“…As organic solar cells are achieving efficiencies and lifetimes closer to the minimum required for commercialization, there is the need to study different modulus disposition, size, electrical connections, and individual cell behavior [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. While high efficiency modules have been reported, these (as a rule of thumb) only seem to occur on small-scale laboratory devices.…”

Organic solar cell efficiency is known to be active area dependent and is usually a problem in the upscale factor for market applications. In this work, a detailed study of organic photovoltaic devices with active layer based on poly(3-hexylthiophene) (P3HT) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C 61 (PCBM) is made, evaluating the effect of the change on the active area from 10 −2 to 4 cm 4 . The device structure was kept simple in order to allow the understanding of the physical effects involved. Device figures of merit were extracted from the equivalent circuit using a genetic-based algorithm, and their relationship with the active area was compared. It is observed that the efficiency drops significantly with the active area increase (as the fill factor) while the parallel and series resistance, adjusted to the active area, seems to be relatively constant and increases linearly, respectively. The short circuit current and the generated photocurrent also drop significantly with the active area increase. The open circuit voltage does not show major changes. These results are discussed considering the main influences for the observed efficiency data. Particularly, as the basic circuit model seems to fail to explain the macroscopic results, the behavior can be related with the enlargement of defect interaction.

“…It is very important to improve the power conversion efficiency (PCE) and reduce the cost for greatly accelerating the commercialization of solar cells. Organic solar cells (OSCs) and organic-inorganic hybrid perovskite solar cells (PSCs), as the third-generation solar cells, are attracting much attention due to their potentials as the low-cost, flexible and lightweight sources of renewable energy, as well as matching with high-output, large-scale roll-to-roll (R2R) printing techniques [4][5][6][7][8]. The PCEs of the state-of-the-art OSCs has reached over 10.0%, resulting from the progress in new materials, device engineering, device physics, etc.…”

Organic solar cells (OSCs) continuously attract much attention due to their potentials as the low-cost and lightweight sources of renewable energy, and the power conversion efficiency (PCE) of the state-of-the-art OSCs has reached over 10.0%. Especially, there has been an unexpected breakthrough and rapid evolution of highly efficient organic-inorganic hybrid perovskite solar cells (PSCs), and the PCE has been improved to over 20%. The interface plays a very important role on the performance of both OSCs and PSCs, as well as their stability. It is imperative to control the interface properties and understand the mechanisms for obtaining highly efficient OSCs and PSCs. In this review, we will summarize our research progress on the interface modification of OSCs and PSCs using the electron transport layer and hole transport layer, as well as the molecular template layer.

A hybrid process including roll-to-roll (R2R) gravure printing, via-hole printing, and electroless plating was investigated for the creation of a double-side flexible printed circuit board (FPCB). A R2R gravure process with an Ag seed layer that includes front-and back-side printing with a polyimide film at the center was investigated. The gravure-printed Ag pattern was laser drilled for high accuracy. A via hole was filled with a low-viscosity Ag ink using the drop-casting method. In addition, an electroless Cu plating process was performed to increase the conductivity of the printed circuit. The interconnection performance was confirmed from the resistance values obtained using a feed-through test and microscopic images. To evaluate the reliability of the FPCB, a cyclic bending motion test was performed; stable electrical performance was observed even after 400,000 cycles. The results obtained in this study suggest that the proposed hybrid process for double-side FPCBs is viable for a mass production system.
