Collection asymmetry in a drift-driven p-i-n solar cell Asensi López, José Miguel Soler Vilamitjana, David Fonrodona Turon, Marta Bertomeu i Balagueró, Joan Andreu i Batallé, Jordi Cèl·lules solars Silici Substàncies amorfes Solar cells Silicon Amorphous substances An analytical expression for the voltage dependence of the internal collection efficiency of amorphous silicon p-i-n solar cells is presented. The influence of arbitrary drift lengths (asymmetrical case) is taken into account and it is shown how this asymmetry affects the spectral dependence of the collection. A new experimental technique is proposed to determine the so-called collection voltage. Comparison between preliminary experimental data and theoretical results reveals the limitations of the analytical description. 2016-05-05T16:55:59Z 2016-05-05T16:55:59Z 2002 2016-05-05T16:56:05Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 0022-3093 https://hdl.handle.net/2445/98360 188306 eng Versió postprint del document publicat a: http://dx.doi.org/10.1016/S0022-3093(01)01082-1 Journal of non-Crystalline Solids, 2002, vol. 299-302, p. 1142-1146 http://dx.doi.org/10.1016/S0022-3093(01)01082-1 (c) Elsevier B.V., 2002 info:eu-repo/semantics/openAccess 5 p. application/pdf Elsevier B.V.
