Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The study of the properties of solar cells is a relevant topic since the development of solar energy corresponds to the global trend and the course of the Government of the Republic of Kazakhstan on the transition to a «green» economy. Various properties of solar cells such as resistivity and surface resistance, carrier lifetime, reflectivity, quantum efficiency, directly affect the efficiency of solar cells. This paper is devoted to obtaining and comprehensive study of solar cells manufactured on the basis of the Kazakhstani silicon of «solar» quality. The study applied: a method of microwave detected photoconductive decay (μ-PCD), four probe methods for measuring resistance, methods for spectrometric analysis of reflection, transmission and photoluminescence coefficients, scanning electron microscopy, and methods for analyzing current-voltage characteristics. The mastered methods of solar cells production are described. A modification of the standard Back Surface Field (BSF) cell line to the Passivated Emitter and Rear Cell (PERC) line has been proposed.
