Graphical Abstract Perovskite solar cellsexhibit improved photovoltaic parameters with increasing perovskite grain size. The larger photocurrent is due to the enhanced absorption efficiency for thicker perovskite layers. The larger open-circuit voltage (VOC) is ascribed to the reduced trap-assisted recombination for the larger grains.
Sahu et al. constructed a small molecule dataset of 280 organic photovoltaics and used 13 microscopic descriptors to build a model to predict the PCE of organic photovoltaic cells with a model Pearson coefficient of 0.79, which can be applied to high-throughput screening of new organic photovoltaic materials.
However, there is an upper limit to the light-to-electrical power conversion efficiency (PCE, which is the ratio between the incident solar photon energy and the electrical energy output) of single-junction solar cells that is determined by the Shockley–Queisser (SQ) model and formalism 1.
The results suggest that the cell performance was very efficient for the moderate illumination intensity of about 1 sun, and the cell performed at best PCE values for low series and high shunt resistance. Finally, this novel configuration is suited well when compared to other similar configurations experimentally as well as theoretically.
At present, a cell with an area of 79 cm 2 has already demonstrated a PCE of 26.7%, and a cell with an area of 180 cm 2 (which would be a truly amazing size for other PV technologies) reached a PCE of 26.6%. These cell results lead us to anticipate that the module efficiency will also increase in the near future.
