UK researchers warn of potentially rising silver costs
A study has highlighted that the two growth phases of solar panel manufacturing – after the 2008 global downturn and again after 2011 – coincided with higher prices for the precious metal.
Australian researchers to develop new tandem PV cell measurement equipment
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Adelaide-based laser supplier Lastek are developing equipment and procedures to accurately measure the performance of multi-junction solar cells with the help of an LED-based solar simulator.
EkoRE breaks ground on 1 GW vertically integrated module factory in Turkey
The facility is in the Bor organized industrial zone of Niğde, in central Anatolia. The factory was backed by incentives provided by the country’s Ministry of Energy and Natural Resources.
Longi rejects Hanwha Q Cells allegations and provides details on patent issue
The Chinese monocrystalline module maker said it had not been notified of the legal action by its Korean rival. Longi claimed there is considerable uncertainty over the validity of the patents at the root of the lawsuits, which the Chinese defendant says relate to ALD technology. Longi says it uses PECVD technology for cell production.
Hanwha Q-Cells sues Jinko, Longi and REC for patent infringement
The Korean solar manufacturer has lodged a patent infringement lawsuit against Jinko and REC in Germany, and two more against the same companies plus Longi in the U.S. Hanwha Q Cells claims its three rivals have used its patented solar cell passivation technology to increase the performance of their products.
Understanding why cesium and rubidium salt improve the yield of perovskite solar cells
The addition of either salt enables more even distribution of halide atoms within the perovskite material – key to increasing cell conversion efficiency. The explanation should speed up the process of identifying the best perovskite mixes.
Silver price to rise 7% this year
According to the Silver Institute, demand for the precious metal in the solar industry will remain stable up to 2022, despite recent changes in China’s PV policy.
Singlet fission may raise theoretical efficiency of solar cells to 44%
According to a U.S. research team, new nanomaterials relying on dyes based on diketopyrrolopyrrole and rylene can generate a singlet fission reaction that extends the life of harvestable electronic charges.
German researchers increase open circuit voltage of perovskite solar cells to 1.26 volts
The voltage is key to improving efficiency, the scientists say. It indicates how much energy is lost within the cell through ‘recombination processes’.
Jinko achieves 24.2% efficiency for its n-type monocrystalline cell
The Chinese module maker said the result was certified by the Photovoltaic and Wind Power Systems Quality Test Center at the Chinese Academy of Sciences. The record, Jinko said, is thanks to its high quality n-type wafers, selective doping technology and advanced fine-line printing.
