As photovoltaic penetration of the power grid increases, accurate predictions of return on investment require accurate prediction of decreased power output over time. Degradation rates must be known in order to predict power delivery. This article reviews degradation rates of flatplate terrestrial modules and systems reported in published literature from field testing throughout the last 40 years. Nearly 2000 degradation rates, measured on individual modules or entire systems, have been assembled from the literature, showing a median value of 0.5%/year. The review consists of three parts: a brief historical outline, an analytical summary of degradation rates, and a detailed bibliography partitioned by technology.

The temperature dependence of silicon (Si)-based thin-film single-junction solar cells, whose intrinsic absorbers were fabricated on the transition phase between hydrogenated amorphous silicon (a-Si:H) to hydrogenated microcrystalline silicon (mc-Si:H), was investigated. By varying the hydrogen dilution ratio, wide-band-gap protocrystalline silicon (pc-Si:H) and mc-Si:H absorber layers were obtained. Photo-current density-voltage (Photo-J-V) characteristics were measured under AM1.5 illumination at ambient temperatures in the range of 25 -75 C. We found that the solar cells with pc-Si:H, which exists just below the a-Si:H to mc-Si:H transition boundary, showed the lowest temperature coefficient (TC) for conversion efficiency () and open-circuit voltage (V oc ), while the solar cells fabricated at the onset of the a-Si:H to mc-Si:H phase transition exhibited a relatively high TC for and V oc . Experimental results indicated that pc-Si:H is a promising material for the absorber layer of the single junction or the top cell of tandem solar cells that operate in high temperature regions.

“…Among Si-based solar cells, bulk crystalline Si solar cells including single crystalline-Si (c-Si) and polycrystalline-Si (poly-Si) solar cells show higher η than thin film solar cells at STC. However, η of c-Si and poly-Si solar cells seriously decreases with an increase in the operating temperature, while hydrogenated amorphous Si (a-Si:H)-based thin film solar cells reveal relatively small variation in η [4][5][6][7]. The main reason for the lower TC for a-Si:H-based solar cells is due to their wide band gap intrinsic absorber or high V oc compared with bulk crystalline Si-solar cells.…”

The temperature dependence of silicon (Si)-based thin film single junction solar cells whose intrinsic absorbers were fabricated near the phase boundary of hydrogenated amorphous silicon (a-Si:H) to hydrogenated microcrystalline silicon (µc-Si:H) was investigated. By varying the hydrogen dilution ratio, wide bandgap protocrytalline silicon (pc-Si:H) and the mixed-phase of a-Si:H and µc-Si:H absorber layers were obtained. Photo J-V characteristics were measured under AM1.5 illumination at ambient temperature in the range of 25-75 o C. We found that the pc-Si:H solar cells which exist below the a-Si:H and µc-Si:H transition boundary exhibited the lowest temperature coefficient (TC) for conversion efficiency (η) and open-circuit voltage (V oc ), while the solar cells fabricated at the mixed-phase of a-Si:H and µc-Si:H revealed a relatively high TC for η and V oc . Experimental results indicated that pc-Si:H which fabricated at the silane concentration (SC), SC = [SiH 4 ]/([SiH 4 ]+[H 2 ]), of 5.75% showed the highest initial η, low TC for η and degradation ratio. This material at this condition is a promising for using as an absorber layer of single junction or top cell for tandem solar cells which operating in high temperature regions.
