New antenna for a better photon harvest
An Italian research team has developed a device that it says can easily be integrated into a PV cell, and can boost its efficiency by converting more light particles into a high energy state before they are absorbed by the cell. The scientists claim that their innovation could offer a green‐to‐blue photon upconversion yield as high as 15%.
Huawei facing another three SolarEdge lawsuits
Inverter manufacturer SolarEdge has filed three additional patent infringement lawsuits against its competitor, Huawei, in China. This comes after three similar legal actions against Huawei that had been undertaken by SolarEdge in Germany last summer. While Huawei has decided not to comment on the matter, the Chinese manufacturer revealed that it had filed three patent litigation claims against SolarEdge at a Chinese court this May.
New aluminum batteries for renewables storage
The devices, developed by a European research team, are said to have twice the energy density of conventional aluminum devices. The scientists used a cathode made of anthraquinone, instead of one based on graphene, increasing energy density.
Solar-plus-storage to provide all the daytime electric needs of nation state
A 6 MW solar plant and 5 MW/2.5 MWh storage system are set to increase the share of renewable electricity on the Pacific island of Nauru from 3% to 47%. The $27 million project is being supported by the Asian Development Bank (ADB).
Logic supports renewables, not nuclear
The latest edition of the World Nuclear Industry Status Report reiterates that clean power is taking the lead in the world’s energy system and nuclear is not only too costly a remedy for carbon emissions but too slow to deploy.
Vietnam may cut FITs for large scale solar 20%
The tariff for rooftop PV will be maintained at $0.0935/kWh but payments for ground-mounted and floating solar could be cut to $0.0709/kWh and $0.0769, respectively. The previous FIT scheme, according to government figures, has driven the deployment of around 5 GW of solar generation capacity.
Live fast, die young: MIT study proposes use of 10-year panels
Research has found even short-lived, 10 to 15-year solar panels could provide enough return for bankable projects. The researchers believe panel costs, coupled with an industry mindset now fixed on the final solar energy price rather than costs per kilowatt installed, may open opportunities for PV products currently snubbed because of a short lifecycle.
The blackest black for more efficient solar cells
MIT scientists claim to have created a material 10 times more black than anything witnessed to date. It is said to be able to absorb more than 99.96% of incoming light and reflect 10 times less light than other superblack materials. The invention may be interesting for the development of black silicon PV technology and carbon nanotube-based solar cells.
The Chinese solar market is changing shape
Two reports have described how the world’s largest renewable energy market is moving towards maturity. According to the Brookings Institution, the Chinese clean energy market could become more open to Western investors and tech. A report by Fitch claims projects are moving back to inland provinces from coastal regions.
A new spectroscopic method to understand the physical principles of organic PV
A German research team claims to have created a new visualization technique it says can enable detailed mapping of the energetic landscapes of organic PV cells on a nano scale. The technique could lead to organic cells with reduced power losses.
