Effective defects

Defects are normally detrimental to the power conversion efficiency of solar cells. Du et al. show that in quantum-dot-sensitized solar cells charge-trapping defects assist photoconversion and increase efficiency by supporting charge transfer to the electrodes.

  • Editorial | 20 May 2020

    Policy should pay closer attention to the increasing body of research on the links between energy, climate and health.

    The COVID-19 pandemic and associated changes in social and economic conditions may affect the prevalence of energy insecurity. Essential relief must be provided to the growing number of households that are energy insecure and protect them from even more dire circumstances caused by utility disconnections and unpaid energy bills.

    Low-cost, efficient hydrogen production via water electrolysis is expected to be an important part of a future hydrogen economy. Towards this end, new polymers with high stability are demonstrated and paired with low-cost, earth-abundant metal catalysts in alkaline membrane electrolyzers.

    Microsized battery anodes such as silicon offer cost advantages over nanosized counterparts but suffer from poor cycling stability. Now, an electrolyte design is reported to enable a LiF-rich solid–electrolyte interphase that stabilizes microsized silicon over a reasonably long cycle life.

    The power conversion efficiency of solar cells sensitized with colloidal quantum dots is believed to be limited by surface defects. Research now finds that photocarriers trapped at shallow defect states can actually be recovered and ultimately contribute to device efficiency.

Policy Brief

  • Policy Brief | 01 May 2020

    Retiring, transitioning or installing more stringent emissions controls in coal-fired power plants has the potential to decrease asthma attacks and asthma-related emergency department visits and hospitalizations in nearby communities. These health co-benefits should be considered in policy and decision making about coal-fired power plant retirement or retrofit.

    Production of hydrogen fuel by electrolysis of low-grade or saline water, as opposed to pure water, could have benefits in terms of resource availability and cost. This Review examines the challenges of this approach and how they can be addressed through catalyst and electrolyser design.
