Triple junction perovskite cell hits 16.8% efficiency
Scientists in the Netherlands fabricated three different perovskite layers, all using the same process. The three cells are all tuned to different bandgaps in order to absorb different wavelengths of light. A triple-junction device incorporating all three achieved 16.8% conversion efficiency. This, the researchers say, is a promising result for the technology, though would require the development of new wide-bandgap perovskites to push much further.
Engie EPS deploys ‘power-to-power’ hydrogen-based storage solution

Fraunhofer to develop battery inverter for whole-area UPS and renewables integration
Industrial and academic partners are developing a battery inverter which can be grid connected under normal operation but can also use nearby renewables generators to form an island grid, for whole-area uninterrupted power supply.
Meyer Burger, CSEM to develop new PV cells, modules
Meyer Burger has extended its seven-year tie-up with the Swiss Center for Electronics and Microtechnology by three years. They aim to achieve module-level production efficiencies of more than 24%, while also cutting costs.

France launches tenders for hydrogen projects
The French authorities have launched two tenders for projects, in line with a new national plan to develop carbon-free hydrogen, announced Sept. 8.
Huge solar carport for Disneyland Paris
A new 17 MW solar array is expected to cover around 17% of the theme park’s electricity needs. Completion is scheduled for 2023.
Bayesian algorithm to reduce LCOE of bifacial projects
German researchers have proposed a new model, based on a range of parameters, to influence the LCOE of bifacial PV plants, with a focus on components, land costs, inclination angles, albedo, and weather conditions.
Sustainable aircraft fuel will need a lot more renewables capacity
A research paper into the prospects of manufacturing ‘power-to-liquid’ kerosene in Germany has concluded the government will end up importing it. Wherever the world’s clean aviation fuels are made, however, it seems a lot of clean power will be needed to drive the production process.
