It is well documented that the Earth’s primary means of generating energy involves the burning of fossil fuels, a process which produces pollutant materials like CO 2, resulting in a global-warming effect that could have drastic ramifications on the ecosystem of the planet 1, 2, 3. The databases are available in MongoDB and JSON formats, which can be queried in Python, R, Java and MATLAB for data-driven photovoltaic materials discovery. The DSC database contains 475,045 entries representing 41,680 devices, and the PSC database contains 185,836 entries representing 15,818 devices.

A multi-faceted evaluation, incorporating manual and automatic methods, was applied to ensure that the data contained therein were of the highest quality, with precision metrics ranging from 73.1% to 95.8%.

The databases were generated by applying the text-mining toolkit ChemDataExtractor on a corpus of 25,720 articles. We present two automatically generated databases that contain photovoltaic properties and device material data for dye-sensitized solar cells (DSCs) and perovskite solar cells (PSCs), totalling 660,881 data entries representing 57,678 photovoltaic devices. Consequently, the field could benefit from a central repository where photovoltaic-performance metrics, such as the power-conversion efficiency ( η) are recorded.

8.The number of scientific publications reporting cutting-edge third-generation photovoltaic devices is increasing rapidly, owing to the pressing need to develop renewable-energy technologies that address the climate-change crisis.

Solar Radiation Outside the Earth's Atmosphere.

Thus the input power for a 100 × 100 mm 2 cell is 10 W and for a 156 × 156 mm 2 cell is 24.3 W The input power for efficiency calculations is 1 kW/m 2 or 100 mW/cm 2. The efficiency of a solar cell is determined as the fraction of incident power which is converted to electricity and is defined as: Recent top efficiency solar cell results are given in the page Solar Cell Efficiency Results. Solar cells intended for space use are measured under AM0 conditions. Terrestrial solar cells are measured under AM1.5 conditions and at a temperature of 25☌. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another. In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Efficiency is defined as the ratio of energy output from the solar cell to input energy from the sun. The efficiency is the most commonly used parameter to compare the performance of one solar cell to another.
