Imagine a car whose windows and sunroof can help top up its battery while parked under the sun, or a pair of smart glasses whose lenses can harvest light to power built-in electronics.

Such applications could become more feasible with a new type of ultrathin transparent solar cell developed by scientists from Nanyang Technological University, Singapore (NTU Singapore).

Led by Associate Professor Annalisa Bruno, the NTU researchers created perovskite solar cells that are about 10,000 times thinner than a strand of human hair and around 50 times thinner than conventional perovskite solar cells.

Despite their thinness, the devices ...

In an article published in the Journal of Materials Chemistry C, Brazilian researchers describe a strategy to enhance the efficiency and stability of solar cells made of perovskite, a semiconductor material produced in the laboratory. The results of the project could be highly positive for the future of the solar power sector.

Developed by researchers at São Paulo State University (UNESP) in Bauru, Brazil, the method involves the use of a class of materials known as MXenes, a family of two-dimensional materials with a graphene-like structure combining transition metals, carbon and/or nitrogen, and surface functional groups such as fluoride, oxygen or hydroxyl...

Northwestern University researchers have raised the standards again for perovskite solar cells with a new development that helped the emerging technology hit new records for efficiency.

The findings, published today (Nov. 17) in the journal Science, describe a dual-molecule solution to overcoming losses in efficiency as sunlight is converted to energy...

Solar technologies have become increasingly advanced over the years, with the discovery of new photovoltaic materials and designs. While solar cells based on a mixture of organic and inorganic halide perovskite materials have been the topic of numerous research studies and achieved promising performances, these cells are often difficult to fabricate on a large-scale.

Researchers at Chonnam University in South Korea recently introduced an alternative solar cell design fully based on inorganic perovskites. Their solar cells, introduced in Nature Energy, could be easier to fabricate on a large-scale, while nonetheless achieving promising power conversion efficiencies (PCEs).
