“…This confirms the validity of our model. In the previous work, Monestier [Monestier et al, 2007]] modeled J SC and found that the predicted J SC is larger than the experimental data, especially for the thickness larger than 180 nm. They attributed this to the thickness dependence of optical constants.…”

“…4 Photocurrent reaches theoretical values as high as 13 mA/ cm 2 , which is 35% larger than the largest short circuit current simulated in the same way for P3HT:PCBM blends. 15 Short circuit current losses in the 3:1 blend are evaluated to 31%, which is lower than for other compositions but still limiting the measured short circuit current.…”

Molecular blends of pentacene: N, N′-ditridecylperylene-3, 4, 9, 10-tetracarboxylic diimide (PTCDI-C13H27) permit to cover the visible part of the solar spectrum with an absorption onset at 730nm. Although charge mobilities of pentacene and PTCDI are rather large, the efficiency of pentacene:PTCDI-C13H27 blended devices is still lower than that of poly(3-hexylthiophene):[6,6]-phenyl C61-butyric acid methyl ester devices. Comparisons between experimental results and optical modeling indicate that more than 30% of the photocurrent is lost in the blend while the short circuit current should reach 13mAcm−2 in the absence of recombination processes.

“…If the surfaces are not passivated well then the decrease of current can be significant. However, even if we assume a value of 10 7 cm/s for surface recombination velocity, which is the maximum limiting value for most semiconductors [31,[34][35][36][37], we find that J sc is 9.53 mA/cm 2 for PCBM and 13.67 mA/cm 2 for CIGS layers so that total J sc is still 9% greater than the ideal total J sc of the solar cell without the intermediate layer. Although the light absorption is greater in PCBM than in CIGS, we note that the J sc is greater in CIGS than in PCBM.…”

“…Although the light absorption is greater in PCBM than in CIGS, we note that the J sc is greater in CIGS than in PCBM. The coulombic interaction between electrons and holes in organic material PCBM is much greater than that in direct bandgap inorganic material CIGS, which contributes to a significantly smaller carrier mobility in PCBM than that in CIGS [34,35]. As a result, the J sc in PCBM is smaller than that in CIGS despite a greater amount of photon absorption in PCBM.…”

Although ultra-thin-film solar cells can be attractive in reducing the cost, they suffer from low absorption as the thickness of the active layer is usually much smaller than the wavelength of incident light. Different nano-photonic techniques, including plasmonic structures, are being explored to increase the light absorption in ultra-thin-film solar cells.More than one layer of active materials with different energy bandgaps can be used in tandem to increase the light absorption as well. However, due to different amount of light absorption in different active layers, photo-generated currents in different active layers will not be the same. The current mismatch between the tandem layers makes them 1 ineffective in increasing the efficiency. In this work, we investigate the light absorption properties of tandem solar cells with two ultra-thin active layers working as two subcells and a metal layer with periodically perforated holes in-between the two subcells. While the metal layer helps to overcome the current mismatch, the periodic holes increase the absorption of incident light by helping extraordinary optical transmission of the incident light from the top to the bottom subcell, and by coupling the incident light to plasmonic and photonic modes within ultra-thin active layers. We extensively study the effects of the
