SOLAR POWER

Accurately determine efficiency of perovskite-silicon tandem PV modules

To pave the way for the industrial implementation of highly efficient perovskite-silicon PV modules, the tandem solar cells and modules must be reliably measured. Only then is it possible to make objective comparisons between different cells and modules and to make technological improvements. In contrast to conventional silicon PV modules, however, the calibration is considerably more challenging. A project consortium led by the Fraunhofer Institute for Solar Energy Systems ISE is therefore developing methods for characterizing perovskite-based tandem modules in the "Katana" project, funded by the German Federal Ministry for Economic Affairs and Climate BMWK. The solar simulator specially built for this purpose by the company Wavelabs Solar Metrology Systems GmbH is now in use in the CalLab PV Modules of the research institute.

Renesas samples its first 22-nm microcontroller

Renesas Electronics Corporation has announced that it has produced its first microcontroller (MCU) based on advanced 22-nm process technology. By employing state-of-the-art process technology, Renesas can provide customers with superior performance at lower power consumption driven by reduced core voltages. The advanced process technology also offers the ability to integrate a rich feature set including functions such as RF. Additionally, the advanced process node uses a smaller die area for the same functionality, resulting in smaller chips with higher integration of peripherals and memory.

RENEWABLE ENERGY

Huawei will supply technology to one of the largest RES power plants in Central and Eastern Europe

The largest hybrid farm in Central and Eastern Europe will be built in Poland, combining a photovoltaic and a wind power plants with a total capacity of 205 MW. The annual production will supply electricity to more than 100,000 households and reduce CO2 emissions by nearly 160 tons. To develop the plant's technological infrastructure, Huawei will supply 710 string inverters and 23 smart transformer stations. The hybrid farm is being built on post-mining land in Kleczew, Wielkopolska Voivodeship.
