Modules & Upstream Manufacturing

The Directive No. 2022/542 was published in the Official Journal of the European Union on April 5. According to the new provisions, member states will be free to apply a VAT rate of 0% to 5%.

Conceived by a German start-up, the system is claimed to achieve a 75% efficiency in converting direct radiation into heat. It may be either equipped with solar trackers or photovoltaic modules, which would both occupy the same space on the front and lateral sides of the installations.

The US manufacturer secured this week two solar module supply deals from Origis Energy and Silicon Ranch, respectively.

Researchers have developed a PV module with with an efficiency of 20.72%, based on tin oxide (SnO2) as an electron transport layer,  an organometal halide perovskite layer, organic halide salt phenethylammonium iodide (PEAI) as a passivation agent, and Spiro-OMeTAD as the hole transport layer (HTL).

A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.

While Europe was previously a leader in the manufacturing of solar cells and modules, the plans falling into place this year already represent a scale never before seen on the continent. And they’ll need that scale if Europe is to meet expected demand for new solar over the coming decades, without relying heavily on imported products and components. Many of the technologies at the center of these plans are brand new as well; pv magazine looks at a few of the innovators planning to scale up alongside more mainstream players, and how these fit into plans for a fully fledged European PV supply chain.

Scientists in Canada fabricated a perovskite solar cell based on an inverted structure that achieved 23.9% efficiency, and maintained 92% of its initial performance after 500 hours of accelerated aging tests. By carefully controlling the thickness of the perovskite layer, the group was also able to gain control of “quantum mechanics” properties such as the movement of electrons within the layer and the wavelengths of light absorbed.

In other news, Shuangliang is planning to set up 20 GW of solar module production and Longi has said higher electricity prices may have an impact on its financial results.

Chinese manufacturer BYD has opened a new manufacturing line at its factory in Campinas, Brazil. It will use the new line to produce PV modules with a power outputs ranging from 450 W to 670 W.

The Genap Energy Cover uses HyET Solar Powerfoil thin-film solar modules, rated at 12.0% efficiency, for agricultural water storage and reservoirs, with an initial focus on the greenhouse and horticulture markets in the Netherlands. Genap said a 12kWp test setup had a generation density of 60W/m2, rising to 120W/m2 within a year, with an eventual target of 165W/m2.
