Human Hair to Increase Efficiency of Perovskite Cells

If you had your head shaved at a barbershop near the Queensland University of Technology (QUT) site last year, there's a possibility that you’ve helped in advancing Australia’s cutting-edge solar technology. Human hair clippings from a Brisbane barbershop were used by Australian scientists to build 'shields' that improve the energy conversion capacity of perovskite solar cells. QUT researchers created carbon dots using human hair snippets. Carbon dots are carbon-based materials with dimensions in the tens of nanometers range. These materials will then be used to improve the effectiveness of perovskite solar cells. The was able to create a wave-like nanoparticle coating by surrounding the perovskite particles with carbon dots. The coating functions as a defensive layer, similar to ...

Talesun’s Most Recent Module Series Provides 570/590Wp Output

Talesun Solar has introduced a new line of massive, high-efficiency PERC modules for industrial-scale PV power plants. The series will be released in both mono facial ‘Bistar' and bifacial ‘Bipro' configurations. Each will use 182mm half-cut cells in 144 and 156 cell configurations. They may deliver up to 590Wp output with module efficiencies close to 21.2 percent. Today’s PV market is actively moving toward larger format modules with performance figures reaching 600Wp. This is stimulated by the need to keep decreasing the levelized cost of electricity by reducing the cost of installation and component amount. Having said that, the market now needs three items. The first task is to select and deploy the proper PERC-based module format size. The second step is to innovate at the ce...

First Solar Shipped 5.5GW of CdTe Modules

First Solar announced 5.5GW of PV module deliveries in 2020, producing a net income of $2.7 billion. The SMSL member posted sales of US$609.2 million in the fourth quarter of 2020, down from US$927.6 million the previous quarter. The company has previously stated that it projected net revenue in the fourth quarter to range between US$540 million and US$790 million. The figure accounts for potential delays in the selling of its Sun Streams 2 plan as well as the timing of module sales acknowledgment, which has been postponed until February 2021. Balance sheet cash and cash equivalents were $1.79 billion at the end of last year, down 21% year on year. This owes largely to capital expenditures attributable to the company's transition to Series 6 module manufacturing. First Solar forec...
