In this paper, the impact of the back contact barrier on the performance of Cu (In, Ga) Se2 solar cells is addressed. This effect is clearly visible at lower temperatures, but it also influences the fundamental parameters of a solar cell, such as ope

In this contribution, the application possibilities of Kelvin probe mapping on Cu(In,Ga)(Se,S)2 thin-film modules was explored and compared with dark lock-in thermography and electroluminescence imaging techniques. It has been shown that unlike any i

This paper deals with the determination of the height of the back contact diode in CIGS thin film solar cells. Two different methods are explained, namely admittance spectroscopy andV OC (T). Based on the comparison of simulations and experimental da

A graded bandgap structure proved to be an important factor for increasing an overall efficiency of the chalcopyrite-based thin film solar cells. This contribution is focused on the effects of sulfur incorporation into the surface region of industria

We report the development of Cd-free buffers by atomic layer deposition for chalcopyrite-based solar cells. Zn(O,S) buffer layers were prepared by atomic layer deposition on sequentially grown Cu(In,Ga)(Se,S)2 absorbers from Bosch Solar CISTech GmbH.

In this contribution, metastabilities of Cu(In,Ga)Se2 (CIGS)/CdS thin films are discussed based on photoluminescence (PL) imaging and complementary vibrating Kelvin probe (VKP) measurements. It has been shown that thermal treatment of CIGS/CdS thin f
