A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.
Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.
Besides these limitations for the open circuit voltage, PL can also make predictions concerning the fill factor of the solar cell. An increased diode factor decreases the fill factor. The diode factor of the absorber alone can be measured by intensity dependent PL. The exponent of the power law is the optical diode factor.
For H = 15 μm, the MAPD shows a maximum variation of 0.25 mA / cm2 over the 1700–3200 nm lattice constant range. The light-trapping performances of 15–20 μm -thick inverted PhC solar cells are extremely robust with respect to lattice constant variation.
The efficiency of solar cells depends on the photocurrent, on the open circuit voltage and on the fill factor, which in turn depends on the diode factor.
During the development of solar cells or in industrial production, it is desirable to know already the quality of the absorber alone. Photoluminescence (PL) measurements of the absorber can provide information about the open circuit voltage and the fill factor, which the absorber is able to produce when made into a solar cell.
