The future of solar testing: advancing perovskite and tandem modules

As solar module prices continue to decline, the European industry faces challenges, but emerging technologies like perovskite solar cells offer new opportunities. MBJ Solutions' latest LED solar simulator, the MBJ Sunlike Lab, provides an advanced testing solution for next generation tandem modules, ensuring precise measurements and long-term stability in solar research.

Between 2010 and 2020, prices for solar modules fell by around 80% to 90%. In 2010, the price of solar modules was around USD 3-4 per watt peak, while the price fell to around USD 0.18-0.25 per watt peak in 2020. Current daily prices are sometimes below USD 0.10 per watt peak, often below the manufacturing costs.

In Germany, many factories have ceased production for this reason. Only recently, Aleo Solar announced that its production facility in Prenzlau will be closed after 22 years. The prospects in Europe are no better, although the market for renewable energy continues to grow worldwide.
