“…These offer the advantage that other effects such as AOI, spectrum and temperature can be controlled and excluded from the investigation. A common approach used is the acquisition of the current-voltage (I-V) curves at the cell or module level using solar flash simulators, which allow the evaluation and comparison of the efficiency at different specified irradiance levels indoors (Bunea et al, 2006;Reich et al, 2009). Similarly, the effects of solar irradiance have been investigated in outdoor evaluations by first acquiring I-V curves at again cell or module level and secondly correcting the acquired data-sets to STC temperature, by using measured or manufacturer temperature coefficients (Merten & Andreu, 1998;Paretta et al, 1998).…”

“…The cells are produced by sawing a square cast block of silicon first into bars and then into wafers. The wafers are square shaped hence less silicon is wasted during manufacturing compared to the production of mono-crystalline cell [41], [46], [47]. The cell consists of small crystals known as crystallites with visible crystal grain.…”

“…Over the years, the CIGS cell has been poised to be the promising cell and thus many companies and research institutes took particular interest in it. The companies and institutes drive research geared towards improving the lifecycle reliability, power output efficiency and cost of modules made using the cells [44], [47], [60], [61]. In recent years, the supply of CIGS cells has dwindled causing major manufacturing companies like Nanosolar and Solyndra to be out of business.…”

“…The thin film PV cells possess lower cost ($/W) than the crystalline silicon PV cells. The cost per wattage of CdTe, CIGS, amorphous silicon, poly-crystalline and mono-crystalline are $0.7/W, $0.75/W, $0.8/W, $1.4/W and $1.6/W, respectively [46], [47], [114], [115]. In the case of limited space applications, the crystalline silicon PV cells are more suitable as they occupy a maximum of 9 m 2 for every 1 kW of power produced while the thin film cells cover a minimum of 9 m 2 per 1 kW power generated [114].…”

The global adoption and use of photovoltaic modules (PVMs) as the main source of energy is the key to realising the UN Millennium Development Goals on Green Energy. The technology -projected to contribute about 20% of world energy supply by 2050, over 60% by 2100 and leading to 50% reduction in global CO 2 emissions -is threatened by its poor performance in tropical climate. Such performance discourages its regional acceptance. The magnitude of crucial module performance influencing factors (cell temperature, wind speed and relative humidity) reach critical values of 90°C, 0.2 m/s and 85%, respectively in tropical climates which negatively impact module performance indices which include power output (PO), power conversion efficiency (PCE) and energy payback time (EPBT). This investigation reviews PVM technologies which include cell, contact and interconnection technologies. It identifies critical technology route(s) with potential to increase operational reliability of PVMs in the tropics when adopted. The cell performance is measured by PO, PCE and EPBT while contacts and interconnections performance is measured by the degree of recombination, shading losses and also the rate of thermo-mechanical degradation. It is found that the mono-crystalline cell has the best PCE of 25% while the Cadmium Telluride (CdTe) cell has the lowest EPBT of 8-months. Results show that the poly-crystalline cell has the largest market share amounting to 54%. The CdTe cell exhibits 0% drop in PCE at high-temperatures and low irradiance operations -demonstrating least affected PO by the conditions. Further results establish that back contacts and back-to-back interconnection technologies produce the least recombination losses and demonstrate absence of shading in addition to possessing longest interconnection fatigue life. Based on these findings, the authors propose a PVM comprising CdTe cell, back contacts and backto-back interconnection technologies as the technology with latent capacity to produce improved performance in tropical climates.

Thus, solar energy is abundant in addition to being clean, sustainable and renewable [2], [3]. Surprisingly, some parts of the world are still struggling to meet their energy needs. It may suffice to say that the regions experiencing energy issues may be having energy conversion problems rather than energy supply problems [2], [4]. It is projected that if 100% exploitation of the energy potentials of the sun ca...
