silicon interdigitated back contact solar cellsSilicon interdigitated back contact (IBC) solar cells with front floating emitter (FFE-IBC) put forward a new carrier transport concept of "pumping effect" for minority carriers compared with traditional IBC solar cells with front surface field (FSF-...
Internal current-collection efficiencies greater than 90 percent and energy-conversion efficiencies of 18 percent at 30 suns have been measured on a laboratory version of the interdigitated back contact (IBC) solar cell. The quantum efficiency at 600 nm was greater than 90 percent which implies...
This work shows a novel fabrication process of interdigitated back-contacted c-Si(n) solar cells based on laser-doped point contacts. In this approach, all the highly-doped regions have been entirely fabricated through UV laser processing of dielectric layers, avoiding the high temperature steps...
A new interdigitated back contact silicon heterojunction (IBC-SHJ) solar cell with two additional buffer layers is investigated. The buffer layers are two thin p-type crystalline silicon (c-Si) layers placed at front and back surface of c-Si/a-Si:H hetero-junction interfaces. Improvement of...
A process of manufacturing the interdigitated back-contact solar cell, with the use of screen printing or spraying and the use of chemical etching, forms the trenches for the P-type electrode on the back of the substrate for making the solar cell. The time-consuming process of ...
solar cells combining interdigitated back contacts and an amorphous silicon/crystalline silicon heterojunction. The photoconversion efficiency is over 26% with a 180.4 cm2designated area, which is an improvement of 2.7% relative to the previous record efficiency of 25.6%. The cell was analysed...
A simulation of interdigitated back-contact silicon heterojunction (IBC-SHJ) solar cells was performed using a quantum transport model to consider the quantum effect at the crystalline/amorphous (c/a) heterojunction interface. It was found that the impact of the quantum effect on the open-circuit...
A chuck used for temporary contacting should feature at least one sense contact per busbar and pin contacting resistances below 30 mΩ in order to keep the fill factor error below 0.5% absolute. 展开 关键词: interdigitated back-contact (IBC) solar cell Current–voltage characteristics fill ...
We present our own Interdigitated Back Contact (IBC) technology, which was developed at ISC Konstanz and implemented in mass production with and at SPIC Solar in Xining, China, with production efficiencies of over 24%. To our knowledge, this is the highest efficiency achieved in the mass pro...
Solar cells with high AR, dense pitch, and trapezoidal front finger was developed to reduce optical shadowing effect and resistive loss. Precise doping control by IIP was done to make shallow front junction, selective contact field and back surface field passivation. Front base local contact by ...
