For decades, scientists have been stumped by the signals plants send themselves to initiate photosynthesis, the process of turning sunlight into sugars. UC Riverside researchers have now decoded those previously opaque signals. For half a century botanists have known that the command center of a plant cell, the nucleus, sends instructions to […]
This study is led by Prof. Kun Yang (Department of Earth System Science, Tsinghua University). Surface solar radiation (Rs) data is the essential information for the development of solar power usage to mitigate the ongoing climate change. To meet China’s carbon neutrality goal, China has invested and planned heavily in the solar photovoltaic systems. […]
Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this […]
Lead halide perovskite nanocrystals (PeNCs) have attracted extensive attention due to their high photoluminescence quantum yield (PLQY), adjustable bandgap, low cost, and excellent photoelectric properties. In recent years, perovskite based light emitting diodes (LEDs) have developed rapidly and become candidates for low-cost, solution-processing based solid-state lighting. White light perovskite LEDs are possible […]
A new pathway to creating durable, efficient perovskite photovoltaics at industrial scale has been demonstrated through the first effective use of lead acetate as a precursor in making formamidinium-caesium perovskite solar cells. Members of Exciton Science, based at Monash University, were able to create perovskite solar cells with 21% efficiency, the best […]
The past two decades have seen drastic progress in the development of semiconducting metal-halide perovskites (MHPs). The excellent optoelectronic properties and device performance make perovskites very attractive in various fields. Photo-processing has been demonstrated to be a facile and general technique for synthesizing perovskites, modifying their structures, and create patterns and devices. This review […]
