“…It is confirmed by the available literature studies [11][12][13][14], and author's experience [7,8], The analysed literature data and own research carried out on front electrodes indicate that the best properties (electrical and structural) are demonstrated by the test system burnt out in the furnace and obtained from the commercial paste. The coating process of silicon layer using the silk-screen printing is time-consuming and difficult to automate.…”

Photovoltaic cells are one way of achieving solar energy. One of the stages of their fabrication is the production of front electrode. The application of an unconventional method of selective laser sintering using the CO 2 laser for the fabrication of front electrode of silicon photovoltaic cell was a real challenge. The most notable research results yielded by the research indicate what should be the focus of further investigation. The main objective of the paper is to work out the guidelines to be applied to laser micromachining of the front electrode of the photovoltaic cell concerning the selection of parameters such as the laser beam and laser beam feed rate, which give the possibility to assure its proper quality and suitable operating properties (including also its electrical properties). The investigation results obtained should yield the precise assessment of the laser micromachining conditions for the fabrication of front electrode of photovoltaic cells to improve their quality by the minimization of the Ag-Si interface resistance.

“…Figure 3 illustrates a high efficiency silicon cell showing some of the measures necessary to reduce surface recombination, optimise absorption and reduce reflection. These issues are discussed in detail elsewhere 8 . The silicon used to achieve these efficiencies was single crystal magnetically-confined Czochralski or float zone.…”

Solar power is seen by many as a solution to the world’s energy problems. The earth receives 1.7x1017W from the sun compared to a total electricity generation capacity of 4.6x1012W (OECD prediction for 2010). However the average power density is low with a daytime average over the earth of 680Wm-2. This makes centralised generation problematic but distributed photoelectric generation by domestic and commercial users is a rapidly developing market. However typical commercially available modules have an energy conversion efficiency of less than 12%. Silicon cells with 24% efficiency have been produced in the lab while multi-junction tandem cells using different semiconductor materials (GaInAs, GaInP and Ge) to absorb different parts of the sun’s spectrum have reached 40%. This chapter describes some of the materials and device achievements so far and looks at possible ways in which higher efficiencies might be achieved with particular emphasis on nano-materials to use more of the solar spectrum efficiently. The possibility of using quantum slicing and multiple exciton generation to make more efficient use of high energy photons is considered and impurity band generation as a possible route to use low energy photons. One of the greatest challenges is to do this cheaply using semiconductors made from non-toxic abundant elements.

“…The interest to photovoltaic (PV) solar cells as a source of energy for a variety of applications has been rapidly increasing in recent years [1][2][3][4][5][6][7][8][9][10]. Improving solar cell performance is an important issue, and the efforts have been mostly aimed at increasing power conversion efficiency and reducing manufacturing costs.…”

Abstract:We report results of experimental investigation of temperature rise in concentrated multi-junction photovoltaic solar cells with graphene-enhanced thermal interface materials. Graphene and few-layer graphene fillers, produced by a scalable environmentally-friendly liquid-phase exfoliation technique, were incorporated into conventional thermal interface materials. Graphene-enhanced thermal interface materials have been applied between a solar cell and heat sink to improve heat dissipation. The performance of the multi-junction solar cells has been tested using an industry-standard solar simulator under a light concentration of up to 2000 suns. It was found that the application of graphene-enhanced thermal interface materials allows one to reduce the solar cell temperature and increase the open-circuit voltage. We demonstrated that the use of graphene helps in recovering a significant amount of the power loss due to solar cell overheating. The obtained results are important for the development of new technologies for thermal management of concentrated photovoltaic solar cells.
