Aleo Solar unveils 345 W rooftop photovoltaic module
The new panel from the German manufacturer may also be used as a solar tile and is claimed to be particularly suitable for historical buildings and aesthetically demanding new construction and renovation projects.
Integrated solar roof from India
Visaka Industries’ patented Atum solar roof is reportedly able to reduce building temperatures by up to 40%.
Using p-type wafers in heterojunction solar cells, not a lost battle
An international research group has reconstructed the trajectory of p-type wafers in the heterojunction solar cell segment and has identified the lack of knowledge about boron-oxygen related light-induced degradation (BO-LID) as the main cause for the limited adoption of these wafers and the success of their n-type counterparts. According to the scientists, however, there is still big room for improvement for p-type technologies in heterojunction cells.
Photovoltaic micro-inverter based on gallium nitride transistors
Scientists from France’s CEA-Ines developed a 400 W micro-inverter with a power density of 1.1 kW/L and an efficiency of 97%. The device utilizes GaN 600V diodes and power transistors developed by CEA’s electronic branch CEA-Leti.
South Korea’s largest renewables PPA
SK Specialty has agreed to buy electricity from 50 MW of renewable energy assets located in South Korea’s South Chungcheong Province from 2024 to 2044 at an undisclosed price.
US 2021 solar panel shipments total $9.8 billion at $0.34/W
Solar module prices fell despite supply chain pressures, rising shipping costs, and increased materials costs.
US solar sector prepares to meet smart inverter requirements
As several US states will soon require smart inverters for new distributed resources, and more are considering such a requirement, nearly all manufacturers will be delivering smart inverters that meet a new industry standard by August 2023, finds an analysis by the Interstate Renewable Energy Council.
India’s solar report card for FY 2021-22
India installed 12.3 GW of solar in the 12 months ending March 31, 2022. The nation is expected to add a record 20 GW in the current fiscal year.
Surface engineering for an 18.6% efficient large-area inverted perovskite solar cell
Scientists in China worked with nickel-oxide as a charge transport layer in a perovskite solar cell, and were able to overcome several of the performance challenges associated with this material through careful surface engineering. Using this approach, the group fabricated an inverted perovskite solar cell measuring 156×156 mm that achieved 18.6% efficiency, along with ‘remarkable’ stability, according to its designers.
Germany deployed 3.8 GW of PV in first half of 2022
In June alone, new PV systems totaling 612 MW were connected to the German grid. The country’s cumulative operational PV capacity reached 59.9 GW at the end of June.
