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...

Fraunhofer ISE Reaches New Levels of Efficiency

Fraunhofer ISE claims a new record of a 26 percent absorption rate for a both-sides contacted silicon solar cell. According to Fraunhofer ISE, the system used to set the record has the ability to increase efficiencies by up to 27 percent. Dr. Armin Richter of Fraunhofer ISE led a group of researchers who used Tunnel Oxide Passivating Contact, also known as TOPCon technology, as the foundation for the cell's architecture. The technology had advantages such as low surface recombination failures and effective charge carrier delivery over IBC cells. The cell used to set the efficiency record, on the other hand, had a formed junction on the rear end. This eliminated the need for full-surface boron doping on the front surface, leaving only a small boron diffusion slightly underneath the fr...
