When we visit conferences and industrial players, we are very often surprised at how many responsible scientists for PERC production have never heard about the severe degradation effects that PERC devices can show – in particular when talking about LeTID (Light and elevated Temperature Induced Degradation) alias Carrier Induced Degradation (CID).
SPONSORED: Falling system prices have been a key driver of PV's recent growth and competitiveness, but upfront costs are only one part of the equation for long-term profitability within the solar power industry. Maximising any given system’s cumulative power output over its lifetime is critical to lowering the levelised cost of electricity (LCOE) and maximising investment returns.
The PERC (Passivated Emitter Rear Cell) cell and module technology have been widely adopted by the industry. JA Solar has been exploring innovative approaches of bifacial PERC cell and the methods of making it and has been granted two Chinese patents. Also, a series of experiments have been carried out to certify the higher efficiency of bifacial PERC modules than conventional PERC modules.
