Dr Helen Zhou, Module Technical Director – JA Solar | Topic: Comparative Study of Field Performance from Modules with Different Designs

In the past few years, passivated emitter and rear cell (PERC) has become the prevailing technology to achieve high energy conversion efficiency for Si-wafer based solar cells in the PV industry, and JA began the PERC mass production from 2014. A lot of modules designs are developed based on the PERC structure. Different cell and module designs result in different module parameters as well as the different outdoor performance.

In this presentation, we will discuss the field performance of modules based on different designs, and factors influencing the module field performance will be discussed. Based on these studies, JA choose product designs with high reliability and superior performance, providing cost-effective products to customers.
