Cesar, I. (author), van Aken, B.B. (author), Scholten, L. (author), de Goede, R. (author), Schotman, A. (author)De aanleg van zonneparken in het buitengebied is een sterke troef in het versnellen van de energietransitie. De bodemkwaliteit in Nederlandse zonneparken komt echter in toenemende mate onder druk te staan doordat panelen te dicht op elkaar geplaatst worden. De afname in grondbelichting zorgt voor een afname van vegetatie en koolstofgehalte van...article 2022

Yamaguchi, S. (author), van Aken, B.B. (author), Stodolny, M.K. (author), Loffler, J. (author), Masuda, A. (author), Ohdaira, K. (author)System voltages can cause significant degradation in photovoltaic modules. Polarization-type potential-induced degradation (PID) is accompanied by decreases in the short-circuit current density and the open-circuit voltage. The system voltage causes a polarization and surface charge accumulation, increasing the interface recombination. The...article 2021

(author)Solar electricity from solar parks in rural areas are cost effective, can be deployed fast and can therefore play an important role in the energy transition. The optimal design of a solar park is, amongst others, affected by income scheme, electricity transport capacity and land lease costs. Important design parameters for utility-scale solar...conference paper 2021

(author)In this article, we present the results of aging tests of silicon photovoltaic modules with a copper-containing electrode deposited in one-step screen printing method. For front metallization, a mixture of commercial silver paste with copper filler was used, where copper constituted 30% of total paste volume. The filler is based on copper...article 2021

van Aken, B.B. (author), Binani, A. (author), Cesar, I. (author)Solar parks in rural areas are important in the energy transition in the Netherlands as this form of solar energy is very cost effective and can be deployed fast. Potential negative side effects of these solar parks are that they may affect the landscape, the biodiversity and the soil quality underneath the panels. Especially in many east-west...report 2021

Barros, E.G.D. (author), van Aken, B.B. (author), Burgers, A.R. (author), Sloof-Hoek, L.H. (author), Fonseca, R.M. (author)The scarcity of land near energy demand poses the challenge of designing multi-functional solar parks in terms of land use in some countries. This requires solutions accounting for multiple conflicting objectives, e.g., power generation and multi-functional use of the land (agricultural, construction, ecological). Moreover, the performance of...article 2021

(author)The most expensive non-silicon component of solar cells remain silver used for front contact. We propose a single step deposition of Cu/Ni metallization by screen printing method. It was achieved by coating the copper powder with a barrier layer mainly consisting of nickel, in a simple electroless process and then mixing it with a commercial...conference paper 2020

Ramesh, S. (author), Janssen, G.J.M. (author), van Aken, B.B. (author)From energy yield simulations we found that modules with the same nominal efficiency and bifaciality, but with varying combinations of VOC, ISC and FF, have different yields at the same operating conditions. For three climatic zones IV parameters have been identified that will, at the same nominal efficiency, have the largest positive impact on...conference paper 2019

van Aken, B.B. (author), Janssen, G.J.M. (author)Bifacial cells and modules collect light falling not only on the front side of the panels but also on the rear; this additional collection of light increases the total absorbed irradiance, and accordingly the generated current. One of the remaining questions is: what temperature do bifacial solar panels operate at compared with monofacial panels...article 2019

(author)Potential-induced degradation in n-type modules is typically associated with a surface polarization effect. This paper shows that modifications at the cell level can minimize the potential-induced degradation of modules caused by a polarization effect. As is demonstrated on n-PERT cells, the potentialinduced degradation can be reduced...article 2019

Valckenborg, R.M.E. (author), van Aken, B.B. (author)The principle PV module product rating instrument is the DC power at Standard Test Conditions (STC). For a full year energy prediction, additional performance parameters (e.g. NOCT) have been introduced but have left room for improvement. The newly IEC 61853 norm defines a Pmpp-matrix with 7 settings of GPOA and 4 settings of Tmod, which enables...conference paper 2019

(author)The energy yield of PV systems with horizontal single-axis tracking and bifacial panels was calculated using BIGEYE. BIGEYE is a versatile code developed at ECN part of TNO to calculate the yield of bifacial PV.

(author)The performance of current industrial solar cells is for a large part limited by recombination at metallic contacts. A solution to overcome this is to screen minority carriers from the metal by using so-called passivating carrier-selective contacts.

(author)We characterize four types of bifacial modules with three different methods that have been proposed by the community. One method approximates rear irradiance with increased front side irradiance. The other two utilize light directly radiating on the rear side of the module.

Slamberger, J. (author), Schwark, M. (author), van Aken, B.B. (author), Virtic, P. (author)Potential-induced degradation (PID) of photovoltaic (PV) modules is one of the most severe types of degradation, where power losses on system level may even exceed 30%. The PID process depends on the strength of the electric field, the temperature, the relative humidity, conductive soiling, time and the PV module materials. For p-type cells, it...article 2018
