Outdoor exposure tests of a solar cell have been conducted at the University of Brunei Darussalam once a week for a period of six months. These data were used to estimate the efficiency η and fill factor FF of the solar cell using well known equations (1–12). The I–V curve is useful as any peculiarities in its shape may indicate the presence of a fault, which can then be

The high open‐circuit voltage arises from the injection and accumulation of excess majority carriers in the bulk upon illumination or application of forward bias to the structure. A working model for the cell, designated a back surface field (BSF) cell, is described, and recent developments are cited.

The forecasted eclipse of silicon wafer-based solar cells has not yet occurred, as presently about 90% or more of commercial solar cell products are still bulk silicon devices made from silicon cast ingots, pulled single-crystal boules, or ribbon/sheet. Solar cells made from bulk silicon have persisted due to continuing cost reductions realized by economies of scale, as well as

This applies as well to the quality and availability of single crystal silicon of high perfection. In semiconductor industry, more than 85 % of monocrystalline Si (mono-Si) material is grown based on Czochralski (Cz) method 5–7]. Therefore, in the first years only Cz grown mono-Si were used for solar cells. The growth principle of this method is shown in Fig. 1.2.

Magnetic field - Electrical characteristic correlation for a silicon solar cell (Si-SC) of n+ pp + structure was studied in the dark and illumination modes. In the dark, both the current and the voltage decreased with increasing the magnetic field in forward bias. However, in reverse bias, the behavior was quite different. Under illumination, the effect of magnetic field
3. Device physics of silicon solar cells 3.1 Silicon solar cells Commonly, most silicon solar cells are configured in N-P junctions or vice versa (S.M. SZE 1981) in one side and N +-N-P + structure (or vice versa) for double sides named bifacial silicon solar cell (S. Madougou et al. 2004, 2005a, 2005b, 2007a et 2007b). Silicon solar cells
In this paper, the effect of an external applied electric field on the thermodynamic efficiency of a silicon photovoltaic solar cell has been studied. Theoretically, it has been shown that an auxiliary applied electric field could be a very promising solution to reach a high efficiency of the solar cells.
Photovoltaics provides a very clean, reliable and limitless means for meeting the ever-increasing global energy demand. Silicon solar cells have been the dominant driving force in photovoltaic technology for the past several decades due to the relative abundance and environmentally friendly nature of silicon.
The best real-world silicon solar cell to date, developed by Kaneka Corporation, is able to achieve 26.7% conversion efficiency 7, 8. A loss analysis of this 165 μm -thick, heterojunction IBC cell shows that in absence of any extrinsic loss mechanism the limiting efficiency of such a cell would be 29.1% 7.
During recent years, a lot of effort has been taken to achieve the very limits for single junction silicon solar cells experimentally. The highest efficiencies reported so far are 26.7% for n-type and 26.1% for p-type [ 5] silicon solar cells.
This paper presents a possible solution to improve the efficiency of photovoltaic solar cells. An external electric field is applied on a silicon photovoltaic solar cell, inducing band-trap ionization of charge carriers. Output current is then monitored and the thermodynamic efficiency is calculated.
The efficiency of the solar cell lies in the range of 10.08% - 12.54%. The values of these efficiencies are 3% - 4.54% less than those supplied by the manufacturer and were measured at STC.
