JinkoSolar beats multicrystalline cell efficiency record

Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar has reported a record solar cell efficiency of 22.04% for a P-type multicrystalline PERC (Passivated Emitter Rear Cell), using its practical sized (245.83cm2) wafer.

In-line quality control in high-efficiency silicon solar cell production

There are numerous tools and methods available on the market for the optical and electrical quality control of high-efficiency silicon solar cells during their industrial production, and even more are discussed in the literature. This paper presents a critical review of the possibilities and limitations of these tools along the value chain, from wafer to cell, in the case of passivated emitter and rear cells, as well as a discussion of some showcases. Economic and technological challenges and future trends are addressed.
