Abstract
The efficiency of solar cell is generally defined at standard test conditions. However, wind direction, wind velocity, tilt angle of panel and solar radiation during operation differ from those at standard test conditions. The effects of operating conditions on the temperature and efficiency of silicon solar cells are widely analysed in literature. In the current work, the thermal performance of perovskite and dye-sensitized solar cells in operating conditions has been analysed and compared with monocrystalline silicon solar cell. The effects of wind direction (wind azimuth angle), wind velocity, tilt angle of panel and solar radiation on the temperature and efficiency of the cells have been analysed. The results show that as wind azimuth angle increases from 0° to 90°, the temperature of the cell increases from 51.8°C to 58.2°C for monocrystalline silicon, from 45.5°C to 50.7°C for perovskite and from 48.4°C to 53.9°C for dye-sensitized solar cell and the corresponding efficiency of the cell decreases from 22.3% to 21.5% for monocrystalline silicon, from 20.1% to 19.5% for perovskite and from 11.8% to 11.7% for dye-sensitized solar cell.

The temperature and efficiency of monocrystalline silicon, dyesensitized and perovskite solar cells are calculated for various values of wind azimuth angle, wind velocity, tilt angle of panel and solar radiation
The results show that as the wind azimuth angle increases from 0° to 90°, the temperature of the cell increases from 51.8 °C to 58.2 °C for monocrystalline silicon solar cell, from 48.4 °C to 53.9 °C for dye-sensitized solar cell and from 45.5 °C to 50.7 °C for perovskite solar cell and the corresponding efficiency of the cell decreases from 22.3% to 21.5% for monocrystalline silicon, from 11.8% to 11.7% for dye-sensitized solar cell and from 20.1% to 19.5% for perovskite solar cell
Summary
Solar photovoltaic is one of the fastest growing renewable technologies. In solar cells, only a fraction of the incident solar radiation gets converted into electricity. Rest of the solar radiation gets converted into heat and raises the temperature of the cell. The temperature rise affects the efficiency (solar radiation to electricity conversion) of the cell. The efficiency of solar cells is generally defined at standard test conditions. Ambient and operating conditions differ from those of standard test conditions
