EU set to dig into raw materials supply
The European Union has drawn up new regulations to boost the domestic mining of raw materials and support production of renewable energy products and materials at home. Will it be enough to incentivize investment, or will Europe trail other major economies, such as the United States and China?
Two solar leaders plan 5 GW solar module factory in U.S.
The two companies have partnered on a new venture that will bring 5 GW of solar cells and 5 GW of solar modules to U.S. and EU markets.
Long-duration stability of perovskite solar cells
US scientists have analyzed the impact of “seasoning” a formamidinium lead iodide solution with two-dimensional (2D) perovskites. They have found that the template improved the efficiency and durability of their solar cells.
Longi claims 34.6% efficiency for perovskite-silicon tandem solar cell
The European Solar Test Installation (ESTI) has confirmed Longi’s achievement of a world record-breaking efficiency rating of 34.6% for a perovskite-silicon tandem solar cell.
Study estimates global floating solar potential at 1,302 TWh
A UK-based research team has calculated the global potential of deploying floating solar arrays on almost 68,000 lakes and reservoirs. It found some countries could generate the majority of their electricity needs from floating solar panels, while five could meet all their electricity demand.
MPPT-based photovoltaic micro-power system with tracking accuracy of 99.25%
Conceived for use in wearable electronics, the micro-power system utilizes a MPPT structure based on a customized FOCV algorithm, a DC-DC converter, a load or a rechargeable battery, a flowchart of MPPT, and a microcontroller.
Semitransparent organic cell achieves bifaciality factor of 99.1%
A team of researchers from two Chinese universities achieved a bifaciality factor of 99.1% with a semitransparent organic cell, the highest reported bifacial factor in such cells to date. The cell also achieved a power conversion efficiency of 12.5% and an average visible light transmittance of 22.9%.
Maxeon reveals minimized risk of hotspots in IBC solar panels
Maxeon’s Interdigitated Back Contact (IBC) solar panels were found to disperse heat evenly, leading to lower operating temperatures in the shade and reduced degradation.
U.S. startup plans perovskite solar factory
Swift Solar, a specialist in perovskite tandem photovoltaics, plans to build a factory in the U.S. in the next two to three years to manufacture thin-film solar.
Zirconium-doped indium oxide electrodes for heterojunction solar cells
A research team including scientists from Italian module manufacturer 3Sun has tested new zirconium-doped indium oxide electrodes in commercial heterojunction solar modules. The new electrodes reportedly achieve the same performance as their counterparts based on indium tin oxide and paves the way for lower indium consumption in heterojunction products.
