Sunrise brief: Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Also on the rise: Flyover footage of a 6.5 MW community solar project in Maine. The PV Magazine states of solar tour stops in North Carolina. And more.
Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Researchers at the National Renewable Energy Laboratory made a breakthrough in high efficiency and stability for perovskite solar cells.
DOE funds $11 million battery research center at University of Michigan
The new research center will focus on the development of advanced batteries and fuel cells for electric vehicles.
Aluminum-sulfur battery for small-scale storage at $8.99/kWh
Massachusetts Institute of Technology researchers have developed a battery with two electrodes made of aluminum and sulfur, and a molten salt electrolyte placed between them. They said the sulfur electrodes with a high loading of 12.0 mg cm2 can sustain a high capacity of 520 mAh g–1 over 100 cycles at 5 C.
Lab manufactured perovskite solar panel goes nine months, loses 25% of its efficiency
Researchers built and deployed a nine perovskite solar panel array that showed little generation loss due to high temperatures, and performed better over time than researchers expected.
Solar on canals moves closer to reality
Project Nexus expects to break ground in fall 2022 and reach completion by the end of 2023.
Toyota and NREL partner to develop MW-scale fuel cell systems
The two will study the scaling and integration of fuel cell systems for stationary power generation.
New platform centralizes PPA market data
LevelTen Energy, a renewables transaction infrastructure company, has launched a new platform to simplify and accelerate power purchase agreement market analysis. The new platform, MarketPulse, provides 24/7 access to PPA price data, renewable energy project data, and analytics.
Designing for 100% renewables with real-time retail pricing could yield benefits of 9% or more
Including real-time pricing of retail electricity in the design of a high-renewables system would “markedly” lower the system’s cost, researchers found, in an analysis for the island of Oahu, Hawaii. For continent-scale systems as well, they said the resulting demand-side flexibility is likely substantial.
High-performance aqueous calcium-ion battery
Researchers from Rensselaer Polytechnic Institute in the United States have developed a special class of materials for bulky calcium ions, providing pathways for their facile insertion into battery electrodes.
