A small guest molecule in the right place makes it possible to produce energy-efficient organic solar cells using eco-friendly solvents. A record efficiency over 17% is demonstrated. In addition, solar cells with larger areas can be produced.
Rice University engineers have achieved a new benchmark in the design of atomically thin solar cells made of semiconducting perovskites, boosting their efficiency while retaining their ability to stand up to the environment.
Today's solar modules are mainly made of silicon, and possibilities for further increases in efficiency have already been largely exploited.
Researchers from the University of Cambridge have used a suite of correlative, multimodal microscopy methods to visualise, for the first time, why perovskite materials are seemingly so tolerant of defects in their structure. Their findings were published today in Nature Nanotechnology.
A research group at the Norwegian University of Science and Technology (NTNU) has developed a method for making an ultra-high material efficient solar cell using semiconductor nanowires.
Organic solar cells, which can be applied to flexible wearable electronic devices, indoor light-harvesting applications, building-integrated photovoltaics, and the internet of things, have attracted particular attention.
The development of new-type thin-film solar cell technology is groundbreaking, it opens up the possibility of introducing clean energy into modern families most cordially, and will bring a new way of life.
Bulk photovoltaic effect is widely used in generating electricity. As a process of energy transference from photons to electrons and of voltage formation within ferroelectric material, BPVE acts like a dam, raising up "water" to generate "power".
An exciting new solar material called organic-inorganic halide perovskites could one day help the U.S. achieve its solar ambitions and decarbonize the power grid.
Researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be overcome.
