Theory of the Solar Cell. There are different scales of solar cell products and technologies, and it''s essential to understand some of the terms used in research and industry.

Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].
Multijunction solar cells offer a path to very high conversion efficiency, exceeding 60% in theory. Under ideal conditions, efficiency increases monotonically with the number of junctions. In this study, we explore technical and economic mechanisms acting on tandem solar cells.

How much do multi-junction solar cells cost? Cost of multi-junction solar cells are difficult to estimate, owing to the variance in the number of cells considered, and also owing to the nascent nature of this sector. However, it can be safely said that as of 2014, multi-junction solar cells cost at least 2-2.5 times as much as single junction

Multi-junction solar cells structure is multi-layers of single-junction solar cells on top of each other. Band gap of the materials form the top to the bottom going to be smaller and smaller.
A multi junction solar cell (MJSC) has already been demonstrated as the answer. A MJSC uses multiple p-n semiconductor junctions connected in series to absorb different wavelength ranges of the solar spectrum enabling light conversion efficiencies which surpasses the theoretical S-Q limit (Nikoletatos and Halambalakis, 2018).
Single junction solar cells are limited by the S-Q limit at a maximum efficiency of approximately 33%. MJSCs are proven to be the champion among all the solar cell technologies both in laboratory and module scale with the use of multiple semiconductor absorbers to attain record efficiencies.
More precisely, the multi-junction concept is modeled using the interfacial voltage aspect, where a generalized approach is proposed to model the solar cell electrical behavior. Moreover, we show the versatility of the developed model to deal with the solar cell performance whatever the materials and number of junctions are.
The output current of the multijunction solar cell is limited to the smallest of the currents produced by any of the individual junctions. If this is the case, the currents through each of the subcells are constrained to have the same value.
A current record efficiency of 40.7%, achieved with a triple-junction version of the cell, corresponds to less than a half of the maximum theoretical limit efficiency of 86.8% . By the contrast, efficiencies of single-junction solar cells are almost reached their potential limits.
