Amorphous silicon solar cells still niche market
In the second interview of a series, Arvind Shah, a professor at École polytechnique fédérale de Lausanne, told pv magazine about the challenges facing amorphous silicon cells. He said the tech could be used in some window applications and greenhouses, but not in rooftop projects, as the stabilized efficiency of these cells is too low.
I’ve got solar over my skin
Researchers in Japan have built a PV-powered device to measure volumetric variations in blood circulation. The system, which is just a few microns thick, was built with an organic solar module, a polymer light-emitting diode (PLED), and an organic photodetector.
5N Plus enters space solar cell business with acquisition of Azur Space
The purchase price should range between €73 million and €79 million. Azur Space produces triple-junction space solar cells with an average efficiency of up to 30% and is planning to develop ultra-thin solar cells with up to 35%.
Low outdoor degradation for 20.76%-efficient solar cells made of UMG silicon
Spanish manufacturer Aurinka has tested the degradation rate of its 20.76%-efficient solar cells made of 100% upgraded metallurgical grade (UMG) silicon and has found it shows the same values as conventional polysilicon. The company is currently building a UMG factory in northern Spain.
Debate on alleged forced labor in Chinese PV industry heats up in the Netherlands
Three Dutch political parties have brought the forced labor issue to Parliament and have asked the Minister for Foreign Trade and Development Cooperation, Sigrid Kaad, to report on the matter.
Noise-based technique to test crystalline silicon solar cells
The proposed technique is said to be able to connect directly to the microscopic and medium scale defects in the solar cell materials. It is based on three kinds of noises that science has thus far been able to identify in PV devices.
Chinese PV Industry Brief: Another big polysilicon deal and rising wafer prices
Risen will sell 50,000 metric tons of poly to Shangji Automation and Zhonghuan Semiconductor has raised the prices of all its wafer products.
Perovskite solar cell with larger grain size and 23.17% efficiency
The result was achieved for a small area device with the size of 0.1 sq cm. The cell was fabricated with a Tin(IV) oxide electron transport layer modified with crystalline polymeric carbon nitrides (cPCN).
Hair! Coming to a next-generation PV cell near you
Scientists have found that a human hair derivative can protect, stabilize and enhance the performance of perovskite solar cells.
Jinko shipped 18.7 GW of modules in 2020
The Chinese module manufacturer saw its net profit rise only slightly last year, despite a larger increase in turnover and shipments. It expects to almost double its shipments to up to 30 GW of PV modules in the current fiscal year.
