Bifacial Solar Cell

Bifacial solar cell is a specially designed solar cell for the production of electricity from both sides of the solar cell. It is an active field of research to make photovoltaics (PV) more competitive by increasing its efficiency and lowering its costs. We developed an n+pp+ structure for the bifacial solar cell. The fabrication used phosphorus-oxy-trichloride (POCl3) diffusion to form the emitter and Al diffusion using conventional screen printing to produce the back surface field (BSF). The n+pp+ bifacial solar cell was a sandwiched structure of antireflective coatings on both sides, Argentum (Ag) as a front contact and Argentum/Aluminum (Ag/Al) as a back contact. This paper reports the solar cell performance with different surface passivation or antireflecting coatings (ARC). Silicon nitride (SiN) deposited by Plasma-Enhanced Chemical Vapor Deposition (PECVD), thermally grown silicon dioxide (SiO2), PECVD-SiO2, and SiO2/SiN stack were used as ARC. The efficiency obtained for the best bifacial solar cell having SiN as the ARC is 8.32% for front surface illumination and 3.21% for back surface illumination.

In this paper, we report one bifacial p-type PERC solar cell with efficiency over 22% using laser doped selective emitter produced in larger-scale commercial line on 6-inch mono-crystalline wafer. On front side of the solar cell, square resistance of p-n junction was found to be closely related with laser power at certain laser scan speed and frequency. On the other side, the rear fingers with different ratios of height and width and rear silicon nitride (SiNx) layer with different thickness were optimized, and a highest rear efficiency of the bifacial solar cell was obtained. Finally, bifacial silicon solar cells with the front and rear efficiencies exceeding 22% and 15% (AM1.5, 1000 W/m2, 25 °C) were successfully achieved, respectively.

Bifacial Solar Cell

Surface passivation is the most significant step to keep the recombination loss at a tolerable minimum and avoid an unacceptably large efficiency loss when moving towards thinner silicon material. In this study, the modification and photosensitization on back surface field (BSF) of bifacial solar cell was investigated by using dye molecules nanostructure namely DiO. The DiO dye molecules nanostructure was passivated on SiNW and BSF layers using spin-coating method. The energy gaps of DiO dye are 2.14 eV (DiO in chloroform), 2.13 eV (DiO on silicon nanowire (SiNW)) and 2.12 eV (DiO on BSF). The time resolved photoluminescence increased with the DiO dye coated on SiNW ( 14Ï„">  = 1.24 nm) and BSF layers ( 14Ï„">  = 0.93 nm) compared to DiO dye in chloroform ( 14Ï„">  = 0.54 nm). The light trapping inside the interface layers of DiO dye/silicon indicating a slow process of charge recombination before its reach equilibrium states, it is due to interface interaction bonding within boundary layers and dye molecules nanostructure. The short circuit current density also increased about 25% from 4.44 to 5.56 mA/cm2 when applying the dye molecules nanostructure on BSF of the cell. Collection of photo carrier lead of internal and external quantum efficiency improved about 19% and 25%, respectively, is mainly due to energy transported to the junction. The photo-generated electron on DiO dye lead to improvement in the exciton dissociation efficiency leading to increase in the electrical properties.
