WebOver the past decade, the power conversion efficiency (PCE) of single-junction PSCs has surpassed 25%, for devices fabricated in both n-i-p (regular) and p-i-n (inverted) structures, on par with state-of-the-art crystalline silicon solar cells. Further improvements to the efficiency of single-junction devices will become increasingly difficult as the field … WebMar 18, 2024 · 1 Introduction. Cu(In,Ga)Se 2 (CIGS) is a promising photovoltaic absorber because of the thin film processibility, high power conversion efficiency (PCE ≈23.35%), [] long-term stability, [] and bandgap tunability. [] While Na has been the key dopant for advancing the CIGS solar cell, the recent efficiency boosting is, with no doubt, driven by …

http://www.envirobiotechjournals.com/EEC/vol28decsuppl22/EEC-6.pdf WebMar 19, 2024 · Organic solar cells, for example, are between 50 and 300 nm thick and comprise p-i-n structure (A bulk-heterojunction solar cell can be considered as p-i-n type as the bulk is usually undoped). ... The shunt resistance is extracted from the reverse current of the dark JV-curve or OCVD. taillepied mathilde
Anisotropic Charge Transport in Cu(In,Ga)Se2 by Heavy Alkali ...
WebOrganic solar cells (OSCs) based on polymer donor and non-fullerene acceptor achieve power conversion efficiency (PCE) more than 19% but their poor absorption below 550 nm restricts the harvesting of high-energy photons. ... Shunt resistance (R SH) and series resistance (R S) ... WebEspecially in organic solar cells, the shunt und series resistance is strongly affected by the thickness of the active layer. Typically, small active-layer thicknesses result in lower series and parallel resistances, although the parallel resistance underlies a certain random distribution due to possible defects in the active layer.
