Emerging Solar Cell Technologies Challenge Silicon-Celled Dominance

Strategic Insights -

While silicon-cell photovoltaics have been the primary choice for solar power, new research has emerged that suggests alternative solar cell materials, such as perovskite and chalcogenide, may offer improved efficiency, cost-effectiveness, and sustainability. A recent study compared these emerging technologies with conventional silicon-cell PV, evaluating their energy, economic, and environmental performance in a typical residential building in Detroit, MI.

Key Takeaways:

  • The study found that perovskite solar cells have the potential to outperform silicon-cell PV in terms of energy (energy reduction rate of 30.66% for perovskite and 25.51% for silicon-cell PV in 2050) and economic perspectives (cost savings of $443.71 USD/year for perovskite and $369.26 USD/year for silicon-cell PV in 2050).
  • Perovskite solar cells also exhibit remarkable light absorption capabilities and low-cost manufacturing process, but have high embedded CO2 emissions (1020 gCO2/kWh), resulting in the longest environmental payback period (6.81 years in 2050).
  • Chalcogenide PV was found to be the best from an environmental standpoint, based on performance data.
  • The study aims to help building engineers and PV technicians predict which solar cell materials have the market potential to replace silicon-cell PV and become the 'system of the future' in the solar power industry.
  • The research has been peer-reviewed and published in the journal Applied Energy.
