An international team of scientists fabricated perovskite solar cells which retained almost all of their initial 21% efficiency after 1,000 hours under continuous operation at their maximum power point. The researchers credit this performance to their discovery of an additive that served to ‘block’ ions that cause device degradation, and also hope their work will contribute to an improved understanding of the relationship between efficiency and stability in perovskite PV.

The 2.2 MW vertical solar plant, built on a dam wall at an altitude of almost 2,500 meters above the sea level, is expected to be commissioned within four months.

A Swiss start-up has created a containerized movable PV system that is designed to be easily relocated to allow the use of solar energy in locations where a fixed installation is not an option. The solution is based on a racking technology which can include two racks able to host up to 30 solar panels.

In the third interview of a series, pv magazine spoke to Prof. Arvind Shah of École polytechnique fédérale de Lausanne and Associate Prof. Alessandro Romeo from the University of Verona about the challenges and opportunities of cadmium telluride (CdTe) PV tech. They said there is still potential to ramp up efficiency and cut costs, and claimed that the toxicity of cadmium should not be seen as a serious concern.

The Swiss federal government has also decided to improve the bureaucratic procedures for the installation of solar PV systems.

Hydrogen and hydrogen-based fuels will not be able to move forward fast enough to replace fossil fuels and tackle climate change, according to a German-Swiss research team that claims direct electrification alternatives are cheaper and easier to implement. The scientists cite too-high prices, short-term scarcity and long-term uncertainty, as the main reasons for their skepticism.

The proposed solution is claimed to be able to mitigate potential fire risk, improve logistics and reduce costs. It consists of a series of interchangeable wide blocks that are said to be easily movable for simplified transportation.

The solar module will be available in three versions – white, black, and glass-glass. The products have an output of up to 400 W, but when the bifacial effect is optimally used, the output of the glass-glass module can reach up to 430 W. Both the white and black modules weigh less than 20 kg

Before the official start of production, the Swiss photovoltaic manufacturer signed contracts with several suppliers that only use polysilicon produced by Wacker Chemie. Meyer Burger plans to start producing its solar modules and cells in Germany in the second quarter.
