The p-type crystalline silicon wafers have occupied most of the solar cell market today. However, modules made with n-type crystalline silicon wafers are actually the most efficient modules up to date. This is because the material properties offered by n-type crystalline silicon substrates are suitable for higher efficiencies. Properties such as the absence of boron-oxygen related defects and a...
Our primary goal is to increase the stabilized efficiency of thin film silicon solar cells in the substrate (nip) configuration by using textured substrates and tandem structures, based on amorphous (a-Si:H) and microcrystalline silicon (μc-Si:H). In order to reduce costs of mass-produced thin film solar modules, special attention has been paid in developing processes compatible with plastic fo...
Commercial aluminium and stainless steel sheets were used as substrates for thin film silicon solar cell deposition. The influence of elemental contamination and disturbed film growth on solar cell performance and yield were studied. Diffusion during film growth was found to be more pronounced than thermally activated interdiffusion of existing films. Surface irregularities of the substrate are...

In this paper, we will present a Pc1D numerical simulation for heterojunction (HJ) silicon solar cells, and discuss their possibilities and limitations. By means of modeling and numerical computer simulation, the influence of emitter-layer/intrinsic-layer/crystalline-Si heterostructures with different thickness and crystallinity on the solar cell performance is investigated and compared with ho...
Chemical and crystallographic defects are a reality of solar grade silicon wafers and industrial production processes. Long overlooked, phosphorus as a dopant in silicon wafers is an excellent way to mitigate recombination associated with these defects. This paper details the connection between defect recombination and solar cell terminal characteristics, for one specific case of high hole life...
A new device called “Solant” (for SOLar cell – ANTenna) is presented in this paper. It is a combination of thin-film amorphous silicon solar cells and flat printed antennas. A proton irradiation campaign has also been carried out on a series of n-i-p amorphous and p-i-n micromorph [microcrystalline (μc-Si:H) and amorphous (a-Si:H)] silicon tandem solar cells. The effect of thermal annealing on ...
Two different techniques for the electronic surface passivation of silicon solar cells, the plasma-enhanced chemical vapour deposition of silicon nitride (SiN) and the fabrication of thin thermal silicon oxide/plasma SiN stack structures, are investigated. It is demonstrated that, despite their low thermal budget, both techniques are capable of giving an outstanding surface passivation quality ...
This work demonstrates the fabrication of silicide/silicon based solar cell towards the development of low cost and environmental friendly photovoltaic technology. A heterostructure solar cells using metallic alpha phase (α-phase) aluminum alloyed iron silicide (FeSi(Al)) on n-type silicon is fabricated with an efficiency of 0.8%. The fabricated device has an open circuit voltage and fill-facto...
— This paper review the present technologies for the fabrication of solar cells and modules based on the most common semiconductors namely silicon, CuInGaSe(S) and CdTe materials as well as on III-V concentrated photovoltaic cells and modules. For silion technology, we give insights on the growth of monocrystalline and multicrystalline silicon wafers and then we describe the most common solar c...
