Blue is not the new green
A new study from Stanford University and Cornell University shows that blue hydrogen can produce more greenhouse emissions than heat produced by coal and gas. The modeling classifies blue hydrogen emissions as carbon dioxide and unburned fugitive methane, as well as lifecycle emissions linked to the mining, transport, storage, and use of methane.
Recovering waste heat from solar cells using a thermoelectric generator
The device recovers waste heat from the PV unit and produces additional power.
East-west orientation? Here are two new approaches to designing your solar project
Developers say the design approach can prevent soil deterioration and still offer the same yield as south-oriented PV plants.
Got windows? Then photovoltachromics may be for you
Researchers developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature.
Researchers develop a novel design for agrivoltaics
The design uses metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. System costs would be around $847/kW.
NREL develops interoperable SCADA protocols for PV inverters
The codes enable legacy inverters to participate in advanced distribution management.
These organic solar panels generate electricity (and maybe spread a little joy)
A French PV specialist and a Dutch designer who integrates PV into furniture, windows, and other objects, teamed up to provide technology for a pavilion at Expo 2020 in Dubai.
A breakthrough for p-type heterojunction cell performance?
Researchers developed a silicon heterojunction solar cell based on p-type gallium-doped wafers that they said has an efficiency of 22.6% and improved stability.
Solar module cooling techniques for the desert
Researchers tested solar panel cooling technologies and found that active techniques work better than passive ones under harsh climatic conditions.
Holographic light collector could improve solar panel yield
The collector is built with a low-cost holographic optical element and a diffuser and can be easily embedded into conventional PV modules, according to its creators.
