Up-conversion Nanoparticle Perovskite Photovoltaic Device under Indoor LED and Outdoor Local Spectral Irradiances

The increase in global energy consumption has stimulated interest in exploring more clean and sustainable energy sources. Perovskite photovoltaic (PPV) modules have gained great attention as a complementary technology due to their high performance and myriad applications including flexible PV. Furthermore, PPV devices offer new prospects of PV such as scalability, low production costs, and compatibility with numerous coating and printing techniques. This study aims to assess the performance of up-conversion nanoparticle (UCNP) PPV devices under indoor LED lighting and outdoor local irradiance conditions. A theoretical model was developed to compute the power conversion efficiency (PCE) of UCNP PPV devices using measured spectral irradiances and device electrical properties. The results demonstrated that the PCE of UCNP PPV devices under outdoor local irradiance was 19.25%, which was larger than under AM1.5G of 18.7%. However, the PCE under indoor LED lighting was lower, at 14.23%. The results demonstrate the need for strategies to improve the performance of the UCNP PPV device under LED lighting conditions.
