[PDF Version]Concerning the global photovoltaic solar industry, the upstream sector gets the highest profits, as competition is relatively small, and the market tends to be oligopolistic (Liu and Lin, 2019). Upstream groups involve companies that have a high and specific technological level, with a high investment cost in the facilities.
Broadly speaking, the PV manufacturing environment has been challenging in terms of overall profitability. Since 2010, gross margins have varied between 5% and 25%, while operating margins have varied between 15% and -15% (Feldman, O'Shaughnessy et al. 2020).
The operating margin, R&D expenses, and SG&A expenses together constitute the gross margin. Broadly speaking, the PV manufacturing environment has been challenging in terms of overall profitability.
In addition, variation in the cost and availability of labour, premises and services are also influential to the profit a solar panel business can make. The economics of solar panel installation are also dependent on the resource potential available for energy production.
The profit margin of the photovoltaic supply chain, resulting from the reduced costs of operation, design, and maintenance of the system, represents another determining factor for the competitiveness of the sector (He et al., 2017, Lee et al., 2012, Liu et al., 2017, Liu and Lin, 2019, Wijeratne et al., 2019, H.J.J. Yu, 2018).
One of the major factors that can effectively influence the level of profitability of a solar panel business is the degree of competition in the market. If there is a lot of competition in the market, then the profit of these installation companies will naturally be lower.

If future missions designed to probe environments close to the Sun will be able to use photovoltaic power generation, solar cells that can function at high temperatures under high light intensity and high radiation conditions must be developed. The sig-nificant problem is that solar cells lose performance at high temperatures.
For silicon PV cells, the average temperature coefficient for power output is around -0.4%/°C. This means for each degree above 25°C, the efficiency of the panel may decrease by 0.4%. Continuously operating at high temperatures can also lead to accelerated aging of photovoltaic modules. This can manifest in several ways:
For example, thin-film solar cells, although less efficient at room temperature, often perform better at higher temperatures relative to silicon PV cells. Thermal Buffering Materials: Using materials that can absorb and reradiate heat can help manage the temperature of the solar cells throughout the day.
Choosing the Right Materials: Some newer photovoltaic materials and technologies have lower temperature coefficients than standard silicon cells. For example, thin-film solar cells, although less efficient at room temperature, often perform better at higher temperatures relative to silicon PV cells.
Semiconductor Properties: Most photovoltaic cells are made from silicon, a semiconductor whose electrical properties change with temperature. As temperature increases, the band gap of silicon decreases, leading to fewer electrons being able to jump the energy gap to produce electricity.
Since the fractional loss of Voc with temperature de-creases in magnitude as bandgap increases , photovoltaic cells from wide-bandgap materials can operate at higher intensity (so higher temperatures) than cells from narrow-bandgap materials .
