Passivated emitter and rear cell (PERC) concept with an already developed roadmap for 24% efficiency will be leading the photovoltaics industry in the upcoming years. In a few industrial pilot lines, efficiencies above 22% have already been attained. Pilot lines have important roles in bridging lab scale proven concepts with the products which are ready for mass production. Therefore, GUNAM Photovoltaic Line which is specialized on PERC concepts has been established to overcome the barriers that hinder the performance of c-Si solar cells in PERC concepts in a relevant environment. The aim of this article is to show how a loss analysis can be employed in a practical way in an industrially relevant environment. The analysis depends on the first results of the studies from 6 months ramp up period of GPVL A batch of standard PERC type solar cells with p-type base and atomic layer deposited Al2O3 rear passivation have been fabricated during the ramp up of the line. A detailed gain-loss analysis was performed to address the optical, electrical and recombination losses in order to increase the cell efficiency.

Technical and economic assessment of fixed, single and dual-axis tracking PV panels in low latitude countries
Bahrami, Arian; Okoye, Chiemeka Onyeka; Atikol, Ugur (Elsevier BV, 2017-12-01)
This study aims to contribute towards developing a sustainable roadmap for electrification program via solar energy deployment in 21 low latitude countries (0-15 degrees N) with limited access to the grid. Firstly, the available electrical energy from fixed, single and dual-axis solar tracking PV panels is demonstrated using a case study of nine selected locations in Nigeria. The annual electrical energy for the locations from a fixed 1-kW PV panel tilted at an optimal angle ranges from 1485 to 2024 kWh, wi...
Simulation of silicon heterostructure solar cell featuring dopant-free carrier-selective molybdenum oxide and titanium oxide contacts
Mehmood, Haris; Nasser, Hisham; Tauqeer, Tauseef; Turan, Raşit (Elsevier BV, 2019-12-01)
Dopant-free carrier-selective transition metal oxide (TMO) contacts offer unique electrical properties pertaining to the rectification of doping-related issues in silicon (cSi) solar cell. In this paper, cSi heterojunction solar cell featuring TMOs of molybdenum oxide (MoOx) and titanium oxide (TiOx) as hole- and electron-selective contacts, respectively, has been realized using Silvaco TCAD. The photovoltaic performance has been evaluated based on the electron affinity of TiOx, its thickness, interfacial c...
Designing the C-GEN lightweight direct drive generator for wave and tidal energy
Keysan, Ozan; McDonald, Alasdair; Hodgins, Neil; Shek, Jonathan (Institution of Engineering and Technology (IET), 2012-05-01)
The C-GEN is a novel permanent magnet generator aimed at reducing overall system mass in direct drive power takeoff applications. The design of a C-GEN generator requires the combination of electromagnetic, structural and thermal models. Models used in the development of design tools applicable to both rotary and linear C-GEN generators are described in this study. The design tool is verified with the experiment results obtained from a 15 kW prototype. A genetic optimisation algorithm is developed combining...
Evaluation of hybridsolar-wind-hydrogenenergy system based on methanol electrolyzer
Budak, Yagmur; DEVRİM, YILSER (Wiley, 2020-10-01)
In this study, it is aimed to meet the annual electricity and heating needs of a house without interruption with the photovoltaic panel, wind turbine, methanol electrolyzer, and high temperature proton exchange membrane fuel cell system. The system results show that the use of the 2 WT with 18 PV was enough to provide the need of the methanol electrolyzer, which provides requirements of the high temperature proton exchange membrane fuel cell. The produced heat by the fuel cell was used to meet the heat requ...
