The novel technique consists of attaching cotton wicks immersed in the water (CWIWs) to the backside photovoltaic module. The water is supplied to cotton wicks from top to bottom by gravity which the scientists said helps the effective absorption of cotton and reduces water consumption.
New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.
The panel has an absorption area of 1.96 m2 and a weight of 27 kg per square metre. According to the manufacturer – Swiss start-up TVP Solar – it may be a real booster for thermal output, by combining it with photovoltaics and heat pumps to provide enhanced output per square meter, in particular for low-temperature applications such as district heating.
Canadian startup Capsolar claims its flexible solar modules can be adapted to any type of low-speed electric vehicle with no extra modification and custom work. The panels have an efficiency of 21.3% and rely on 24%-efficient solar cells provided by US manufacturer SunPower.
Scientists in Russia have developed a new wide-band optical absorber called ‘black silicide’ which they claim is more adjusted to match AM-1.5 solar spectrum with theoretically higher photogenerated current density. It could be used for tandem operation in photovoltaic devices.
US startup New Use Energy Solutions has launched a new line of portable PV systems built with a module technology relying on Sunpower’s solar cells. The modules are assembled in the system via a custom vinyl tarp.
Chinese manufacturer JA Solar said that tests have shown that n-type modules have a 3.9% higher power yield than their p-type counterparts. Germany-headquartered technical service provider TÜV Nord has confirmed the results.
The fire affected an area of around 5,000 square meters but did not damage the solar panels. The local fire brigade was able to control the fire in around two hours.
A team of researchers from the United Kingdom have found that crack percentages of up to 11% have a very limited impact on solar cell performance. They also ascertained that hotspots are likely to arise when the crack percentage is in the range of 11 to 34%.
An international research team has developed a new methodology to increase levels of pollination at ground-mounted solar plants. It involves the development of new vegetated land cover below and around solar parks.
