DEWA unveils new method to measure current-voltage curves in PV systems
A group of scientists from the UAE-based energy utility has developed a new method to conduct I-V curve measurements without transporting the solar modules to laboratories for detailed analysis. The proposed Suns-Vmp approach reportedly offers a “very low” average root mean square error between the simulated and the real I-V curves.
Researchers discover method to help perovskite solar cells self-heal
A global team of researchers – lead by Monash University in Melbourne, Australia – says it has made a breakthrough that could make perovskite solar cells more reliable and efficient.
Pontoon-type structure for offshore floating photovoltaics
Researchers in China have developed a floating structure for offshore PV that reportedly offers improved stability and dynamic responses compared to conventional semi-submerged floating designs. The floating structure consists of pontoon-truss platform composed of four pontoons and a steel truss connected by soft ropes.
The many potentials of solar energy
In addition to producing renewable electricity, solar energy can also enable the clean production of hydrogen. Its potential in different applications is being assessed by several teams of researchers around the world. Adrian Pennington reports on some of this R and D and how IEC Standards can help in the third of the IEC columns for pv magazine
