2. Solar-cell efficiency - Wikipedia

   en.wikipedia.org/wiki/Solar-cell_efficiency

   The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system. For example, a solar panel with 20% efficiency and an area of 1 m 2 produces 200 kWh/yr at Standard Test Conditions if exposed to the Standard Test Condition solar irradiance value of 1000 ...

7. Multi-junction solar cell - Wikipedia

   en.wikipedia.org/wiki/Multi-junction_solar_cell

   The theoretical efficiency of MJ solar cells is 86.8% for an infinite number of pn junctions, [14] implying that more junctions increase efficiency. The maximum theoretical efficiency is 37, 50, 56, 72% for 1, 2, 3, 36 additional pn junctions, respectively, with the number of junctions increasing exponentially to achieve equal efficiency ...
