1 Introduction. The efficiency of perovskite solar cells (PSCs) dramatically increases from 3.8% [] for the first time in 2009 to the current 26.1% (certified), [2, 3] which is already close to the 26.1% of single crystal (non-concentrator) silicon solar cells, in only about 10 years, far less than the time (nearly 40 years) it takes to reach a similar level in silicon solar cells.
CONCLUSIONS A simple theoretical model to calculate the effective surface recombination velocity of an arbitrary high-low junction allows to design high-low junctions for solar cells.
Recently the use of high-low junctions on illuminated surfaces has been proposed to reduce the surface recombination velocity. High efficiencies can be obtained with the High-Low Emitter Solar Cell [7, 8], the Double Sided Surface Field Cell and the Front Surface Field Solar Cell .
While low-cost solar cell materials are desirable for tandem solar cells, only high-voltage junctions, as quantified by the ERE, 26,146 with well-chosen bandgaps matched to the application spectra will be helpful for surpassing the efficiency of single-junction silicon.
Because state-of-the-art efficiencies of single-junction solar cells are approaching the Shockley-Queisser limit, the multi-junction (MJ) solar cells are very attractive for high-efficiency solar cells. This paper reviews progress in III–V compound single-junction and MJ solar cells.
Hence, many important organizations of research spent their money to design the projects of III–IV semiconductor MJ solar cells. The most prosperous sustainable root of energy is the sunlight, affecting the surface of earth each day, having intensity of almost 0.1 W/cm 2 and in excess of 15,000 exajoules (EJ) .
Without adjusting the design of solar cell, the open-circuit voltage greater than 2 V is obtained to increase the performance of double junction . The positions and lattice parameters of upper and lower cells should be carefully matched in the material to decrease the mismatch dislocations in lattice-matched solar cells.

The perovskite solar cells were derived from dye-sensitized solar cells, which was initially developed by Grätzel et al. In 2009, Kojima et al. firstly replaced the light absorbing organic dyes with the perovskites of MAPbBr 3 and MAPbI 3 in the dye-sensitized solar cells, resulting in the first solar cells based on perovskites with power conversion efficiency of 3.8%. …
