Agrivoltaics may increase forage quality in semi-arid regions

New research from the United States showed agrivoltaic plants on grassland may not only maintain grass productivity but also increase forage quality. The scientists took their measurements at the Jack’s Solar Garden (JSG), an elevated, south-oriented agrivoltaic research facility using single-axis-tracking systems near Longmont, Colorado.

Sharp unveils 575 W TOPCon solar panel with 22.26% efficiency

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%.

Polysilicon prices could hit all-time low by year-end

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.

Renewables helping China to halve power prices compared to US, Europe

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 debuts heat pump turbine for homes, businesses

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.

Solar module prices may reach $0.10/W by end 2024

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.

Inverted perovskite solar cell achieves 25.1% efficiency via new passivation technique

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.

Gallium arsenide solar cell achieves 23.1% efficiency via electrochemical porosification

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.

Mysterious, higher energy yields in vertical PV systems

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.


NREL presents new GaAs solar cell concept with 27% efficiency

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.
