal. Rival energy companies have criticized approval of the deal amid fears Eon could dominate the German market.

Credibility comes not just from offering products that generate clean electricity, but also from the way in which those products are manufactured, says SMA Solar Technology CEO Jürgen Reinert. Here, transparency and sustainability are key. That’s why one of the world’s largest PV inverter producers has partnered with pv magazine’s UP sustainability initiative. In the following Q&A, Reinert lays out what SMA is doing to step UP its green game.

On the first day of this year’s EU PVSEC conference, Adelaide-based veteran solar researcher Pierre J Verlinden won the Becquerel Prize for Outstanding Merits in Photovoltaics. The award recognized more than 40 years as a leading PV researcher in academia and at leading companies including Sunpower and Trina Solar. Its recipient, now a board member of Australian solar technology provider BT Imaging, spoke to pv magazine about what is needed from solar to stave off catastrophic climate change.

The invention converts the energy produced by PV cells directly into mechanical motion without the need for batteries or power electronics. Its developers claim the robustness of the solar motor can drive water pumps and ventilation turbines for more than 20 years without the need for maintenance.
