Modules & Upstream Manufacturing

US-based Maxar Technologies used satellite imagery imagery with resolution of 31 cm to 15.5 cm to identify rooftop PV systems in southern Germany. The company claims its new approach was able to identify 97.8% of the solar arrays with high confidence.

The scientists built the device by depositing multiple metal nanofilms on both sides using plasma-enhanced chemical vapor deposition. The cell achieved an open-circuit voltage of 684 mV, a short-circuit current density of 38.2 mA/cm2 and a fill factor of 80.8%.

A research team in Spain has developed a PV system layout for super-intensive olive groves. The scientists said the system must ensure high levels of transparency in order to avoid a negative impact on the olive yield.

South Korean researchers have developed a long-term solar irradiance prediction method based on a reinforcement learning algorithm. They claim that the new model is able to forecast solar radiation for more than a year using just two weeks of solar radiation learning.

Toledo Solar and First Solar have reached an agreement in their lawsuit, but details of the settlement remain confidential. Toledo Solar has also revealed the formation of a new investor-led independent board of directors and leadership team.

A French-Spanish research team developed organic photovoltaic modules embedded into plastic parts through high throughput injection molding. The researchers injected thermoplastic polyurethane in the modules and found it enhances their mechanical stability while keeping a high flexibility.

Encouraged by lab results and a feasibility study, Swedish startup, Green14, in collaboration with Sweden’s Royal Institute of Technology (KTH) plans to build a pilot-scale reactor to make solar grade silicon with a hydrogen plasma process. The company sees the pilot as a step towards using a more sustainable method to produce solar grade silicon for the PV industry at its own gigawatt-scale plant.

SolarPower Europe’s board members have issued a joint statement calling for three measures to safeguard the European solar industry, as they claim that tariffs and trade barriers are not viable solutions.

Massachusetts Institute of Technology (MIT) researchers have developed a solar desalinator with high water output, via a multi-stage system of evaporators and condensers. It offers cost-effective solar desalination, making solar-produced drinking water cheaper than tap water for the first time.

A research team in Bangladesh has simulated a perovskite-CIGS PV device that can reportedly achieve a remarkable tandem cell voltage of 2.48 V. The proposed method is also applicable for tandem cells composed of other materials.
