PV industry benchmarks for module technology and bankability are driven by JinkoSolar

The PV industry roadmap - and related metrics of technology and bankability - are now being driven by leading module supplier, JinkoSolar, with others seeking to replicate Jinko’s product line options, trying to differentiate in markets that are receptive to low-cost alternatives, or focusing only on rooftop markets where volumes are lower and sales/distribution efforts are more intensive.

Why are monocrystalline wafers increasing in size?

The PV industry is undergoing rapid technology changes that have been driven by the well documented, swift adoption of monocrystalline wafers. Less well understood is that, within this wafer technology transition comes a shift to larger wafer sizes and this includes p-type and n-type mono-Si wafers.

LONGi investing US$875 million in 2020 production capacity expansion plans

Leading monocrystalline wafer producer and ‘Solar Module Super League’ (SMSL) member LONGi Green Energy Technology is planning to invest around US$875.7 million in expanding its Czochralski-based monocrystalline silicon (mono-Si) ingot and wafer capacity by 15GW, while expanding mono-Si solar cell capacity by an initial 3GW in 2020.

LONGi to build new 1GW mono solar cell plant in Malaysia

Leading monocrystalline wafer producer and ‘Solar Module Super League’ (SMSL) member LONGi Green Energy Technology has announced plans to build a new 1GW monocrystalline solar cell manufacturing plant in Kuching, Malaysia.

Beyond boron-oxygen-deactivation: industrial feasible LID-free p-type Czochralski silicon

Today’s industry standard B-doped monocrystalline silicon still suffers from light-induced degradation of the carrier lifetime. Illumination at elevated temperature leads to a so-called regeneration, i.e. a recovery of the carrier lifetime as well as the solar cell efficiency. However, even though the carrier lifetime on test wafers increases from about 1 ms after processing to 3 ms after regeneration, the corresponding PERC+ cell efficiencies in both states are identical. We discuss possible reasons for this discrepancy. Additionally, we evaluate B-doped Czochralski silicon wafers with an ultra-low oxygen content of 2.6 ppma as well as industrial Ga-doped wafers. Both wafer materials are completely LID-free in lifetime measurements and PERC+ cell efficiencies and enable up to 0.4%abs higher efficiencies than present industry-typical boron-doped wafers.
