(author), West, K.J. (author)The new Dutch government (Rutte IV) has agreed in its coalition agreement to reduce greenhouse gas emissions in the Netherlands by at least 55% by 2030 (compared to 1990) and to achieve greenhouse gas emissions neutrality by 2050, implementing the new European objectives. The coalition agreement also proposes a climate target for circular...report 2022

Kazaz, T. (author), Janssen, G.J.M. (author), Romme, J. (author), van der Veen, A. (author)In wireless networks, an essential step for precise range-based localization is the high-resolution estimation of multipath channel delays. The resolution of traditional delay estimation algorithms is inversely proportional to the bandwidth of the training signals used for channel probing. Considering that typical training signals have limited...article 2021

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

(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. Comparison to recent measured data with the BIFOROT set-up at the Zurich University of Applied Sciences showed very good agreement. Our...conference paper 2018

(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. Using carrier-selective contacts based on doped polysilicon layers combined with tunnel oxides,...conference paper 2018

We have found that the inhomogeneity of the rear irradiance depends on orientation, elevation, and tilt angle of the panel and on irradiance conditions. Typically the inhomogeneity of the rear...conference paper 2017

(author)Bifacial photovoltaic (PV) modules make optimal use of diffuse and ground-re?ected light. The gain in energy yield depends on both the local climatic conditions and the PV system layout. These determine the additional irradiance on the rear of the PV panels. The rear response of the (laminated) solar cell(s) determines how much additional energy...article 2017
