Estimation of cell-to-module power loss from mini-module on selective emitter crystalline silicon solar cells

摘要

In this work, we report a very efficient and low-cost method to estimate the cell-to-module (CTM)power loss of 60-cell module from one-cell module. Moreover, we compare two different kinds of Selective Emitter(SE) solar cell with Homogeneous Emitter (HE) solar cell. According to one baseline experiment of real 60-cell PVmodule, one model is built to qualitatively estimate PV module performance from one-cell level by consideringoptical effect and electrical effect. In this case, we compare two different kinds of SE cells and one HE cell. SE cellswith higher blue response have higher CTM power loss after module due to the higher absorption in the shortwavelength range of encapsulated materials.
