How efficient are silicon solar cells for photovoltaic conversion?

Evolution of silicon solar cell efficiency. The theoretical efficiency for photovoltaic conversion is in excess of 86.8% 1. However, the 86.8% figure uses detailed balance calculations and does not describe device implementation. For silicon solar cells, a more realistic efficiency under one sun operation is about 29% 2.

How is solar cell efficiency measured?

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. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.

What is the power conversion efficiency of a solar cell?

AM0 and AM1.5 solar spectrum. Data courtesy of the National Renewable Energy Laboratory, Golden, CO. The key characteristic of a solar cell is its ability to convert light into electricity. This is known as the power conversion efficiency (PCE) and is the ratio of incident light power to output electrical power.

What is the power density of a solar cell?

This has a power density of 100 mW.cm -2 and is equivalent to average solar irradiation at mid-latitudes (such as in Europe or the USA). To ensure reliability and control during testing of solar cells, a solar simulator can be used to generate consistent radiation. AM0 and AM1.5 solar spectrum.

How efficient are solar cells?

Now, silicon solar cells represent 40 % of the world solar cells production and yield efficiencies well higher than 25 % (A. Wang et al 1990). In solar technology, the main challenge of researchers is to improve solar cells efficiency.

How efficient are amorphous silicon solar cells?

Amorphous silicon solar cells generate 15 mA/cm2 density of current and the voltage without connected load is above 800 mV. The efficiency is between 6 and 8% (S. W. Glunz et al. 2006). But, all solar cells require a light absorbing material contained within the cell structure to absorb photons and generate electrons (G. Sissoko et al. 1996).
