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 polysilicon capacity could hit 2.75 million metric tons (MT) by the end of December, with just 200,000 MT of the total outside of China.

Japan’s latest procurement exercise was open to PV projects above 250 kW in size. The lowest price came in at JPY 7.94 ($0.053)/kWh, with 105 MW of allocated capacity.

Scientists in Korea have proposed a simple methodolgy to tranform existing PV systems into photovoltaic-thermal (PVT) arrays. They claim the new design offers a cheaper alternative to expensive PVT systems, while enabling easier and faster deployment.

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.

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.

Achieved by scientists led by the National University of Singapore, the result is the highest efficiency ever recorded for a perovskite-CIS tandem solar cell at the research level to date. The researchers used methyldiammonium diiodide (MDADI) to reduce open-circuit voltage losses in the top perovskite cell.

A Spanish-Algerian reserch group has tested how “cool roofs” could help increase power yield in rootop bifacial PV systems. Cool roofs are based on coating materials with high reflectance properties.

Researchers in China have built a prototype of a spectral-splitting concentrator agrivoltaic system (SCAPV) with a PV efficiency of 9.9, a hybrid light-use efficiency rating of 9.05%, and a levelized cost of energy (LCOE) of $0.033/kWh.

Researchers in the Netherlands have proposed the use of residential PV capacity to supply electricity to urban loads such as tram substations and dwellings, potentially reducing PV curtailment and demand for additional storage.

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.
