Japan’s 18th solar auction concludes with lowest bid of $0.053/kWh
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.
Retrofit solution to convert rooftop PV systems into photovoltaic-thermal arrays
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.
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.
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.
Scientists achieve 29.9% efficiency for four-junction perovskite-CSI tandem solar cell
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.
‘Cool roofs’ increase power yield in bifacial rooftop PV systems
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.
Agrivoltaic system achieves 9.9% efficiency, LCOE of $0.033/kWh
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.
Residential PV for urban loads as an antidote to solar curtailment
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.
Researchers shed light on 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.
Sharp claims 33.66% efficiency for silicon tandem solar cell
The Japanese electronic manufacturer said this is the world’s highest efficiency for a stacked solar cell that combines a tandem double-junction solar cell and a silicon solar cell.
