Weekend read: the fruitful search for other thin films

First Solar and its cadmium telluride (CdTe) technology dominate thin-film solar in the mainstream market. Valerie Thompson looks at the US-based business and the future of thin-film PV technology.

Perovskite-silicon tandem tech tested in solar race car

A team of Dutch university students under the banner Top Dutch Solar Racing has installed perovskite silicon tandem cells in its entry in the 16th edition of Bridgestone World Solar Challenge. The upcoming race is a six-day, 3,000km expedition across Australia, from Darwin to Adelaide.

New method to take PV plant measurements in the field

Spanish researchers claim to have established new measurement methods to assess the performance degradation of PV modules without the need for removing and reinstalling the tested PV modules from their operating positions. The new approach is claimed to increase productivity in PV plant quality control activities.

Swedish startup to use green hydrogen plasma in pilot reactor for solar grade silicon

Encouraged by lab results and a feasibility study, Swedish startup, Green14, in collaboration with Sweden’s Royal Institute of Technology (KTH) plans to build a pilot-scale reactor to make solar grade silicon with a hydrogen plasma process. The company sees the pilot as a step towards using a more sustainable method to produce solar grade silicon for the PV industry at its own gigawatt-scale plant.

Low-temperature processes to reduce silver use in tandem perovskite-silicon solar cells

Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallisation and module interconnection.

Toshiba claims 16.6% efficiency for polymer film-based large-area perovskite solar module

Japanese electronics giant, Toshiba, is continuing to improve the performance of its perovskite solar cell technology.

CATL unveils EV battery enabling 400km driving range on 10-minute charge

Chinese battery industry heavyweight Contemporary Amperex Technology has unveiled a new electric vehicle battery that reportedly enables long-range driving on a fast, 10-minute charge. It expects mass production to begin by the end of this year, and vehicles equipped with the battery to be available in the first quarter of 2024.

Weekend Read: Mapping a path to tandem commercialisation

Chris Case, chief technology officer for Oxford PV, recently spoke with pv magazine about the U.K.-based company’s new 28.6%-efficient, commercial-sized, tandem solar cell, its U.S. subsidiary, and plans for the future.


Study finds growing inequality in metal footprints of renewable power value chains

An international research group has investigated the flow of iron, copper, aluminium, and other precious metals from source to end-use destination in the renewable energy infrastructure value chain. It found significant imbalances that can be attributed to the continuous outsourcing of metal demand for the renewable power sector to developing economies.

SEG Solar plans 5 GW cell, 3 GW module production plant in Indonesia

United States-headquartered module maker SEG Solar has leased land in Indonesia where it will establish a 5 GW capacity solar cell and 3 GW capacity PV module manufacturing facility.
