For solar cells with bandgap E g varying from 1 eV to 3 eV, we can see the main energy losses consist of the below E g loss, the thermalization loss and the angle mismatch loss. And all these three kinds of losses contribute to heat generation, causing a significant temperature rise, which greatly limits the efficiency of solar cells. The concentration ratio (or Ω a), series
In photovoltaic solar cells, several energy losses are related to device electronic properties, including contact voltage loss, recombination loss, and junction loss [1, 2] sides, there are two more primary loss mechanisms linked to photon harvesting, that is, thermalization loss of above-bandgap photons and transmission loss of sub-bandgap photons
Tandem solar cells and downconversion cells such as singlet fission solar cells are both solving the same problem: the thermalization losses for high-energy photons in single-bandgap solar cells. They do so, however, in fundamentally different ways. The tandem solar cell essentially consists of two individual cells that are connected in series, or electrically
A tandem solar cell consists of a silicon bottom cell and a perovskite top cell. Perovskite absorbs blue light (high-energy photons) best, whereas silicon absorbs red light (low-energy photons).

According to a book by Fonash S (Parnis and Oldham, 2013)., solar energy conversion involves four essential processes: 1) light absorption, 2) generation of electron-hole pairs, 3) selective transport of charges, and 4) recombination of electrons and holes, ultimately restoring the absorber to its ground state.
