A critical analysis on the role of back surface passivation for a-Si/c-Si heterojunction solar cells
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Conference lecture
Restricted access - publisher's policyBack surface passivation is a well-known method to reduce carrier recombination and hence improves the efficiency of crystalline silicon solar cells. In this manuscript, we critically analyze the role of this process for ... -
Base contacts and selective emitters processed by laser doping technique for p-type IBC c-Si solar cells
(2015-08-28)
Article
Open AccessAbstract In this work, we describe a novel fabrication process of p-type interdigitated back contact (IBC) silicon solar developed by means of laser doping and laser firing techniques. We use dielectric layers both as ... -
Desarrollo de tecnologías de baja temperatura para la fabricación de células solares de heterounión de silicio
(Universitat Politècnica de Catalunya, 2015-07-23)
Doctoral thesis
Open AccessEl desarrollo de la tecnología fotovoltaica de silicio cristalino ha llegado al punto en que la mejora de los dispositivos pasa, no tanto por un aumento de la eficiencia, como por la reducción del coste de fabricación. En ... -
Emitter formation using laser doping technique on n- and p-type c-Si substrates
(2015-05-01)
Article
Open AccessIn this work laser doping technique is used to create highly-doped regions defined in a point-like structure to form n+/p and p+/n junctions applying a pulsed Nd-YAG 1064 nm laser in the n ... -
Laser Induced Forward Transfer for front contact improvement in silicon heterojunction solar cells
(2015-05-01)
Article
Open AccessIn this work the Laser Induced Forward Transfer (LIFT) technique is investigated to create n-doped regions on p-type c-Si substrates. The precursor source of LIFT consisted in a phosphorous-do ... -
Low surface recombination in silicon-heterojunction solar cells with rear laser-fired contacts from aluminum foils
(2015-05-01)
Article
Open AccessIn this study, an approach to create laser-fired contacts from aluminum foils is studied on p-type silicon-heterojunction solar cells. This alternative approach consists of the use of aluminum foils instead of evaporated ... -
Main properties of Al2O3 thin films deposited by magnetron sputtering of an Al2O3 ceramic target at different radio-frequency power and argon pressure and their passivation effect on p-type c-Si wafers
(2016-11-30)
Article
Open AccessIn this work, 50-nm thick Al2O3 thin films were deposited at room temperature by magnetron sputtering from an Al2O3 ceramic target at different RF power and argon pressure values. The sputtering technique could be preferred ... -

Optimization of laser processes for local rear contacting of passivated silicon solar cells
(2014-01-31)
Article
Restricted access - publisher's policyLaser Firing Contact (LFC) and Laser Doping (LD) have become potential alternatives to the Al BSF thermal processing conventionally used in p-type c-Si solar cell rear contacts. Optimized LFC and LD processes allow, not ... -
Recovery of indium-tin-oxide/silicon heterojunction solar cells by thermal annealing
(2014-01-31)
Article
Restricted access - publisher's policyThe emitter of silicon heterojunction solar cells consists of very thin hydrogenated amorphous silicon layers deposited at low temperature. The high sheet resistance of this type of emitter requires a transparent conductive ... -

Study of the surface recombination velocity for ultraviolet and visible laser-fired contacts applied to silicon heterojunction solar cells
(2015-07-01)
Article
Open AccessIn this study, we investigate the effect of the laser-firing process on the back surface passivation of p-type silicon heterojunction solar cells. For that purpose, two different nanosecond laser sources radiating at ... -
Surface passivation and optical characterization of Al2O3/a-SiCx stacks on c-Si substrates
(2013-11-06)
Article
Open AccessThe aim of this work is to study the surface passivation of aluminum oxide/amorphous silicon carbide (Al2O3/a-SiCx) stacks on both p-type and n-type crystalline silicon (c-Si) substrates as well as the optical characterization ... -
