I know how simple this question is but I just cannot find the solution anywhere on the net or in the help files. I have data in a cell on a sheet in Excel with a border set around the cell. I want to copy the data to another sheet but without the border. The following code works for the data but it also copies the border. Worksheets("Sheet1").Range("B4") py _

1 Introduction. In the early 1970s, Schwartz and Lammert developed the first interdigitated back contact (IBC) solar cells. [] In the nascent stages, IBC cell design was optimized for concentrator application to cope with the high intensities of incoming energy fluxes and the related high current densities. [] Due to its inherent advantages, this cell architecture

Without illumination, the solar cell has the same characteristics as that of a normal p–n junction diode under forward bias condition. This current is known as dark current. However, when sunlight shines on the solar cell, the IV curve starts shifting to fourth quadrant thereby generating power and with increase in the intensity of sunlight, the shift toward fourth

A research team from South Korea’s Ulsan National Institute of Science & Technology (UNIST) has designed a wire-free transparent solar cell and module with all electrical contacts placed on the rear side. A 16 cm² module achieved a power conversion efficiency of 14.7% and successfully charged a smartphone using natural sunlight.
Researcher Jeonghwan Park and Research Assistant Prof. Kangmin Lee said the study “fundamentally solved the aesthetic problem of the existing solar cell modularization method.” They explained that the transparent silicon solar cell could be used in various industries and in small devices, as well as buildings and automobile glass.
Transparent solar cells (TSCs) have attracted considerable attention as they can overcome the limitations of traditional non-transparent solar cells 1, which can convert diverse components, such as architectural windows, agricultural sheds, glass panels of smart devices, and even human skin into energy harvesting devices.
“We plan to continue further research so that transparent solar cells can become a key technology in the eco-friendly future energy industry.” In March, a UNIST research team designed a PV-powered scalable photoelectrochemical system that produces green hydrogen.
A 16 cm² module achieved a power conversion efficiency of 14.7% and successfully charged a smartphone using natural sunlight.
