After 30 years of development, photovoltaic (PV) technology has been recognised to be capable of contributing significantly to future energy supply. The global cumulative installed PV power now exceeds 180 GW p , and the annually installed power exceeds 40 GW p. The cost of electrical energy produced by PV systems is now close to that from conventional sources. This study discusses the physics, construction and manufacture of PV cells and modules, taking into account current trends in technology. All parts of PV systems that influence the cost of the electrical energy produced are considered. Three generations of PV module are described. Crystalline silicon (c-Si) is and will remain the dominant PV material at least until 2020 because of its high efficiency, long service time and relatively low cost. It represents nearly 90% of total module production. There are no material supply constraints to limit production and a decrease in c-Si PV module cost to below 0.4 €/W p before 2017 can be expected. PV power generation will reach industrial grid parity before 2020 and a cumulative installed power of 1 TW p is expected before 2025.

Impressive progress in PV technology over the past thirty years is evident from the lowering costs, the rising efficiency and the great improvements in system reliability and yield. Yearly growth rates in the last decade (2003-2013) were on an average higher than 40%, and the global cumulative PV power installed reached 140 GWp in 2013 and photovoltaic power installed in 2013 overcome 30 GWp. The workhorse of present photovoltaics is crystalline silicon technology. Basic principles of photovoltaic cell physics and technology have been demonstrated on fabrication of crystalline silicon cells and modules, also new prospective technologies. Differences between technologies are discussed and present domination of crystalline silicon technology is explained. The aim is to give information important for understanding basic problems of physics, construction and manufacturing photovoltaic cells and modules.

“…Summarizing the results of performed experiments, the authors emphasized signicant inuence of temperature on the crucial operating parameters of solar cells. In addition, the research described in [7] showed that the eciency of PV cells substantially depends on the level of solar radiation and resistance of the substrate material of which the cell is constructed. Simultaneously, in [7,8], it was conrmed that along with the increase of the operating temperature of a PV cell, it is possible to observe a signicant decrease in the values of indicators determining the quality of the considered PV cell such as open-circuit voltage, maximum power, ll factor and eciency.…”

Considering the results of recent research, it is possible to state that the problem of thermal stability of electrical parameters of silicon is very important in the context of eciency of commonly used photovoltaic cells. Subsequent investigations conrmed that the eciency of photovoltaic cells is strongly inuenced by active defects of silicon crystal lattice. Those defects, arising in the process of photovoltaic cells base material preparation, are responsible for changes in the values of conductivity and activation energy of the tested material. Taking this into consideration, it is reasonable to carry out research oriented at experimental verication of the inuence of both operating temperature on the electrical parameters of silicon and annealing temperature on the distribution of radiation defects in the silicon substrate used in the production of photovoltaic cells. The main purpose of this work is a comparative analysis of dependences of electrical parameters of silicon on temperature. The article presents the results of the research on resistivity and capacity of silicon samples (doped with boron and phosphorus) whose structure was modied by the ion implantation process.
