Nanopillar arrays of mesoporous Bi2Se3 and CuInSe2 in layer‐based perovskite solar cells

“…Moreover, the MP structure is generally considered to be a hybrid structure [24]. Over the last decades, the alloys of Cu (In 1-x , Ga x )Se 2 (CIGS) have been considered important semiconductor light absorbers for thinfilm photovoltaics and correspondingly low-cost technology [25], which can be used for efficient conversion of solar energy into electricity [26] with high absorption coefficients ranging from 10 5 cm −1 to 2:9 � 10 5 cm −1 [27], a direct band-gap energy of 1.04 eV [28,29], high mobility of minority carrier electrons µ e ¼ 300 to 700 cm 2 V −1 s −1 and holes µ h ¼ 10 to 30 cm 2 V −1 s −1 [30], and low toxicity [25]. These types of materials have been used in solar cells based on polymers, PSCs, ternary hybrid solar cells [26], and classic crystalline photovoltaic materials (Si and GaAs) [31].…”

A qualitative Design and optimization of CIGS-based Solar Cells with Sn2S3 Back Surface Field: A plan for achieving 21.83 % efficiency

“…Furthermore, the efficiency of 24.45 % has been achieved by adding a SnS BSF layer of thickness 0.3 μm [ 30 ]. On the other hand Imam et al develop the efficiency of 26.1 % [ 31 ], 30 % [ 32 ], 35.6 % [ 33 ], and 37.1 % [ 34 ] with using different types of CIGS based tandem cell.…”

Effect of Temperature on the Performance of CGS/CIGS Tandem Solar Cell

“…The concept of tandem solar cells are the devices with two or more absorber layers with different bandgaps to absorb the maximum wavelength of the solar spectrum [12]. Tandem solar cells are combined with a narrow-bandgap bottom cell to absorb longwavelength photons and awide-bandgap top cell to absorb the short-wavelength photons of solar spectrum energy [13][14][15].Because of the series connection, the efficiency of the tandem solar cell is limited by the solar cell that issues the lower current. An equal current criterion, among the cells building the tandem, must be achieved; all the cells must have the same photocurrent (current matching) [3,4,7,14].…”
