Scientists at the Energy Department’s National Renewable Energy Laboratory (NREL) have demonstrated a way to significantly increase the efficiency of perovskite solar cells by reducing the amount of energy lost to heat.
A paper on the discovery, “Observation of a hot-phonon bottleneck in lead-iodide perovskites,” was published online this week in the journal Nature Photonics. The research also will appear in the January print edition of the journal.
Present-day photovoltaic cells can only effectively utilize about a third of the available energy, with another third lost to heat and the rest lost to other processes instead of being converted …read more
