RenewSys has announced the production of six bus bar (6BB) solar PV cells and modules. The 6BB cells, part of RenewSys’ RESERV range of solar PV cells, will be manufactured using world-class European PV cell equipment. The new 6BB cells are said to deliver higher module power and improve performance vis-a-vis standard 5BB cells and modules. By increasing the number of bus bars in a PV cell along with improved design, the company aims to lower the series resistance and resistive loss, thereby improving cell efficiency. The refined design of these cells reportedly optimises the collection of current and reduces losses due to cell shadowing. The company claims lower power degradation in cells due to a reduction in the distance travelled by charge carriers under thermal cycling. The new 6BB cells also promise lower susceptibility to power degradation due to micro-cracks, improvement in reliability and long-term stability. This improved design can thus increase the module power output.
