Co-Diffused Back-Contact Back-Junction Silicon Solar Cells

2013
Aiming for industrial solar cell fabrication the ratio of costs to watt peak has to be lowered [1]. This can be achieved by either decreasing the overall solar cell manufacturing costs including material, process and module assembly or increasing solar cell efficiency [2].

Inspection of Back Surface Aspheric Contact Lenses

Optometry and Vision Science, 1979
Two methods of clinically inspecting and verifying rigid back surface aspheric contact lenses were investigated. A modification of the Radiuscope was found to be an accurate method for making such measurements. Measurement data of a number of aspheric lenses obtained by using this procedure are presented.

Verification of Aspheric Contact Lens Back Surfaces

Optometry and Vision Science, 2003
To suggest a tolerance level for the degree of asphericity of aspheric rigid gas-permeable contact lenses and to find a simple method for its verification.Using existing tolerances for the vertex radius, tolerance limits for eccentricity and p values and were calculated.

Large-Area Back-Contact Back-Junction Solar Cell With Efficiency Exceeding 21%

IEEE Journal of Photovoltaics, 2012
In this study, high-efficiency solar cells are presented with the use of low-cost industrially available technologies. This results in the so-called ZEBRA concept: a litho-free process in which standard 156 × 156 mm2 monocrystalline n-type Cz-Si wafers are processed into high-efficiency interdigitated back-contact solar cells.

Efficiency of Back Contact-Back Junction Solar Cells with Variable Contact in the Emitter

2018
As renewable energy becomes more sustainable and more viable than it has ever been, more and more countries are turning ‘green’ and reverting to sustainable ways. We have carried out the study of a cell Back Contact - Back Junction (BC-BJ) solar cell with an alone contact in the issuer who has as efficiency of 22.027%.

Back Contact Dye-Sensitized Solar Cells

Japanese Journal of Applied Physics, 2007
A new structure for dye-sensitized solar cells (DSCs) was proposed in which the transparent conducting oxide (TCO) is omitted and the cathode is located on the opposite side of the titanium dioxide (TiO2) film surface to the side of light irradiation. DSCs with this structure are called back contact DSCs (BCDSCs).

Laser-Doped Back-Contact Solar Cells

IEEE Journal of Photovoltaics, 2015
We present laser-doped interdigitated back-contacted solar cells with a record efficiency $\bm{\eta}$ = 22.0%. The high versatility and spatial resolution of our laser doping process enable local n-type and p-type doping with a precision below 30 $\mu \hbox{m}$ and avoid any masking for doping.

Characterizing Local Contact Resistances of Interdigitated Back Contact Silicon Solar Cells

2014
Next generation high efficiency interdigitated back contact (IBC) silicon solar cells are often designed with complex doping and contacting structures that are sensitive to series resistance induced losses. Particularly local contact resistance problems present a major fill factor loss in industrially feasible solar cell designs.

[Bringing back scleral contact lenses].

Journal francais d'ophtalmologie, 2005
Although old generations of scleral contact lenses were totally replaced by soft and hard contact lenses, new designs and materials have recently allowed the successful use of nonfenestrated scleral contact lenses in patients who are intolerant to regular contact lenses.

Back‐contact solar cells: a review

Progress in Photovoltaics: Research and Applications, 2005
AbstractEver since the first publications by R.J. Schwartz in 1975, research into back‐contact cells as an alternative to cells with a front and rear contact has remained a research topic. In the last decade, interest in back‐contact cells has been growing and a gradual introduction to industrial applications is emerging.
