The hidden cause of module degradation and how to avoid it in your future deployments

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.

Black Silicon: There’s more than meets the eye

Inline quality rating of multicrystalline wafers

With the transition of the cell structure from aluminium back-surface field (Al-BSF) to passivated emitter and rear cell (PERC), the efficiency of multicrystalline silicon solar cells becomes more and more sensitive to variations in electrical material quality. Moreover, the variety of multicrystalline materials has increased with the introduction of high-performance multicrystalline silicon. For these reasons, a reliable and verifiable assessment of the electrical material quality of multicrystalline wafers gains importance: to this end, a rating procedure based on photoluminescence imaging has been developed.
