Monolithic perovskite/silicon tandem solar cell with >29% efficiency by enhanced hole extraction Efficiency from hole-selective contacts Perovskite/silicon tandem solar cells must stabilize a perovskite material with a wide bandgap and also maintain efficient charge carrier transport. Al-Ashouri et al. stabilized a perovskite with a 1.68–electron volt bandgap with a self-assembled monolayer that acted as an efficient hole-selective […]

Biden’s First 100 Days: What Would They Look Like for Clean Energy?
Joe Biden has pledged unprecedented action on climate change and clean energy. What might he actually get done? Any candidate running for president has a priority list, both public and internal, laying out what their administration hopes to accomplish in its first days and months. For his part, Democratic presidential candidate Joe Biden has laid […]
Fledgling Solar Technology Promising Output Gains Raises $2.5M
SunDensity, a solar photonics startup, says its technology boosts module output by 20 percent. SunDensity, a solar startup promising 20 percent power output gains* due to specially coated glass, raised $2.5 million in initial financing to begin commercializing its product. If commercially successful, the technology could measurably increase the output of solar panels, reducing the […]
New CIGS/perovskite tandem solar cell reaches 24.16% efficiency and awarded a new branch on the NREL chart
Researchers from Helmhotlz-Zentrum Berlin (HZB), collaborating with teams from University of Cambridge, Eindhoven University of Technology, Nicolaus Copernicus University, Salerno University and others, have developed a monolithic “two-terminal” tandem cell made of CIGS and perovskite that achieved a certified efficiency of 24.16%, with a thickness of well below 5 micrometers – which would allow […]
Tandem PV Secures a Rare Fund Raise for Perovskite Solar
A Silicon Valley startup wants to pair newfangled materials with silicon cells to create a higher-efficiency module. Silicon Valley-based Tandem PV closed a $2.4 million seed round in February to commercialize an exotic new solar technology. The startup is developing perovskite solar materials, which it will layer on top of conventional silicon cells to make […]
Trump Administration Cuts Clean Energy Programs Again in 2020 Budget Request
The proposal zeroes out the DOE loan program and ARPA-E budget. An official said funding will focus on “basic science” and clean energy technologies “that make sense to us.” The Trump administration’s budget for fiscal year 2020 again proposes eliminating programs that fund renewable energy, including the Advanced Research Projects Agency-Energy and the Department of […]
California’s Rooftop Solar Mandate Wins Final Approval
The California Building Standards Commission has signed off on the residential solar mandate — a first of its kind for the nation. It’s official. All new homes in California must incorporate solar power starting in 2020. The California Energy Commission (CEC) passed the measure in May as an update to the state’s 2019 Title 24, […]
