Woodburn Capital, Magna Exteriors sign 15-year solar PPA in Czechia
Magna Exteriors and Woodburn Capital Partners have signed a 15-year solar power purchase agreement (PPA) in Czechia. The agreement covers energy generated on-site at a 2.4 MW solar plant located at Magna Exteriors’ site in the northwestern part of the country.
Chinese PV Industry Brief: Beijing probes EU investment barriers for PV
The Chinese government is launching an investigation to determine whether the European Union is blocking Chinese solar investments.
VIPV in refrigerated trucks can ‘easily’ offset energy demand it creates and meet chiller demand
Germany’s Fraunhofer ISE investigated thermal effects and net energy gains of a 3.2 kW vehicle integrated PV (VIPV) system installed on a freight truck with a refrigerated cargo storage area. It found that with battery storage the system could potentially meet the entire energetic needs of the cooling unit throughout the year in some cases.
U.S. researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation
A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
Chinese PV Industry Brief: JA Solar expects $110 million net loss for H1
JA Solar says it has incurred a $110 million net loss for the first half of 2024, due to rising competition in the solar market, continual price declines, lower gross profit from core operations, and significant provisions for inventory depreciation.
Using digital twin, roll-to-roll platform to design high-performance organic PV devices
An international team of researchers have demonstrated how to speed up the research and development of scalable, high-performing organic solar cells by using an automated, high-throughput platform. It relies on digital twin technology and roll-to-roll (R2R) printing in a closed-loop system.
