Analytical Modeling of the Maximum Power Point with Series Resistance
Garcia, Alfredo Sanchez; Strandberg, Rune (Peer reviewed; Journal article, 2021)This paper presents new analytical expressions for the maximum power point voltage, current, and power that have an explicit dependence on the series resistance. An explicit expression that relates the series resistance ... -
Analytical Modeling of the Temperature Sensitivity of the Maximum Power Point of Solar Cells
Garcia, Alfredo Sanchez; Kristensen, Sissel Tind; Strandberg, Rune (Peer reviewed; Journal article, 2022)Abstract—This article presents new analytical expressions for the temperature coefficients of the voltage, current, and power of a solar cell at its maximum power point MPP). A new analytical expression of the temperature ... -
Detailed balance analysis of area de-coupled double tandem photovoltaic modules
Strandberg, Rune (Journal article; Peer reviewed, 2015)This paper describes how layers of area de-coupled top and bottom cells in photovoltaic tandem modules can increase the efficiency of two-terminal tandem devices. The point of the area de-coupling is to allow the number ... -
Heat to electricity conversion by cold carrier emissive energy harvesters
Strandberg, Rune (Journal article; Peer reviewed, 2015) -
A high-accuracy calibration method for temperature dependent photoluminescence imaging
Kristensen, Sissel Tind; Nie, Shuai; Wiig, Marie Syre; Haug, Halvard; Berthod, Charly; Strandberg, Rune; Hameiri, Ziv (Journal article; Peer reviewed, 2019) -
On the Variability of the Temperature Coefficients of mc-Si Solar Cells with Irradiance
Berthod, Charly; Strandberg, Rune; Yordanov, Georgi Hristof; Beyer, Hans-Georg; Odden, Jan Ove (Journal article; Peer reviewed, 2016) -
Optimal samleskinnekonfigurasjon for 66-420 kV-anlegg
Svarverud, Ingvild Solheim (Master thesis, 2023)Blant viktige byggestener i kraftnettet er transformatorstasjonene. Disse består av samleskinner, transformatorer, effektbrytere samt andre komponenter. Samleskinnene og de tilkoblede komponentene utgjør samleskinnekonfi ... -
Reduced temperature sensitivity of multicrystalline silicon solar cells with low ingot resistivity
Berthod, Charly; Strandberg, Rune; Odden, Jan Ove; Sætre, Tor Oskar (Chapter, 2016) -
Reduction of temperature coefficients in multicrystalline silicon solar cells after light-induced degradation
Berthod, Charly; Strandberg, Rune; Odden, Jan Ove; Sætre, Tor Oskar (Chapter; Peer reviewed, 2015) -
Spectral and temperature sensitivity of area de-coupled tandem modules
Strandberg, Rune (Chapter; Peer reviewed, 2015)Area de-coupling is a recently suggested method for current- or voltage-matching two-terminal tandem modules. It has previously been shown that under standard conditions, area de-coupled modules have the same theoretical ... -
Temperature coefficients of compensated silicon solar cells - influence of ingot position and blend-in-ratio
Berthod, Charly; Strandberg, Rune; Odden, Jan Ove (Journal article; Peer reviewed, 2015)Solar-grade silicon made from a metallurgical route presents boron and phosphorus compensation. Earlier work has shown that cells made from such material produce more energy than reference polysilicon modules when the ... -
THE LIMITING EFFICIENCY OF FOUR-BAND CELLS REVISITED
Strandberg, Rune (Journal article; Peer reviewed, 2014)The limiting theoretical efficiency of four-band solar cells is revisited. In previous work, researchers have looked at the theoretical efficiency of four band cells where the smallest of the three sub-band gaps is closest ... -
Theoretical efficiency limits for thermoradiative energy conversion
Strandberg, Rune (Journal article; Peer reviewed, 2015)A new method to produce electricity from heat called thermoradiative energy conversion is analyzed. The method is based on sustaining a difference in the chemical potential for electron populations above and below an ... -
Using transfer coefficients to model series-connected multi-junction solarcells with radiative coupling
Strandberg, Rune (Peer reviewed; Journal article, 2023)When the quality of multi-junction solar cells becomes sufficiently high, radiative exchange of photons between cells must be included to properly model such devices. In this work, it is shown how constants called transfer ... -
Vedlikehold av stolpene i distribusjonsnettet i Agder - Levetidsstudie
Homme, Liv Hege Ketilsdotter (Master thesis, 2023)This thesis was written in collaboration with Glitre Nett, where the purpose is to analyse the lifespan of power masts in the high voltage distribution grid in Agder. This is done by studying several factors that can impact ...
