Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.

Bernreuter Research says in a new report that it expects polysilicon prices to soon dip below the historical low of $6.75/kg, which was reached in June 2020. It says global demand could reach 1.1 TW by 2027.

Wood Mackenzie says in a new report that China could install 230 GW of PV and wind capacity and export more than 200 GW of solar panels in 2023. Unlike Europe and United States, the country is avoiding the high curtailment of PV and wind.

Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.

Tim Buckley, director of Climate Energy Finance, speaks to pv magazine about the current steep trajectory of solar module prices. He estimates that PV panels prices will end up dropping by 40% this year and predicts the closure of old technology and sub-scale solar manufacturing facilities, both in China and globally.

A group of scientists in the United States has utilized a new passivation strategy based on sulfur-modified methylthio molecules to build an inverted perovskite solar cell with a certified efficiency of 25.1% and remarkable stability. The proposed passivation approach reportedly led to a five-fold increase in carrier lifetime and a three-fold reduction in photoluminescence quantum yield losses.

An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.

Scientists in the Netherlands have sought to understand the reason for unexpected gains in vertical PV systems and found that these installations have a much higher heat transfer coefficient than their horizontally deployed counterparts.

The US Department of Energy’s National Renewable Energy Laboratory (NREL) has identified a low-cost way to produce high-efficiency III-V solar cells with dynamic hydride vapor phase epitaxy (D-HVPE). The synthesis involved a gallium arsenide (GaAs) solar cell with a gallium indium arsenide phosphide emitter layer.

A new study from Clean Energy Associates (CEA) shows that 83% of sites tested as part of a global survey had line cracks, 78% had a soldering anomaly and 76% had complex cracks. The survey involved visual inspections combined with electroluminescence testing across 148 sites in 16 countries.
