The production of silicon feedstock and wafers is energy intensive and the costs of the wafers are a significant part of the total module costs. The application of thinner wafers and cells is a way to an improved environmental profile (lower CO2 footprint and energy payback time) and save Si material costs. We present here the results of a...

IBC Solar cell process was developed based on the same process equipment as used for the Yingli N-type Panda Si solar cell technology. Recombination at surface and metal contact areas as well as contact resistivity were investigated and optimized to get a balance between Voc and FF. Moreover, the IR characteristics at -10V shown homogeneous...

Foil-based back contact module interconnection technology (FBC) is a versatile solution for high-performance all back contact modules. We exploit the advantages of FBC to make full size modules replacing Cu with lower cost Al. Characterization shows that these modules have excellent electrical performance and reliability. The pick and place...

We present a back junction back contact cell with small isolated BSF island߿ݠareas, surrounded by emitter area. This is an alternative for the more common IBC cell with interdigitated fingers. The optimal cell lay-out was determined by device simulations. We used discontinuous emitter and BSF contacts, which we connected through floating metal...

Back contact cells architectures, especially Interdigitated Back Contact (IBC), offer the potential for the highest efficiencies, best aesthetics, and application flexibility. Foil-based back contact module interconnect for these architectures has been shown to be a high throughput, industrially viable, and reliable solution for both IBC and...

Diffused IBC solar cells based on non-fire-through (NFT) metallization can achieve higher performance with respect to FT metallization, thanks to lower contact resistance. Less resistive contacts allows for lower metal fraction and thus lower contact recombination. For the application of NFT contacts, the rear side dielectric passivation layer...

Together with Yingli Solar and Tempress Systems, ECN accelerates the development of the Mercury IBC technology by implementing its low-cost cell process in a mass production environment. The Mercury solar cell concept based on a bifacial IBC cell design with a front floating emitter (FFE) can now be fully processed on Yinglis pilot line. Pilot...

An integral solar cell and module concept is developed based on an IBC cell design with a front floating emitter (FFE). The FFE renders the cell resilient to electrical shading and reduces the demands on feature size. The cells are bi-facial by design. We interconnected 6” IBC cells using a conductive back sheet foil, resulting in a visually...

In this paper we present the results of a study of the emitter contact properties of the Mercury cell, which is an n-type IBC cell with a front floating emitter. We found that contact recombination becomes higher and contact resistance becomes lower with higher firing temperature. Additionally, the contacts to light and heavy emitters were...

IBC cells with Front Floating Emitter (FFE) pose different design challenges compared to more conventional IBC cells with FSF (Front Surface Field). The FFE enables hole transport over distances that are large compared to the typical BSF or emitter width. The core of the cell design is commonly a device simulation in which, because of the...

We present Terahertz (THz) transmission measurements with a spatial resolution of down to 10 ?ѭ as a new inspection technique for high-resolution sheet resistance (Rsh) measurements, that are well suited to quantify the local Rsh (n-type and p-type regions) of interdigitated back-contact (IBC) structures and to support further optimization of...

In this paper we have presented an overview of the recent reliability results obtained at ECN for foil-based p-MWT, and novel high-efficiency n-MWT and IBC back-contact modules. As deduced from extensive TC and DH testing on p-MWT modules, two alternative low-cost conductive back sheet foils were shown to improve the module reliability. Exposure...

Standard characterization techniques such as LBIC are difficult to apply to IBC solar cells with a front floating emitter (FFE). This is because the cells need to be under bias illumination, and this is often impossible in commercial LBIC measurement tools. To the best of our knowledge, LBIC measurements on FFE IBC cells have not been published...

We show how to construct an equivalent circuit for our Mercury FFE IBC cells to model features beyond the unit cell efficiently, taking into account the lateral hole transport in the FFE. We show how its predictions can be correlated with voltage maps of the FFE voltage, and used for optimum design of for instance busbars. The highest efficiency...
