This paper presents a method for determining the optimum active-area width (OAW) of solar cells in a module architecture. The current density-voltage curve of a reference cell with a narrow active-area width is used to reproduce the current density profile in the test cell whose active area width is to be optimized. We obtained selfconsistent current density and electric potential profiles from iterative calculations of both properties, considering the distributed resistance of the contact layers. Further, we determined the OAW that yields the maximum efficiency by calculating efficiency as a function of the activearea width. The proposed method can be applied to the design of the active area of a dyesensitized solar cell in Z-type series connection modules for indoor and building-integrated photovoltaic systems. Our calculations predicted that OAW increases as the sheet resistances of the contact layers and the intensity of light decrease.

“…Let us apply the proposed method to determine the OAW of the DSCs in a Z‐type series connection where the front and rear contact layers have the same sheet resistance. The fabrication of the DSCs for this study was detailed elsewhere , . The reference cell had an active area of 0.4 × 0.5 cm 2 .…”

“…To generate a high level of current instead, cells have to be connected in parallel and/or use highly conductive metallic grids to increase the conductance of the transparent conducting oxides (TCOs). For series interconnection schemes, “W,” “Z,” and “Monolithic” architectures represent the most utilized solutions to obtain efficient and integrated DSC photovoltaic modules . For W modules, an efficiency of 8.4% on 26.5 cm 2 aperture area has been reported .…”

“…have shown 100 cm 2 modules with a conversion efficiency of 6.3% on active area (47.5 cm 2 ), reaching 6.6% when using a scattering layer or a back reflector. The efficiency on aperture area was almost half of that on active area . The main factors that contribute to limit the performance on large‐area devices compared with small laboratory cells are the interconnections, the resistances arising from the transparent conducting oxides (TCOs), and the percentage of the substrate area occupied by the sealants and interconnections.…”

We have designed and fabricated dye solar cell (DSC) modules with optimized geometries and processes. Integrated interconnections were made following the Z architecture for series connections. Several modules were prepared varying the materials, multilayer combination of the TiO2 active layers, and the fabrication processes. With the best combination of TiO2 multilayers, titanium tetrachloride (TiCl4) treatment, a back reflector/diffusor, and optimized layout of cells via simulations, we fabricated a DSC module with a conversion efficiency of 6.9% on 43cm(2) aperture area and 9.4% on active area. This result confirms that an effective scale-up of high performance Z-series-connected DSC modules can be achieved comparable with other thin film technology. Note that the materials used to produce the devices of this work are all commercially available: an important result for a technology that is being developed for industrial application.

A process to fabricate a parallel connection dye-sensitized solar cell (DSSC) module has been developed using commercially available materials and screen printed silver grid. The process is not only simple but also easy to manipulate and therefore facilitates researchers in evaluating new materials in a module platform. By changing the design of the silver grid pattern, it was found that the performance of DSSC modules can be controlled. With the silver grid, DSSC modules have shown that a 7% conversion efficiency can be reached. Modules fabricated by this process, but with a non-volatile electrolyte system, passed a 60 C, 1000 h thermal aging test.
