AI Customer ServiceConceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.
High-efficiency solar cells are demanded by all applications of photovoltaics, including terrestrial and space power generation, thermal energy conversion via thermophotovoltaics, and transmission via laser power conversion.
The power conversion efficiency (PCE) has been enhanced dramatically from ~2–3 to ~12 % through materials, interface and device architecture innovations such as tandem. This chapter focuses on multi-junction or tandem solar cell which is the architecture for highest solar cell efficiency.
The basic theory and characterization of c-Si heterojunction solar cells, including charges separation and carrier selectivity formation, carrier recombination and minority carrier lifetime in c-Si, parameters of solar cells, and related characterization techniques, are briefly presented in Section 2.
As state-of-the-art of single-junction solar cells are approaching the Shockley–Queisser limit of 32%–33%, an important strategy to raise the efficiency of solar cells further is stacking solar cell materials with different bandgaps to absorb different colors of the solar spectrum.
They use semiconductors as light absorbers. When the sunlight is absorbed, the energy of some electrons in the semiconductor increases. A combination of p-doped and n-doped semiconductors is typically used to drive these high-energy electrons out of the solar cell, where they can deliver electrical work before reentering the cell with less energy.
