Abstract Despite the significant advancement of the data-driven studies for physical science, the textual data that are numerous in the literature are not fully embraced by the physics and materials community. In this manuscript, we successfully employ the natural language processing (NLP) technique to unsupervisedly predict the existence of solar cell types including the dye-sensitized solar cells and the perovskite solar cells based on literatures published prior to their first discovery without human annotation. Enlightened by this, we further identify possible solar cell material candidates via NLP starting with a comprehensive training database of 3.2 million paper abstracts published before 2021. The NLP model effectively predicts the existing solar cell materials, while an uncommon solar cell material namely PtSe2 is suggested as an appropriate candidate for the future solar cells. Its optoelectronic properties are comprehensive investigated via first-principles calculations to reveal the decent stability and optoelectronic performance of the NLP-predicted candidate. This study demonstrates the viability of the textual data for the data-driven materials prediction and highlights the NLP method as a powerful tool to reliably predict the solar cell materials.

AbstractThe Photovoltaic Engineering Testbed (PET) is a facility to fly on the International Space Station to test advanced solar cell types in the space environment. The purpose is to reduce the cost of validating new technologies and bringing them to spaceflight readiness by measuring them in the in-space environment. The facility is scheduled to be launched in 2002.

Solar Cell Performance

In comparisons of solar photovoltaic performance, variation in the spectrum of sunlight is infrequently considered. A single spectrum, AM1.5, is used as the standard condition both for comparison of competing solar cell technologies and evaluation of energy generation from solar power plants. The addition of solar spectrum variation provides a more relevant basis for comparison and reduces prediction error and its financial impacts. Ground-level measurements collected worldwide have been pooled to provide an extensive – though by no means comprehensive – sampling of the global variation in spectral irradiance. Applied to nine solar cell types, the resulting variation in solar cell performance indicates that a single spectrum is not sufficient for comparison of cells with different spectral responses. The performance of different cell types diverges from that under standard conditions. Increases in the degree of sun tracking decrease efficiency for cells with a narrow spectral response. Cells with two or more junctions tend to have efficiencies below that obtained under AM1.5. Of the nine cell types, silicon exhibits the least spectral sensitivity: the median relative variation at a single site is 3%.

Considerations are held about the specificationin whichthe PV plants have to fulfill so that they can be installed on marine vessels. Initially, a brief description of the typical electrical grid of ships is presented, distinguishing the main parts, reporting the typical electrical magnitudes, and choosing the most preferable installation areas. The technical specifications,in whichthe PV plants have to be compatible with, are fully described. They are determined by the special marine environmental conditions, taking into consideration parameters like wind, humidity, shading, corrosion, and limited installation area. The work is carried out with the presentation of the most popular trends in the field of solar cell types and PV system technologies and their ability to keep up with the aforementioned specifications.

Cell Parameters

A limitation in the performance rating of solar cells and modules is that they are tested using a single value for the solar spectrum. To map the performance expected under the varying spectra found in operating conditions, solar cell efficiencies have been evaluated using solar spectra generated by the National Solar Radiation Database, applied to confirmed record-efficiency cell parameters. Nine solar cell types (single-junction and multijunction) are evaluated using spectra at more than forty locations, spanning 76° of latitude and 150° of longitude, at hourly intervals over a year. Relative to the standard test efficiency, increases in annual operating efficiency are seen in cadmium telluride and (single-junction) perovskite designs, while efficiency decreases are observed in two-terminal multijunction structures. Though silicon exhibits the least variation, its -3% to +2% range is equivalent to 20° C of temperature variation. This divergence in operating efficiencies indicates that evaluation using a single spectrum is not a sufficient basis for comparison, or prediction of energy yield in operation. Application of additional “operating spectra,” to supplement the standard test spectrum, is proposed.
