Can solar cells become a mainstream technology for large-scale applications?

Solar cells can become the mainstream technology for large-scale applications only when they are competitive in price and performance, with a long service life and low attenuation rate . A major task of solar cells is to solve the above-mentioned problems and simplify the preparation process in order to minimize the cost. 2. TOPCon solar cell

How does thermalization loss affect a single-junction solar cell?

After reviewing the fundamental losses of single-junction solar cells, it was shown that thermalization loss and below-bandgap (Eg) loss have a major impact. The below-bandgap loss is about 25% and the thermalization loss is about 29.8% for a material having a bandgap of 1.31 eV.

How do dominant losses affect solar cell efficiency?

Dominant losses and parameters of affecting the solar cell efficiency are discussed. Non-radiative recombination loss is remarkable in high-concentration-ratio solar cells. Series resistance plays a key role in limiting non-radiative recombination loss.

How do solar cells circumvent transmission and thermalization losses?

The book describes emerging strategies to circumvent transmission and thermalization losses in solar cells, and thereby redefine the limits of solar power conversion efficiency. These strategies include the use of organic molecules and rare-earth metal materials.

Why do photons remain unabsorbed in a solar cell?

5.1.1. Below E g loss Photons with energies below the bandgap remain unabsorbed in a solar cell due to the mismatch between the broad solar spectrum and the specific energy absorption characteristic of a single bandgap (Eg) (Dupré et al., 2016).

How to reduce recombination loss in a photovoltaic system?

Increasing the absorption angle is a commonly used method to suppress this loss process. Non-radiative recombination loss and series loss are extremely significant for the high-concentration-ratio photovoltaic system, covering 15%–40% of the total incident solar energy for the cells with bandgap below 2.0 eV in the case of 100 suns.
