The manufacturing process of choice would depend in large part on the production demand of the entity and how much capital is available for investment in manufacturing equipment. Recent technological advances have warranted continued research to improve performances of polymer solar panels. The attributes that are key to improving overall performance include higher power conversion efficiencies and increased lifetime of the polymer solar cells. For instance, CiBER Labs (Simon Fraser University) is conducting research on integrating nanoscale structures into PSCs to potentially enhance their performances. Higher power conversion efficiencies will increase energy production capacity of a manufacturing process, thereby reducing the unit manufacturing cost of power produced.
On solving interrelated technological and transport problems for deep open pit mining

Improvement to transfer points can increase the production efficiency by significant amounts. Screen analysis of the mined rock shows that 80 to 97 % of the rock can be transported without prior crushing. This means that crusher production is plugged with undersized material, and can lead to a bottleneck at the crusher. It also results in the need for: higher power consumption, higher wear of equipment, and increased downtime for repairs.

In this section, the results obtained from the considered system are presented and discussed. The system is investigated in terms of power density, energy efficiency, exergy destruction density, ecological function. Variations of these parameters are shown in Figures 2–8 and p–η–e charts are drawn in Figures 9 and 10. The parameters used in calculations can be seen in Table 1. The current density is the main parameter affecting the performance of the hybrid system, PEMFC, CHP and AR. To assess the performance of the hybrid system PEMFC, CHP and AR, a parametric analysis should be conducted and the effects of the current density should be described. The maximum points of power output, the energy efficiency and ecological function, which are called optimum points, were found. As it is known, power output is desired to be maximum for any energy system. The higher power output means the higher energy efficiency (if the energy source is constant), and this causes to prevent the waste of energy resources. The maximum ecological function provides anyone to detect the point where the difference in the power output and exergy destruction is the greatest. In the analysis, the current density is changed, while the others are kept constant. Mathematica software is used for calculations.
