Basic schematic of a silicon solar cell. The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market.
The top layer is referred to as the emitter and the bulk material is referred to as the base. Bulk crystalline silicon dominates the current photovoltaic market, in part due to the prominence of silicon in the integrated circuit market. As is also the case for transistors, silicon does not have optimum material parameters.
1. Introduction Silicon interdigitated back contact (IBC) solar cell conception was first proposed by Lammert and Schwartz in the 1970s,[1,2] and now is one of the research hotspots of high-ef ciency solar cells. The most obvious advantage of IBC solar fi cells is that metal fingers and busbars are completely removed to the back side.
The concentration of the electrons and holes in the silicon layer of the c-Si solar cell is modified and optimized by the process of doping. The doping concentration and the type of doping (shallow or deep) influences the electrical conductivity of the semiconductor material making the solar cell more efficient.
An increase of 4 mV in Voc, 0.2 mA/cm2 in short-circuit current Jsc and 0.2% absolute increase in efficiency is achieved for solar cells using a LDE compared to solar cells with our standard emitter profile.
Particularly, the peak surface concentrations for the simulated profiles are overestimated, which might reduce the cell potential. The concentration of the electrons and holes in the silicon layer of the c-Si solar cell is modified and optimized by the process of doping.
