\begin{abstract}
This paper proposes an improved single-diode modeling approach for PV modules suitable for a broad range of the PV technologies available today, including modules on tandem cell structures. After establishing the model (which has an overall of seven parameters), the paper devises a methodology to estimate its parameters using Standard Test Conditions (STC) data, Nominal Operating Cell Temperature (NOCT) data, and temperature coefficients values as provided in most manufacturers' datasheets. Simulation results and their comparison with a previous work show a very accurate prediction of critical points in the current-voltage characteristics curve. The precise prediction happens for both STC and NOCT conditions and the error in predicting maximum power point lies within $1\%$ limit, and the error in its corresponding voltage and current is almost always within $2\%$ limit. Further, for both maximum power point and open-circuit voltage, the statistical variance around manufacturer measurements due to temperature changes is demonstrated to be low for five various module technologies.

\label{section:introduction}
\textit{Solar photovoltaics (PV)} is one of the fastest growing power industries in the world thanks to its appealing merits,like the widespread accessibility to natural solar resources, high reliability, easy integration into buildings and structures, fast installation, modularity, and predictable annual output. Between 2000 and 2013, total PV production has been experiencing annual growth rates between $40\%$ and $90\%$ reaching an overall increase of two orders of magnitude. By 2010, thin film PV technologies accounted for around $13\%$ of the PV market share. The values were distributed as follows: $5\%$ for a-Si, for $2\%$ Copper indium di-selenide/Copper indium gallium selenide (CIS/CIGS), and $6\%$ for Cadmium Telluride / Cadmium sulfide (CdTe/CdS). However, most of the efforts in modeling PV modules focus on modules on crystalline silicon (c-Si) cells technology which exhibits characteristics closer to ideal cells. Thus, it is necessary to develop generalized models suitable for different types of technologies \footnote{this is a footnote test}.

% The IEEE uses Times Roman font, so we'll default to Times.
% These three commands make up the entire times.sty package.
\renewcommand{\sfdefault}{phv}
\renewcommand{\rmdefault}{ptm}
\renewcommand{\ttdefault}{pcr}
在 Times 中排版\renewcommand{\rmdefault}{ptm}已经被弃用了大约 20 年，但显然这段时间还不足以实现这一目标。例如，数学公式在 Computer Modern 中排版的最终效果非常糟糕，因为这两种字体在视觉上不兼容。
不过，您可以使用以下方式获取 Times fontspec：添加
\setmainfont{TeX Gyre Termes}
到文档序言。数学仍将属于计算机现代，但显然 IEEE 的人对糟糕的排版感到满意。
如果您想要更好的排版，添加
\usepackage{newtxmath}

for both maximum power point and open-circuit voltage,
the statistical variance around manufacturer measurements

\section{Introduction}
\label{section:introduction}
Some math just to see what happens: $a+2b=3c$.
\textit{Solar photovoltaics (PV)} is one of the fastest
growing power industries in the world thanks to its
appealing merits,like the widespread accessibility
to natural solar resources, high reliability, easy
integration into buildings and structures, fast installation,
modularity, and predictable annual output. Between 2000~and~2013,
total PV production has been experiencing annual growth rates
between $40\%$ and $90\%$ reaching an overall increase of two
orders of magnitude. By 2010, thin film PV technologies accounted
for around $13\%$ of the PV market share. The values were
distributed as follows: $5\%$ for a-Si, for $2\%$ Copper
indium di-selenide/Copper indium gallium selenide (CIS/CIGS),
and $6\%$ for Cadmium Telluride / Cadmium sulfide (CdTe/CdS).
However, most of the efforts in modeling PV modules focus on
modules on crystalline silicon (c-Si) cells technology which
exhibits characteristics closer to ideal cells. Thus, it is
necessary to develop generalized models suitable for different
types of technologies\footnote{this is a footnote test}.
