Researchers from the City University of Hong Kong have developed an all-inorganic perovskite cell with an electron-pair donor which offers a pair of non-bonding electrons. The cell was developed by applying that ‘Lewis base’ small molecule to passivate the inorganic perovskite film.
Chinese scientists have developed a PV floor tile they say is suitable for pavements and cycling tracks. The devices were tested on a ‘green deck’ in Hong Kong. The developers say the tiles have demonstrated satisfactory solar energy conversion, anti-slip performance, heat-resistance and strength.
A mix of higher operating costs and ageing coal assets – plus historically generous solar tariffs – meant the utility banked more profit from the 1.53 TWh of solar electricity it sold in the first half than it did from 25.9 TWh of coal-fired power.
The Singapore-based renewable energy developer has agreed to be sold to investment fund Global Infrastructure Partners. China Investment Corp, Canada’s PSP Investments and other co-investors are also involved in the deal, which is the largest yet seen for the renewable energy industry.
